Actual Behavior

Fails with this:

After dropping into an interactive terminal afterwards, it turns out that the prefix line of /home/node/.npmrc is missing. I don't know why, but my system seems to be removing it at some point.

As a fix, I've defined npm's prefix with an NPM_CONFIG_PREFIX environment variable instead, as per this docker-node guide. This has solved the problem and made the tests pass as expected.
