Problem

Everything has been working just fine, but after installing a new package docker stopped working as expected. Every time I run docker-compose up it fails with 'Module not found' error.
While npm start works perfectly fine.
I've tried quite a few workarounds found on the web:

• restart PC


• delete node_modules folder and run npm i again


• different combinations of npm install / --save / including --save in Dockerfile

It just doesn't work and I can't handle it on my own. Any ideas why this might be happening?

Update

Weirdly, but this code works. I'm a rookie in Docker, so I have no clue what's the difference

docker run -it 
 -v $PWD:/usr/src/app 
 -v /usr/src/app/node_modules 
 -p 3000:3000 
 --rm 
 prov-app

docker-compose up it fails with 'Module not found' error.

You need to rebuild your image to have that package installed. docker-compose build, and then docker-compose up

EDIT

Based on your update, I realize that the problem is your old node_module volume persisted between builds. Try docker-compose down -v before up.

Instead of:

volumes:
 - '.:/usr/src/app'
 - '/usr/src/app/node_modules'

Try:

volumes:
 - ./:/usr/src/app
 - /usr/src/app/node_modules
