Unable to install React application dependencies because the node_modules folder is missing and an error is thrown

Question

I am trying to install a React app but it cannot be installed, it always gives the following error and the entire node_modules folder disappears.

npm ERR! code ERESOLVE
npm ERR! ERESOLVE unable to resolve dependency tree
npm ERR!
npm ERR! Found: react-scripts@5.0.1

And it won’t let me install react-app-rewired

I tried using --force and --legacy-peer-deps but no luck, I've been stuck here for 3 hours and can't solve it from anywhere. Also tried clearing cache and reinstalling, but no luck either.

For some private packages, I used npm auth and $NPM_TOKEN, but I still get the following error:

npm auth

Answer 1

Solved the above problem using the following methods:

1. Delete and re-clone the project
2. Created npmjs token for custom private package and updated it in .envrc file.
3. So after npm i failed, npm i --legacy-peer-deps was used, before running npm cache clean --force

Wow! All dependencies are installed

The mistake I made initially was trying to use npm auth, but that wasn't actually needed because npm would pull the code from the .envrc and .npmrc files Get it

So if you face similar difficulties, please try these steps
