ImportError: No module named decorator

[rockobonaparte]

I noticed this in the most-recent PyPI releases (0.12.2, 0.12.6):

Win10 with 64-bit Python 2.7.15, pip 10.0.1, pinject 0.12.6:

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in c:\users\SCRUBBED\appdata\local\temp\pip-download-xvd2h3\pinject\

The same line fails with the same error on Ubuntu 16 using 64-bit Python 2.7.15rc1, pip version 9.0.1, trying to download 0.12.2.

I download the module to convert it to a distribution-specific package for internal distribution. The pip download command itself is failing.

Version 0.10.2 downloads fine and I've updated my software's setup.py to be bound to it instead of trying to acquire the newer versions.

Can you try to install the decorator module manually then try again?

I think it's because we did not install the dependency of the decorator module.

I never got a notice on this so I didn't know you even responded. I actually came back to report this again because I forgot I had brought it up!

If I manually specify decorator, it looks like it does install and run with 0.12.6. A problem here is that I am using it in my own package, and I have to put it in my own package and hope it gets fetched first.

I think the problem is that setup.py is trying to fetch version information from inside pinject, which has an init.py that will try to import decorators. If you can split that off then I imagine it would stop cropping up.

The main problem here is if I make pinject a dependency for another Python package, pip will run setup.py and fail to find decorator--even if I specify decorator as a dependency in my own package--because pip hasn't actually installed it yet.
