Cannot find module '/src/bin/www' - Docker and Mean Stack - node.js

Question

I'm having issues creating my first docker container. I keep getting an error saying Cannot find module '/src/bin/www' when I enter docker-compose up In the package.json file I tried "start": "node /bin/www" and "start": "node ./bin/www" but same issue. Also the first time I ran it, it took about a minute, but ever since that when I run it, it throws the error within seconds. Don't know if that's relevant.
