can't add a non pypi published package as a git package

[tanj]

I have a non-published git project that I'm using in a script. I've done some digging into the source and from what I can tell the reason is that it can't find the package version in pypi.

pyflow 0.2.9

Steps to reproduce

1. pyflow new project_name
2. Set dep

[tool.pyflow.dependencies]
swissarmy = {git = "https://github.com/tanj/swissarmy.git"}

3. pyflow install
4. Can't get version info for the dependency swissarmy. Is it spelled correctly? Is the internet connection ok?

The only place i can find that error string is here So it seems to me that the call to get_version_info fails (because this package isn't in pypi)
