Something went wrong during the installation.

I am hitting this as well. I'm pinning to 23.1.0 for now as a workaround. Of interest, it seems to only affect python 2 (we were doing installs of python packages in an ubuntu 14.04 docker container and the python 3 ones worked fine).

[vadimkry]

yep. 24.0.0 also getting this

[anthrotype]

Could it be related to this? #624

[aabes]

our workaround was to:
Change L11 of "/usr/local/lib/python2.7/dist-packages/setuptools/extension.py

   < from . import msvc9
   > from . import msvc9_support

@anthrotype - I'd vote for - it's related ;)

[JGoutin]

I fixed this.
I anyone with this error want to check it now with the updated version for the PR #627 and report here if fix work. Thanks.

[boazin]

@JGoutin - any ETA on the official version to working again?

[JGoutin]

@boazin I don't manage this project, I am only a contributor.

@JGoutin - I checked your Fix on Linux 14.04.1-Ubuntu with python 2.76.
I'm not getting the exception "KeyError: 'processor_architecture'" but I get the following exception:

A simpler workaround (while waiting for pypi to be updated) could be to:
export processor_architecture=‘'

prior to attempting to install.

tested on python 2.7.6 (but with somewhat dated get-pip.py)

Unfortunately, I'm not in a position to test the patched version :(

[JGoutin]

@beckmani Thanks for reporting.

Six seem to not correctly raise Import error when importing winreg. I tried another strategy : disabling this module if not on Windows.

Patch updated.

[beckmani]

@JGoutin - There is still exception. See msvc.py line #336

[JGoutin]

@beckmani Thanks

I updated.

[beckmani]

@JGoutin - This time it worked. Thanks. :-)

[JGoutin]

@beckmani Nice ! Thanks for your tests !

Fixed in #627 and release pending for 24.0.1 release.
