pip 10 is unable to install from non-editable VCS URLs

See original GitHub issue

Pip version: 10.0.0
Python version: 3.5.4
Operating system: Linux

Description:

I’m trying to install a package from Git.

What I’ve run:

$ pip3 install git+ssh://git@example.com/mypackage.git#egg=mypackage

Building wheels for collected packages: mypackage
Exception:
Traceback (most recent call last):

AssertionError: No source dir for mypackage from git+ssh://git@example.com/mypackage.git#egg=mypackage in /home/p/local/lib/python3.5/site-packages

If I uninstall the package and then install, it works. But it continues to fail when trying install again.

@pradyunsg I didn’t do extensive testing, but #5280 resolves the issue for our case.

In case others are also debugging this. I’ve narrowed down the two paths, first install and reinstall, to the difference in the results coming out of the resolver’s _get_abstract_dist_for. Prior to that call both paths have <InstallRequirement>.source_dir == None. After this call, only the first install path has a source_dir set to something other than None. I’m guessing this is because it needs to go off and fetch the source during the first-install, but not on the reinstall.

… I could be off in the weeds though. It is my first time looking at this code. 😕
