Installing packages that references an git repository in requirements.txt fails.

[AraHaan]

Here is an example package's reuirements.txt and setup.py that is hosted on github only that fails every time it is attempted to be installed using pip.

Also happens when running setup.py directly without pip.

requirements.txt:

regex
aioredis
colorama
pycares
discord.py
aiohttp
PyNacl
cchardet
cffi
multidict
yarl
discord.webhooks
TinyURL3
consolechange
git+https://github.com/AraHaan/dbapi.git
youtube_dl

setup.py:

In interactive mode it works as expected (without executing setuptools) but in pip for some reason it fails when it should not fail. Unless setuptools cannot process the vcs's properly that pip gladly supports and is able to take in and process just fine.

install-requires takes a list of names with optionally versions. If you want to pass in a link, you have to use dependency_links.

Furthermore, don't load a requirements.txt file. I know this is commonly done but this file is not for installation dependencies but instead for listing packages one wants in an environment.

[AraHaan]

As much as that is said I know of a few packages that use an requirements.txt file to install dependencies when you pip install it (discord.py being one of said packages).

I guess I could modify the code to where if it finds an git+ or whatever to remove it from the list and into another one. But it would have to know all possible svn's people can link or use on it.

Edit: here is my work arround setup.py.
