Happy to open an issue, but any plans on supporting git+ssh urls? For work projects, we have some modules installed via git and when I tried to install, I got the same error described here: https://github.com/alexanderGugel/ied/issues/2
+1 here, git+ssh and git+http(s) are essential imho... its' the easiest way to sidestep the need for an npm server for some internal projects/libraries.
Very promising project!
