如何安装 github zip 文件与 pip 和 setup.py 来自 requirements.txt？

Question

I am working with a library called lief which due to it lacking full python 3.7 support from pip, I need to install it from the following link https://github.com/lief-project/packages/raw/lief-master-latest/pylief-0.9.0.dev.zip .

The issue I am having is that it works fine when i do pip install https://github.com/lief-project/packages/raw/lief-master-latest/pylief-0.9.0.dev.zip , it works fine, but if i put that link in my requirements.txt file, it fails to install in travis with the error

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

Most of the examples I have seen about requirements.txt and github link points to a commit hash. How can I install a github zip file from requirements.txt so when i run pip install. , I am not getting the above mentioned error?

I should add that if i do pip install -r requirements.txt , it works fine, but if i do pip install -e. which uses setup.py, it will fail

As a stop gap measure, I am doing the following in my setup.py for anyone that runs into a similar problem. This works with pip install.

from pip._internal import main as pipmain
pipmain(['install', 'https://github.com/lief-project/packages/raw/lief-master-latest/pylief-0.9.0.dev.zip'])

But would really like to know if there is a more elegant way to do this using pip install. where the link is in requirements.txt .
