Cannot build APK with python3crystax and flask - conflicting dependencies

@kchomski commented on Wed Mar 01 2017

Hi,

It’s not possible to build APK when python3crystax and flask are both in requirements (or maybe I am doing something terribly wrong). From what I can see the problem comes from conflicting dependencies in recipes: flask depends on (python2 OR python3crystax) AND setuptools, but setuptools depends only on python2, which conflicts with python3crystax.

This is an issue with python-for-android itself. I’m moving it to the proper project.

Same issue here being caused by the requests package pulling in python2.

Closing as stale, this may well have been fixed by all the changes since it was raised.
