📄 Description

Running pip install on requirements.d/all.txt (in this example invoked by prod.txt) yields following error, while using pip 1.5.6 (python 3.4).

pip install -r requirements.d/prod.txt
Exception:

ValueError: ('Expected version spec in', 'django~=1.11.0', 'at', '~=1.11.0')

Changing the operator ~= to the accepted operator >= [0] fixes this problem.
