Error with setup.py install_requires?

[leblancfg]

Expected behaviour

I can pip install opencv-python without a hitch on my dev box, but am running into problems when setup.py's install_requires is trying to do it. I'm assuming the issue lies here, perhaps some of you are familiar with the error message?

Actual behaviour

Processing dependencies for autocrop==0.1                                      
Searching for opencv-python            
Reading https://pypi.python.org/simple/opencv-python/                          
No local packages or working download links found for opencv-python            
error: Could not find suitable distribution for Requirement.parse('opencv-python')                                                                             

Steps to reproduce

• example code

setup(install_requires='opencv-python')

in my package's setup.py, when running python setup.py install

• operating system

  • Manjaro Linux

• architecture (e.g. x86)

  • x86

• opencv-python version

  • Latest (any)

Use pip install .

I'm pretty sure that setuptools doesn't support / understand wheel dependencies.

Ah, that explains it, thanks. Using pip install . instead of python setup.py install seems clear now, but totally didn't at the time. The joys of Python packaging 😄
