vuejs application does not run with dockerized npm

Question

I'm trying to set up a repeatable build-environment which does not mess with anything on the local machine. For that I decided to use docker to wrap the npm and vue cli. Everything runs on the machine where I first ran the vue quickstart command.

But when I take a fresh clone from the repository on another machine, I get the following error after running the setup process:

$ ./npm run dev

> [email protected] dev /data
> node build/dev-server.js

module.js:472
    throw err;
    ^

It says that details are in /data/npm-debug.log but I can't see that file either. So both the build folder and npm-debug.log seem to never appear on the mounted volume. I guess something with my docker setup is not quite right. But I don't know what.

To reproduce the following error run the following:

NOTE You need to hav "fabric" installed for the 4th step. If you don't have it, look at the contents of fabfile.py, it's really easy to understand and run the tasks manually.

NOTE2 If you don't have python 3 with "pyvenv", the fab develop task will fail on the last step of the develop task. You can ignore this for this docker/npm issue as the Python portion is not needed.

git checkout stackoverflow-2017-06-17
fab develop
cd frontend
./npm run dev

The "build" folder was in the .gitignore file. It should not have been.

I mistakenly took that folder as a folder with built artifacts while it contains configuration files for the build process. Hence it should not be ignored and must be part of the repository. I have since added it to the repository and the process has become repeatable without problems.
