I'm trying to run react app I got this error:

☁  app [master] yarn start
yarn run v1.22.17
$ react-scripts start
node:internal/modules/cjs/loader:488
      throw e;
      ^

}

Node.js v17.0.1
error Command failed with exit code 1.

How do I download the app ?

npx create-react-app my-app
cd my-app
npm start

my stuff version

node -v v17.0.1

yarn -v 1.22.17

npm -v 8.1.4

I've tried every single thing in this but nothing worked for me

I was also getting this error, then I ran npm update and that seemed to clear up this error. But now I'm getting a new error about "no such file or directory, stat '/home//.steampath'"

Maybe that's just a separate issue with mine though, hopefully npm update works for you!

Edit: I was able to fix my "no such directory" error, it was caused by an issue with me trying to transfer a file from a different drive. I was able to resolve it. So unless you also have that same problem, npm update should fix it for you.

I had this issue, as well. I was able to get CRA to work by installing/using Node v16.13.1 via NVM. This is an issue with CRA depending on an old version of postcss-safe-parser referenced here.

First install NVM and then ...

nvm install 16

Make sure node 16 is being used by NVM and yarn start should work.
