How to specify a specific github repo version in requirements.txt?

Question

I want to be able to install a specific version of a github repo. I followed the instructions given here and my file requirements.txt looks as follows:

git://github.com/twoolie/NBT@f9e892e

I also tried the following versions:

git+git://github.com/twoolie/NBT@f9e892e
git+git://github.com/twoolie/NBT.git@f9e892e
git://github.com/twoolie/NBT.git@f9e892e

but in every case when I try to install the actual package, which requires the repository NBT from commit hash f9e892e, I get the error message

error in PyBlock setup command: 'install_requires' must be a string or list of strings containing valid project/version requirement specifiers; Invalid requirement, parse error at "'://githu'"

So how to do it correctly?

Answer 1

I solved the problem by adding the following argument to the setup method in `setup.py':

install_requires=['NBT@git+git://github.com/twoolie/NBT@f9e892'],

and using an empty requirements.txt file. With these setting the install of the specific version of the package did work finally.
