I was going to redeploy a web app, so I was trying to run yarn build, and it runs into this error.
I am using Ant Design, I also did a yarn eject before, after a search through google still no luck, any encountered this is an error before? Any tips on solving it? thanks!
yarn run v1.22.0
$ react-app-rewired build
Creating an optimized production build...
Failed to compile.
./node_modules/antd/es/style/index.less

Even I faced the same issue. My problem was I mixed up with Ant Design versions. Ant v4.x was released recently, so I used components without checking the version. So, try using components of same version and see if it works!!.
Okay, so for anyone who might face the same issue, you need to remove react-rewire and do the migration from V3 to V4 shown on Ant.Design Doc, then should be fine

I tried to install styled-components for my React app with the following command npm install --save styled-components.
Before I did this, my server started up just fine with npm start.
After install, React tries to start up the development server but it stops and returns the following errors:
cacheEntry.sizeOnlySource = new SizeOnlySource(size);
TypeError: SizeOnlySource is not a constructor
at updateFileWithReplacementSource (project-directory/node_modules/webpack/lib/Compiler.js:756:37)

Initially, I tried uninstalling the styled-components package. Same errors. Then, I tried updating webpack with npm update webpack.
I googled the errors but they were all for problems that seemed unrelated or that are now fixed.
Support Webpack 4.29.0 breaking change
output.futureEmitAssets option breaks compatibility with source map upload plugins
library target umd - Uncaught TypeError: x is not a constructor
I did come across a post on Stack Overflow explaining that --save is no longer necessary as of npm version 5.0.0. Perhaps it's the source of the error?
Note that I installed the styled-components package on a separate branch of my project, but the server still won't start when I switch to the main branch and I'm getting the same errors.
Honestly, I have no idea what's going wrong or how to fix it. Any help or guidance would be greatly appreciated.
Edit: before the Starting development server... line I get after running npm start, there's some kind of message about webpack being deprecated. I hadn't noticed that before, but it flashes by too quickly for me to read it and I can't scroll up to see the message. I created a new React project from scratch to see if the server would start. It does, but I'm still getting the aforementioned messages.
I forked react-select to add a couple of features that the current react-select doesn't have. I created a branch and committed it to my forked project. Now, i want to use the forked project.
Ive tried installing the forked react-select repo the following ways with out success.
yarn add #react-select/monorepo#<GithubUsername>/react-select#head=<Name of branch>&workspace=react-select
yarn add #react-select/monorepo#<GithubUsername>/react-select#commit=<commit#>&workspace=react-select
yarn add #react-select/<github url>#head=<Name of branch>&workspace=react-select
I've tried it with ssh, with git+. with everything that the yarn website says and all i get is react-select installed but i don't see the code changes thats in my branch.
I've also tried to install the react-select package that the monorepo uses, but i get the following error
yarn add react-select#https://github.com/<USERNAME>/react-select/tree/master/packages/react-select
Failed with errors in 0s 290ms

i am using yarn 2.4.2
Has anyone dealt with this?
Any solution besides just copying the folder and installing it from a file path?
I had the same issue but upgrading to yarn version 2 worked. The following syntax for adding workspaces only starts working from yarn 2 on:
yarn add #react-select/monorepo#<GithubUsername>/react-select#head=<Name of branch>&workspace=react-select
I just created an Umi Ant Design Pro project but when i run my project (yarn start),i am getting the following error:
Steps taken to resolve this issue:
1:installed rc-textarea:
yarn add rc-textarea
2:stopped my server and ran yarn again in my terminal
3:then ran yarn start to start my server and still got the same error although my terminal this time stopped displaying the error i keep getting in my browser as seen below:
Step4:I then did some Research and came across this link
Git Memory Blog
But the path : ./node_modules/antd/es/input/TextArea.js does not exist in my project.
I also found a github link with a similar issue:
GithubIssue
Other solutions did not work so i tried wbcs's solution:
yarn cache clean
yarn install
But the error is still eminent.
My inspection window indicates that this is a possible webpack issue:
How do i resolve this?
Try removing .umi and node_modules folders, and then start this project again.
I am trying to start up a react app. After cloning the code from github, running yarn install I ran yarn start and got the following error:
yarn run v1.22.10
$ cross-env HTTPS=true react-scripts start
Unexpected identifier
error Command failed with exit code 1.
info Visit https://yarnpkg.com/en/docs/cli/run for documentation about this command.
The authors of the app don't know what might be wrong (it's working for them). I tried creating another app with create react app and that started up fine for me. I am not sure where to start looking as there is no indication as to where the "unexpected identifier" might be located or what it might be. Any ideas on what I might want to check or try? I am on MacOS Catalina.
I figured it out eventually. I tried running build and it failed on syntax error in one of the .js files (a missing comma). Once that was fixed the start ran too. If the start command returned the same informative error the build did it would have saved me hours :)
React v 15.4.0 was released this morning and seems to have included a change that broke react-tap-event-plugin v1.0.0 producing this error:
$ npm build
> myProject#0.1.47 build /.../myProject
> node scripts/build.js
Creating an optimized production build...
Failed to create a production build. Reason:
Module not found: Error: Cannot resolve module 'react/lib/EventPluginHub' in /.../myProject/node_modules/react-tap-event-plugin/src
(note: I cleaned up the output a little)
According to THIS react-tap-event issue log version 2.0.0 of react-tap-event fixes the build problem. However, material-ui is still using react-tap-event version 1.0.0. What are the options here? The only options I can think of are:
Downgrade react and other packages as described in the link above
Wait for Material-UI to upgrade to react-tap-event 2.0.0
Any other solutions here? I'm pretty much dead in the water if I wanted to use react 15.4.0, as far as I can tell.
Almost make sure you update the react-tap-event-plugin to the right version of react.
material-ui version 0.16.3 is released to address the problem.
I had the same problem. I resolved it by going through next steps:
- delete `"react": "{your-version}"` line from package.json;
- delete node_modules dir;
- run `npm i`;
- run `npm i react --save`.
in React 16.4 removes a lot of internals (#121) this plugin depends on and will break the plugin.
https://www.npmjs.com/package/react-tap-event-plugin
as solution with new release of React uninstall thia plugin and deleted any imports and uses from source Reaction Commerce: TypeError: require(...).__SECRET_INTERNALS_DO_NOT_USE_OR_YOU_WILL_BE_FIRED is undefined
and
Is react-tap-event-plugin still needed in 2018?
i removed react-tap-event-plugin from my reactjs project. it work for me
