I was working with brownie and everything was working smoothly, launched my first useDapp app and it was a lot of fun. I wanted to see what truffle was about and installed it via npm and there were a bunch of warnings and it didn't seem smooth when it came to functionality so I might have installed it via yarn, expecting the package installer to fix things. It worked for a while then it started to timeout upon migration with tested code that used to launch perfectly fine? I thought it might of been a bug or some form of overlapping installation. I moved on to hardhat and installed it via NPM and it wouldn't compile, so I installed it via Yarn and it compiled fine. I went on to creating a new file and accidentally hit Esc when it was initializing a new file and setting the root. Somewhere in between there I tried to install the shorthand and it didn't work. It only opened a Windows help window instead of call hardhat when I typed hh --help. After that I couldn't call hardhat via yarn hardhat nor npx hardhat outside of the file....the file that previously wouldn't compile was still able to compile via npx hardhat compile?
It sometimes says "module not found", other times it says something about local installation.
I kind of got frustrated and wanted to play with react a little more and when I went to start yarn I got an error message. I followed the prompt and it didn't work, I googled it and had no luck with their common resolutions. I tried to upgrade eslint and even install 7.11.0 and it keeps saying I have version 5.16.0?.
EDIT: not sure if it is relevant, I tried to update my yarn to 1.22.17 and it said it did, although it says im running 1.22.15.

The react-scripts package provided by Create React App requires a dependency:

Don't try to install it manually: your package manager does it automatically.

Manually installing incompatible versions is known to cause hard-to-debug issues.
If you would prefer to ignore this check, add SKIP_PREFLIGHT_CHECK=true to an .env file in your project.
That will permanently disable this message but you might encounter other issues.
To fix the dependency tree, try following the steps below in the exact order:
1. Delete package-lock.json (not package.json!) and/or yarn.lock in your project folder.
2. Delete node_modules in your project folder.
3. Remove "eslint" from dependencies and/or devDependencies in the package.json file in your project folder.
4. Run npm install or yarn, depending on the package manager you use.
In most cases, this should be enough to fix the problem.
If this has not helped, there are a few other things you can try:
5. If you used npm, install yarn (http://yarnpkg.com/) and repeat the above steps with it instead.
This may help because npm has known issues with package hoisting which may get resolved in future versions.
6. Check if C:\Users\Nancy\node_modules\eslint is outside your project directory.
For example, you might have accidentally installed something in your home folder.
7. Try running npm ls eslint in your project folder.
This will tell you which other package (apart from the expected react-scripts) installed eslint.
If nothing else helps, add SKIP_PREFLIGHT_CHECK=true to an .env file in your project.
That would permanently disable this preflight check in case you want to proceed anyway.

Kind of embarrassing, the answer was in the error message.

Hardhat set root in the wrong directory and I ended up with a node_module folder in a parent directory that was messing things up
Reinstalled truffle globally via yarn add global truffle and it ran smoothly. Evidently, truffle acts up with certain NPM versions.
Hardhat doesn't seem to support global installations yet. Its been working fine being locally installed into each separate hardhat project via yarn add -D hardhat
I haven't been able to get the shorthand to work without invoking yarn first, such as yarn hh <command>

I have a problem that when I clone a Github repository that is older more then half a year I am not able to run it with neither npm start nor yarn start. I have been successful with one repository only and it was only a few months old. I think it might be because of the new React version. I am quite new to React so I don't know for sure.
I always get an error message that looks something like this

You have a node_modules folder in your user profile directory which shouldn't exist. Maybe you ran npm install <something> in your user profile once by accident without -g.
Delete c:\Users\UNION\node_modules and you should be fine.
Note that this was actually in the list of suggestions that you already got:

You wrote you tried the steps - next time it would be great if you could also include the results of these attempts in the question so we know what you tried and what effect it had. In this case, for example "#6: Yes, it is outside of my project directory, but I'm not sure what to do about it".
Quite new to react, and can not find an answer to the simplest of tasks. Just trying to clone a repo to my computer and run it. For example https://github.com/arnab-datta/counter-app .
I do npm install and npm start. But when I do npm start I seem to have dependency errors with a "babel-loader". It gives me the below list of steps to solve the problem, I went through them all and still no success. No matter what project I try to repo the error is always this babel-loader. I am new to react and getting very frustrated being unable to do the simplest of things.

I have tried following the steps suggested however none of this seems to works. I have also tried yarn add --exact react-scripts#3.0.1 and yarn cache clean
I fixed it!
So as the error shows, there is an existing folder of 'babel-eslint' somewhere higher up in my dependency tree. All I had to do was search in finder for that folder and then delete it, once done you can just 'yarn install' again and 'yarn start' then it should work :)
I have no idea where this other 'babel-eslint' folder came from btw...
I have an issue that I cannot solve.
I'm using ESLint in VSCode for my all projects.
Now I created a new react app but when I run it (npm start or yarn start), it throws an error.
React app use ESLint 5.12.5, is lower version of mine.
I tried following the steps in the suggestion but ... it's not fixed.
Can anyone solve my issue?
I tried npm uninstall -g eslint, npm uninstall eslint, npm i ...bla..bla, removed my ESLint extension in my VSCode, and re-created react app. But the error has not been fixed.
I checked eslint -v, it said 5.14.1, but in the error notice, vscode said version 5.16.0 is in node-modules ##.
This is full error notice when I try yarn start or npm start:
> homework02#0.1.0 start E:\Extenal Code\Hoc JS\ReactJS-iViettech\homework02
> react-scripts start

I just solved this issue, the error says:
The react-scripts package provided by Create React App requires a dependency:
"eslint": "5.12.0" (in my case "^5.16.0")
but also says you have another version at package.json that's
E:\Extenal Code\Hoc JS\node_modules\eslint (version: 5.16.0) in my case was 6.1.0
so my solution was:
I searched for the dependency called eslint and updated the version similar to Create React App expected "eslint": "^5.12.0" (in my case "eslint": "^5.16.0") at package.json
Then run npm install and now you can run npm start... if you have troubles with slint-plugin-import just update the version as well, additional you can try installing locally instead of global with --save.
I believe this is an ongoing issue with create-react-app and eslint as detailed at:
https://github.com/wesbos/eslint-config-wesbos/issues/17
There are a number of suggestions there, though I'm hoping they will put a more permanent fix in place.
In my case it works like below:
Create New Project or clone form vcs.
Create .eslintrc.json file by yourself. Do not use Ctrl+Shift+P ->Eslint:create eslint configuration.
Try searching for eslint and change the version to the required version in the package.json file of eslint. 5.12.0 in your case.
Just try clearing cache and everything will come into normal usage you can use npx create-react-app project-folder-name, this worked for me.
Use this cmd in your terminal
cmd -> npm cache clean —force
there is different process to make it work just have to follow two installations for the future projects too if you like you can use this too and can work for your projects, cmd line is mentioned below :
cmd 1-> create-react-app my-app --scripts-version #nomoreanalog/react-scripts-eslintless
cmd 2-> npm install --save-dev babel-plugin-styled-components
