Cannot install nose without superuser privileges

Currently when I try to install nose with pip, I'm getting the following error:

$ pip install -U nose
Collecting nose

I'm unsure why pip is trying to write to /usr/local here. After asking on pypi, someone suggested it was due to this line in nose's setup.py file: https://github.com/nose-devs/nose/blob/master/setup.py#L109

FWIW, if I remove line 109 from nose's setup.py file, I'm able to successfully install.

Just encountered this problem myself, while installing something depending on nose. Took a while to narrow the problem down and find this issue.

Creating /usr/local/man myself resolves the problem, and the installer doesn't even create a file there. Not sure what's going wrong here that produces this behavior.

A fix for https://github.com/Homebrew/install/issues/109 will resolve this problem.

https://github.com/Homebrew/install/issues/109 is closed and won't be addressed.

resolving this problem will require either convincing the nose devs to put their man page in /usr/local/share/man or convincing the homebrew-core python formula devs to modify the behavior of pip to recognize attempts to write to /usr/local/man should end up in /usr/local/share/man

additional reports of this problem, all caused by nose:

I would suggest that nose not try to install the man page at all. If someone needs to package the man page for e.g. debian, they can do that manually.
