Installing package from github (git+ syntax) fails due to inconsistent internal identification

[classner]

• I have searched the issue tracker and believe that this is not a duplicate.

Make sure you run commands with -v flag before pasting the output.

Steps to reproduce

pdm add git+https://github.com/VLL-HD/FrEIA.git

Actual behavior

Adding the package fails:

# pdm add git+https://github.com/VLL-HD/FrEIA.git -v

Debugging

I started debugging this and found that pdm first identifies the package as :empty:... (as defined in requirements.py:136), but later somehow identifies the package actually as freia. Because of this inconsistency the depth is not correctly registered and the dictionary key lookup fails.

Give the name to it in command: pdm add git+https://github.com/VLL-HD/FrEIA.git#egg=FrEIA
