Error: Cannot find module 'react-dev-utils/getPublicUrlOrPath'

Question

I have a React.js app which I've deployed on Heroku. Then I have this message:

Browserslist: caniuse-lite is outdated. Please run next command npm update.

So, I run npm update and npm audit fix. When pushing to Heroku again, I get this err :

Error: Cannot find module 'react-dev-utils/getPublicUrlOrPath'

This is what I got when running git push heroku master:

Solution 1

try using

npm install --save-dev react-dev-utils

it worked for me every time

Solution 2

While not on Heroku, I also had a similar issue with the same getPublicUrlOrPath error. I tried npm-install multiple times and got a 404 error from a bad dependency, so I deleted it from package.json, removed the file package-lock.json, then ran npm install --save and all worked fine afterwards.
