NPM install/start Errors

I can't make an npm install or npm start command. When I try npm install the console returns:

undefined postinstall C:\Users\Aristophanes 
> cd packages/react-error-overlay/ && yarn build:prod  
bash: line 0: cd: packages/react-error-overlay/: No such file or directory 
npm ERR! code ELIFECYCLE 
npm ERR! errno 1 
npm ERR! undefined postinstall: `cd packages/react-error-overlay/ && yarn build:prod` 
npm ERR! Exit status 1 
npm ERR! 
npm ERR! Failed at the undefined postinstall script. 
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

Firstly, I'm not really sure why it's looking for a packages/react-error-overlay/ directory, but I think the console might be referring to this directory on my computer at

C:\Users\Aristophanes\create-react-app-next\packages\react-error-overlay

As that's the only react-error-overlay directory with the packages/ prefix in its path. If I open that directory in cmd and try npm start I get this error:

> [email protected] start C:\Users\Aristophanes\create-react-app-next\packages\react-error-overlay 
> cross-env NODE_ENV=development node build.js --watch  

bash: cross-env: command not found

npm WARN Local package.json exists, but node_modules missing, did you mean to install?

Any ideas how I could fix this? Here is my package.json file:

1 Answers NPM install/start Errors

  1. npm start does not work because you do not have required dependencies. cross-env: not found
  2. Share your package.json so we can define the real issue.
  3. Answering to your question

    Why it's looking for a packages/react-error-overlay/ directory?

    Seems that you have postinstall script. Read more about pre and post hooks here: https://docs.npmjs.com/misc/scripts


P.S. With invalid postinstall script in package.json you should get next error:

error Failed at the [email protected] postinstall script.

Seems that you removed name and version form package.json, that is why your error is next:

error Failed at the undefined postinstall script.

That undefined in logs can confuse you
