vsc-install asks for credentials when using tox

[wdpypere]

when running tests locally I get:

...
INFO: Searching for vsc-config>=1.31.0
INFO: Doing git clone from ssh://[email protected]/hpcugent/vsc-config.git to /tmp/easy_install-naixMB/vsc-config.git
Enter passphrase for key '/home/wdpypere/.ssh/id_rsa': 

I see no reason why vsc-install should even try to use my SSH keys or passphrases?

I'm not sure we can avoid this...

Maybe vsc-install should try using https:// before using ssh:// URLs?

@stdweird Thoughts on this?

[boegel]

the changes in #143 don't actually fix this, so re-opening...

This is still a problem, and it also happens when running python setup.py test in repos that depends on a private repo like vsc-config.

Two possible solutions are:

• manually installing the dependency that is hosted in a private repo into the .eggs.py2 or .eggs.py3 subdirectory, using PYTHONPATH=/path/to/.eggs.py2:$PYTHONPATH python setup.py install --prefix /path/to/.eggs.py2 --install-lib /path/to/.eggs.py2 (the --install-lib is important to avoid installing into a lib/python*/site-packages subdir in the .eggs.py2 dir)
• for reason just blasting away the .eggs.py* directory and just trying again seems to help too, but perhaps that's due to some caching mechanism, I don't understand how that would suddenly make the private repo accessible when it isn't before
