Install git python library through python regardless of OS

Question

I have developed a tool that my team can use after running the setup.py script. The tool requires this library: https://github.com/c2nes/javalang

How can I make my python setup script install this library on their computer regardless of what OS they are on. They can't run my tool without that library (Some people are on windows, mac, and linux.)

Why not include it as a requirement (install_requires) in your setup.py? — jonrsharpe

@jonrsharpe This is my first time doing this, I didn't even know about the requirements.txt file for specifying requirements and then feeding it into pip install. I didn't know you could do that - that's cool. But what if they don't have pip? — Ogen

...then they can install pip? It comes with most versions of Python (3.4 onwards), or you can run get-pip.py. — jonrsharpe

pip can install projects on Github as a dependency too!

All you need to do is, in your requirements.txt, add a line like following:

..
git+https://github.com/c2nes/javalang.git

then install the dependency using:

$ pip install -r requirements.txt

What you are looking for exists on PyPI. Instead of git+https://.. line above, just say: javalang. Oh and BTW, unless they are running old versions of Python, they should already have pip installed. If they don't use your operating systems package manager or get-pip.py as you said.

What if they don't have pip? Is that going to be a problem.

It's on PyPI, no need to hit GitHub: pypi.python.org/pypi/javalang

So you're saying I can just say python get-pip.py if they don't have pip and then just run pip install javalang? How can I determine whether or not it's necessary to run the first command. I.e., maybe they already have pip.

@jonrsharpe: I assumed it didn't exist on pypi. I'll edit my answer. Thanks!
