Ive been getting these strange type errors on my typescript project for certain packages.
Ex:
'TimeAgo' cannot be used as a JSX component.
Its instance type 'ReactTimeago<keyof IntrinsicElements | ComponentType<{}>>' is not a valid JSX element.
The types returned by 'render()' are incompatible between these types.
Type 'React.ReactNode' is not assignable to type 'import("/home/user/app/node_modules/#types/react-bootstrap-table-next/node_modules/#types/react/index").ReactNode'.
Type '{}' is not assignable to type 'ReactNode'.
I don't get these type errors on my local windows machine but they keep occurring in my linux virtual machine. I've deleted the project many times, cloned my repo and installed packages again in different versions of node and I still get the same type errors.
Checked node 12.18.3, 16.13.1
Here is some quick package json info:
"react-timeago": "^6.2.1",
"react-custom-scrollbars": "^4.2.1",
"react-custom-scrollbars-2": "^4.4.0",
"react": "^17.0.2",
"next": "^12.1.1",
"#types/react-custom-scrollbars": "^4.0.10",
"#types/react-timeago": "^4.1.3",
"#types/react": "^17.0.44",
"typescript": "^4.3.5"
"#types/node": "^14.18.12",
This happens on basic custom components:
MyTst.tsx
import TimeAgo from "react-timeago";
const Mytst = () => {
return (
<div>
<TimeAgo date={"02/02/2022"} />
</div>
);
};
export default Mytst;
I get this error for react-custom-scrollbars-2 as well. There seems to be an issue with matching the types correctly between the library which contains the component and the #types files associated with them. Anyone have any ideas on how to resolve these type errors?
Had the same issue.
Just add this
"resolutions": {
"#types/react": "17.0.2",
"#types/react-dom": "17.0.2"
},
to package.json file and run yarn command.
UPD: Just a bit detailed answer:
#types/react-dom has its own dependencies and one of them is #types/react with a version set to '*' - a major release, that now, probably, refers to 18.
Even if you specify some strict versions in your package.json (without ^) parent package might install its own duplicates of packages that you are already using for its own purposes.
By using resolutions we are specifying strict restrictions for dependencies of dependencies.
You will need to fix the version for #types/react package because many react libraries have dependency set as #types/react : "*", which will take the latest version of the package. (I suppose they just released version 18)
To do that you can add this in your package.json
"resolutions": {
"#types/react": "^17.0.38"
}
It will just work fine with yarn, but if you are using npm, then you will also need to add this in "scripts" section of your package.json
"preinstall": "npm install --package-lock-only --ignore-scripts && npx npm-force-resolutions"
This will simply use npm-force-resolutions package to fix versions from resolutions.
And then after doing npm install, your app should work just fine.
I known issued today
rm -rf node_modules
rm -rf yarn.lock
npm install
just used npm install sovled problem
but I don't know what happend
Had this with Styled Components. Resolutions didn't work for me so here's another
solution:
Brute force type casting:
const ThemeProviderFixed = ThemeProvider as unknown as React.FC<PropsWithChildren<{ theme: string }>>;
Sahil's answer is correct for npm and yarn, but if you are using pnpm, you need a slightly different setup in your package.json file:
"pnpm": {
"overrides": {
"#types/react": "^17.0.38"
}
}
If you are using a monorepo with several packages, this only works at the root package.json file of your repo. You can read more about it here in the pnpm docs.
I also had the same issue, so I updated npm version ^6.0.0 -> 8.0.0 and it was resolved.
Check npm version.
I came across this issue recently when upgrading to React 18 and forgetting to upgrade my corresponding types in devDependencies.
What worked for me was upgrading React types to match in the package.json file as shown
{
...
"dependencies": {
...
"react": "^18.1.0",
},
"devDependencies": {
...
"#types/react": "^18.0.8",
}
}
I recently ran into this with a Yarn monorepo where a Typescript create-react-app subproject had installConfig.hoistingLimits=workspace. This configuration prevents hoisting of dependencies to the top-level of the monorepo.
When running react-scripts start, the type checker was still looking at the top-level #types and not finding the matching #types/react for the version of React configured on the project. The fix that resolved it was to add the following to the tsconfig.json in the subproject:
"compilerOptions": {
...
"typeRoots": ["./node_modules/#types"]
},
...
This points Typescript at the type definitions that are installed for the specific sub-project.
Ok. I ended up fixing this problem but to warn you in advance, there wasn't a magical way to do this.
I basically uninstalled all the #types I think were the offenders. You can find this out by reading your error window. The key was this message in my original error above.
Type 'React.ReactNode' is not assignable to type 'import("/home/user/app/node_modules/#types/react-bootstrap-table-next/node_modules/#types/react/index").ReactNode'.
If you see where the node module types are pointing to and its not associated with your library, then remove it. In my case, my issue was the package TimeAgo and the type error was showing that types were assigned to a different package. So I uninstalled it and kept cycling through the errors until it went away.
Then I use npm run build to do type checks and instruct me which types I had to reinstall. (There is probably a better way to do this part but it worked for me even though it was tedious.)
This issue seems to happen when you have a ton of different libraries and their types that have similar dependencies and overtime if they aren't needed, don't do what I do and just keep them piled up in your package.json.
So if you think any type can have conflicts with your library, uninstall and see if the error goes away, and then reinstall if other type errors appear that say the dev type package is missing. I also had some #type packages as dependencies instead of devDependencies which I removed and moved back into dev. Don't know if that played a part.
When in doubt, remove all applicable types and see if the issue is resolved.
If you have older version of npm, just update npm to version > 8.0.0.
It worked for me.
I had npm version 6.x.x. I tried many solutions, but update npm to new version fix this problem easy.
for npm!
check which version of node and npm you have installed.
if you update to 8.x, npm provides you the same thing as resolution does for yarn but its"overrides".
update your package like this:
"overrides": {
"#types/react": "17.x.x",
"#types/react-dom": "17.x.x"
}
my npm and node versions were up to date on local instance, but not on git ci. After the update, it was working without to override the versions for react and react-dom.
Unfortunately in my case I can't use the most voted answer since I need #types18 since I need to use the latest hooks from react#18 like useId and I can't import them using #types/react#17 since they have no exported members for those hooks.
I was able to use latest types fixing the broken typed deps, thanks to #Chris Web' s answer. For example for the Redux Provider:
// temp fix due to #types/react#18
const Provider = _Provider as unknown as React.FC<{
children?: JSX.Element | string;
store: any;
}>;
The store: any is not ideal, but it's just a temp fix.
You can solve this issue by following the above solution for react
"resolutions": {
"#types/react": "17.0.2",
"#types/react-dom": "17.0.2"
},
and for react-native you don't need to add type for react-dom
"resolutions": {
"#types/react": "17.0.2",
},
After this if you still getting error for react types,
add the type package separetly for react
npm install -D #types/react#17.0.2
Note - don't add "^" in resolution as it will try to install the latest version of packages which may cause the same problem.
Problem
For those who have this type of error in the APP and are using yarn instead of npm.
Solution
Just add the to resolutions and preinstall script inside the package.json file and them execute yarn preinstall and yarn.
package.json
"resolutions": {
.....
"#types/react": "^17.0.38"
....
},
"scripts": {
......
"preinstall": "yarn --package-lock-only --ignore-scripts"
......
},

Slightly different answer that worked for me (in case the above doesn't work for you). I had a node_modules folder in my user root. So my project folder looked like this:
~/checkouts/project/node_modules
but I also had a node_modules folder installed at the user root (probably an accident at some point):
~/node_modules
The way npm packages work is it crawls up the directory structure grabbing npm packages along the way. After removing this directory the problem went away.
Tested this on two windows machines one mac and one ubuntu. One win machines was fine (no error on build), the other wind machine gave this error on build. Mac was also fine but ubuntu was also giving this error on build. I was frustrated. Tested with different node versions but that did not help.
In the end had to update some types versions (not sure though if all four needed to be updated but after the update error disappeared):
"#types/react": "^16.14.3",
"#types/react-dom": "^16.9.10",
"#types/react-router": "^5.1.11",
"#types/react-router-dom": "^5.1.7",
to:
"#types/react": "^18.0.15",
"#types/react-dom": "^18.0.6",
"#types/react-router": "^5.1.18",
"#types/react-router-dom": "^5.3.3",
i tried it in two ways, with yarn's resolution it solved it, but then i deleted my yarn.lock and updated the react's type and it worked for me too without using yarn's resolution
yarn upgrade #types/react#^18.0.21
I posted a different answer but it was basically a duplicate answer so I'll provide another approach.
If you're using yarn, you can run yarn dedupe and it will make the necessary changes to your yarn.lock file. It will consolidate any references to the same package to resolve to the correct version. As you can see from here, the - lines are what were removed and the + line is modified and saved:
-"#types/react#npm:*, #types/react#npm:>=15, #types/react#npm:>=16.9.0":
- version: 17.0.43
- resolution: "#types/react#npm:17.0.43"
- dependencies:
- "#types/prop-types": "*"
- "#types/scheduler": "*"
- csstype: ^3.0.2
- checksum: 981b0993f5b3ea9d3488b8cc883201e8ae47ba7732929f788f450a79fd72829e658080d5084e67caa008e58d989b0abc1d5f36ff0a1cda09315ea3a3c0c9dc11
- languageName: node

-"#types/react#npm:^18.0.0":
+"#types/react#npm:*, #types/react#npm:>=15, #types/react#npm:>=16.9.0, #types/react#npm:^18.0.0":
"#types/react#npm:*, #types/react#npm:>=15, #types/react#npm:>=16.9.0"
was consolidated into
"#types/react#npm:*, #types/react#npm:>=15, #types/react#npm:>=16.9.0, #types/react#npm:^18.0.0"
In my case, I put the wrong type of value inside a div.

I am new to SvelteKit and have built an initial project from the SvelteKit docs. When the project opens I receive the following error when looking at index.svelte.
Error in svelte.config.js
Error [ERR_MODULE_NOT_FOUND]: Cannot find package

While the project builds it's throwing errors everywhere. Any help would be appreciated.
I am using VS Code for the project. The issue is related to opening the project in VS Code, opening a terminal, and running the npm install command.
It appears that npm install must be run in an application like Terminal on a Mac prior to opening the app in VS Code.
Had the same issue, edit package.json:
remove line:
"#svelte:qjs/adapter-auto": "next",
then run:
pnpm i #sveltejs/adapter-auto
You may replace pnpm with npm or yarn.
then in package.json, will get something like:
"#sveltejs/adapter-auto": "1.0.0-next.55"
That solved the issue.
My node+npm version was outdated. Make sure you have the latest node version installed.
I've created a repository which contains a React app (created with create-react-app) and a components directory which contains a simple Material UI button. The folder structure is:
/components
/react-app
Both directories are set up to use Yarn 2, and are not in a workspace (as I'm trying to simulate projects in separate directories and simplify my real world scenario).
I build the components:
$ cd ~/components && yarn build
I then Yarn link the components to the React app:
$ cd ~/react-app & yarn link ../components -r -p
This results in a modification to package.json file in the react-app directory:
{
"name": "react-app",
...
"resolutions": {
"components": "portal:../components"
}
}
My App.tsx file looks like this:
import './App.css';
import { Button } from 'components';
import React from 'react';
function App() {
return (
<Button>Test</Button>
);
}
export default App;
However, when I run the React app using yarn start I get the following error:
./src/App.tsx
Module not found: Your application tried to access components, but it isn't declared in your dependencies; this makes the require call ambiguous and unsound.
I'm not sure what I'm doing wrong. If I add an explicit reference to the components directory within dependencies (which I don't believe I should have to do because I've already linked it) such as:
"dependencies": {
"components": "portal:../components"
}
Then I get the error:
./src/App.tsx
Module not found: You attempted to import ~/react-app/.yarn/$$virtual/components-virtual-de9a8055ab/2/components which falls outside of the project src/ directory. Relative imports outside of src/ are not supported.
Surely, I don't have to eject the app and find a way to bypass this error?
EDIT: According to the Yarn documentation "Webpack 5 will support PnP natively, but if you use Webpack 4 you'll need to add the pnp-webpack-plugin plugin yourself". At the time of writing, the latest version of create-react-app relies on v3.4.1 of react-scripts which in turn relies on Webpack 4. I therefore ejected my app to inspect the Webpack configuration, and it appears that this plugin is already installed. It's therefore not a CRA/Webpack issue. I also upgraded my version of Node from v10.16.0 to v12.16.3 to no avail.
TLDR; Add the package as a dependency then modify your React setup to import files outside of the /src directory.
In my case, it doesn't look like yarn link is doing anything other than adding a resolutions entry in package.json, which according to the documentation is only used to specify the version to resolve. Perhaps my understanding of Yarn link is wrong (even though it held up in v1).
To fix the issue I had to add the reference to dependencies in package.json (even though I'd already run yarn link):
"dependencies": {
"components": "portal:../components"
}
This caused the aforementioned You attempted to import components which falls outside of the project src/ directory error. To resolve this we either need to eject the React app and disable the ModuleScopePlugin in Webpack (therefore allowing the import of files outside the /src folder), or use craco with custom configuration. I've created yarn-eject and craco branches to demonstrate both.
It's not a particularly elegant solution, and I'm hoping someone can post a better alternative. I switched to Yarn 2 so that I could utilise the "Improved Peer Dependency Links" feature (so that I'm only relying on one version of react across my applications and shared components packages). I'd rather not have to eject my React app or use custom configuration if possible.
I did "npm install --save -g pondjs" but when I ran my code, I got this error message:
./src/Components/Tseries.js
Module not found: Can't resolve 'pondjs' in '/Users/<ME>/Google Drive/code/React/projectmanager/src/Components'
Here is the header in my js file:
import React, { Component } from 'react';
import { TimeSeries, TimeRange, TimeRangeEvent } from 'pondjs';
import { Charts, ChartContainer, ChartRow, YAxis, LineChart, Resizable, EventChart } from 'react-timeseries-charts';
import myJson from '../data/info.json';
The SO questions on this topic related to user-created components, not files installed via "npm install". I'm not sure if I installed it in the wrong place, or if React is looking in the wrong place. But pondjs should be available to React. The other libraries I've downloaded are. Why is this library different?
Don't use the -g flag when installing. The -g flag allows you to access the installed npm package via command line, but is not a part of your local project files.
If you need it both locally and globally, npm install it twice (once with the -g flag and once without).
If you are using Typescript, I don't think there's a type file for that package, so the compiler may give a warning even if the package is available.
I have started a React Native project from scratch and configured Flow.
When I run npm run flow everything works fine except a small problem with the react-native module:
Cannot resolve module react-native.
I am using:
"react": "16.3.1",
"react-native": "0.55.3",
"flow-bin": "0.74.0"
My .flowconfig is:
[ignore]
.*/node_modules/.*
.*/.cache/.*
.*/test/.*
[include]
[libs]
[lints]
[options]
[strict]
Tried with "flow-typed": "2.4.0" but didn't work.
I found the following issue but there aren't any solutions :/
You need to add a type definition for react-native.
Create a folder called type-def-lib in your project root and inside create a file called react-native.js with these contents
declare module 'react-native' {
declare module.exports: any
}
Then in your .flowconfig add that folder under libs:
[libs]
./type-def-libs
Now yarn run flow should produce no errors.
In the latest version flow-bin (0.157.0), this problem can be resolved by removing .*/node_modules/.* from [ignore]
