Problem building package for Django 1.9

[ivoflipse]

I'm trying to build a package for Django 1.9. I created a recipe using conda skeleton pypi django and left the recipe untouched.

Then when running conda build django on a Windows 7 PC with Miniconda 2 (64 bit) I get the following error:

This problem was introduced in the latest release and the proposed solution was to update to the latest version of setuptools, which I'm using.

It seems related to the pyc_compilation, which tries to compile a .py file which contains invalid Python code. So I guess my problem is related to this issue.

What would be the best way to fix this?

[jakirkham]

Have you tried setting PYTHONDONTWRITEBYTECODE? I think that would be worth a shot. Could be tacked on in the build.sh and bld.bat.

[jakirkham]

FWIW, this problem does not occur with the most recent Django 1.9.2.

I also stopped encountering this problem for Django 1.9.7. Not sure why... I guess we can close it.

[msarahan]

Since I have not intentionally fixed this, I'm reopening. Glad you're not having trouble in the meantime, though.

[msarahan]

As of the 1.21.11 release, we now try to compile, but do not crash on failure. This was added by @minrk in #1146. I think this closes this issue - but please reopen or open a new issue if we need further discussion.

Thanks @msarahan!
