errorr installing pyobjc on Anaconda python on OSX

问题:

I have Python 3.3.5 :: Anaconda 2.1.0 (x86_64) on Mac OS X 10.10.2 with XCode 6.2 (6C131e) and pip 6.0.8

I'm trying to install PyObjC following the guide. However when I do

pip install -U pyobjc

I get the following error:

$ pip install -U pyobjc

Googling the error message, I found this, where it's marked as resolved so I'm not sure how to proceed.

回答1:

The problem with installing PyObjC 3.1 using Anaconda can be worked around by setting "MACOSX_DEPLOYMENT_TARGET=10.9" before running pip, as an example:

$ MACOSX_DEPLOYMENT_TARGET=10.9 pip install -U pyobjc-core
$ MACOSX_DEPLOYMENT_TARGET=10.9 pip install -U pyobjc

There will be a proper fix in pyobjc 3.2, but I don't know yet when that will be released.
