Pin setuptools to <36.1. #63

Closed fschulze closed 7 years ago

Upgrading further causes Pillow to fail to install. This may be caused by the inability of setuptools to install/upgrade itself anymore.

There was a temporary condition (for a few versions recently) where setuptools had a bug with install_requires that would have prevented a self install, but those issues should have been corrected and setuptools should once again be able to upgrade itself. You shouldn't have to pin to old versions.

I see the same problem. Building Pillow on Python 3.3 still works, but 3.4 fails. We use easy_install here, and even just asking for the help fails with this traceback:

$ /usr/local/pythons/parts/opt/bin/easy_install-3.4 -h

I am trying the fix from @fschulze now.

Well, the fix from @fschulze should work for the wrong reasons … I guess.

mauritsvanrees commented 7 years ago

The fix works for me, so I will merge it. We can always try to come up with something better.

It would probably be better to not do anything with easy_install anymore, although it is good that the script is still there.
