Error when trying to install package from github repo with submodule

Environment

• pip version: 19.1.1
• Python version: 3.7
• OS: Windows 10 x64

Description Pip is unable to install the package at https://github.com/pyminimp3/pyminimp3. There’s a permission error while cloning its submodule. Judging by Host key verification failed, it looks like git tries to use SSH to clone it when the initial command is requesting https.

Expected behavior Package is cloned and installed.

How to Reproduce Run the command pip install git+https://github.com/pyminimp3/pyminimp3

Output

C:\Users\admin>pip install git+https://github.com/pyminimp3/pyminimp3
Collecting git+https://github.com/pyminimp3/pyminimp3

I’m going to go ahead and close this issue due to a lack of activity/interest.

Trying to pass-through settings to git for all variations of submodules (https with auth, https without auth, https with custom certificate, ssh) would be a lot of work. I’m inclined to say that if someone actually wants this implemented they can open a feature request for it.

For the simple case here - if a user doesn’t want submodules requested with ssh, it is possible to use URL rewriting to force one way or another for all requests: git config --global url.https://github.com/.insteadOf [e-mail]:
