npm run build error

I'm pretty sure the problem is that you have webpack installed in /Users/home/node_modules. I'm guessing that's by error, and you should probably remove the /Users/home/node_modules directory.

I'm going to close this issue, but feel free to comment if you have further questions.

You can try this also it's worked for me
go to your package.json
replace "react-scripts": "whatever ver u got" to "react-scripts": "1.1.4",
then run npm install, after that npm start

I have the same issue:

▶ npm ls webpack 
[email protected] /Users/yeven/projects/foo
├─┬ @storybook/[email protected]
│ ├─┬ @storybook/[email protected]
│ │ └── [email protected]  deduped
│ └── [email protected] 
└─┬ [email protected]
  └── [email protected] 

Unsure how to solve it

For me, delete the node_modules didn't work. So I had to put "SKIP_PREFLIGHT_CHECK=true" in the '.env'.

I first globally uninstalled webpack (npm uninstall -g webpack) and then globally reinstalled webpack 4.29.6 (npm install -g [email protected]). Next I deleted any node module which started with the word webpack in the directory C:\Users\MyUserName\node_modules folder but left all other packages untouched. This corrected to issue. I still have webpack installed in my AppData folder and in the programs folder. Using Windows 10, node 10.16.0, npm 6.9.0. Just a slight tweek on the answer given above. I spent three days on this issue so I hope it helps!

I should probably add that this is actually a react-scripts bug. You might consider reporting it there: https://github.com/facebook/create-react-app/issues/new

Good luck!

Thanks! I deleted the node_modules dir as you said and it worked perfectly.

[tomluo5]

Thanks, I deleted the node_modoles after success!

I had the same issue as yairEO where I was using several linked react-app libraries. I was able to resolve it by deleting all my project node_modules (and the symlink directories in my %AppData%\npm\node_modules).

i have executed all the steps but none worked for me

[rmille4612]

unnatikala05.... react is very moody. Doesn't seem to matter whether you're install on Mac, Windows or whatever. I've found you usually have some configuration tweaking to do after you first install it. Also, Facebook is constantly providing updates for newer versions of react. When you run npm create-react-app or npm init react-app you are installing dependencies from online repositories. If an update was placed there which incompatible with your installed libraries you'll need update your version npm. If your using windows that will likely mean literally removing and reinstalling the new version of NodJS from their website. Debugging can be frustrating at best. If you can provide more information about what errors you're receiving, and what code your running, I can try to help. Is it the same code in this repository? Or from another?
