Issue

As shown below, the git+https[...] package reference is interpreted as git instead of esgf-compute-api in this case.
I'm guessing the + leads to a space escape or something similar, but this is a valid method to reference/install a package.

The alternative (more traditional?) method is something like:

<package> @ <reference-url>

This invalid parsing is more problematic in cases where there are more than one git+https reference, as they are all regrouped under a common git package.
