It looks like we can't handle the version number of your npm install. Are you using a pre-release or compiled from source version of npm? What is the output of npm --version? Can you try with a release version of npm (e.g. 6.4.1).

I am using the latest version from Node's site.
Should I downgrade to their LTS version?

# npm --version
6.5.0-next.0

[Synergyst]

Alright..

It seems to be working now.

I'll close this issue here in a bit if it compiles correctly.

We can fix it to work with the latest NPM version. But at least there's a workaround in the meantime.

Resolved temporarily (until changes are commited) by using the following version of NodeJS: v10.15.0 (https://nodejs.org/dist/v10.15.0/node-v10.15.0-linux-x64.tar.xz)

Should be easy to fix.

Fix cherry-picked for v2.4.6.
