Expo Cannot Find Module after reinstall

Question

I'm having issues getting expo to start. It tries to open dev tools and dev tools will not open and gives me this error:

Cannot find module 'C:\Users\charl\AppData\Roaming\npm\node_modules\expo- 
cli\node_modules\@expo\image-utils\build\index.js'. Please verify that the 
package.json has a valid "main" entry

This is for a react-native application, using NPM, Node, a Windows 10 machine.

I've tried reinstalling expo with npm and yarn, but i cant get it to work. I looked and saw in the package.json file the 'main' key has a value of 'node_modules/expo/AppEntry.js'. Before this happened i was having trouble with expo that it told me that expo cant be recognized so i messed around with environment variables until it worked. Now this. Thank you guys for any help

Solution 1

Try running

npm install -g expo-cli --force

Solution 2

Was having this same issue when using Windows Powershell or CMD.exe. Was able to get passed it by using Git Bash. Try running npm install -g expo-cli from a MINGW64 terminal (ex: Git Bash)

Delete node_modules and package-lock.json, run npm install again.

I tried that, no luck. Uninstalling and reinstalling with npm and yarn doesn't work either

Is this the sequence of execution you've executed? expo init youproject => cd youproject => expo start
