Import Error: No module named AppKit

I use Mac OS X Lion and Python 2.7. I am new to python. Can anyone tell me how to import AppKit and PyObjC to Python. But i get the errors when trying to import Import Error: No module named AppKit or 'Import Error: No module named PyObjC.

Trying easy_install does not help either.

What can i do to import these 2 modules?

If not already installed, install pip by running:

sudo easy_install pip 

Then run:

## install for all users sudo pip install pyobjc 

or

## install for current user only pip install pyobjc --user 

^{NOTE: the general recommendation is to avoid using the system python, and use instead a user-maintained version, for example installed via brew install python3, macports, conda or whatever you already use for third party dependencies.}

If you're on Mac it could be you're using the incorrect pip version, try sudo pip3 install -U pyobjc that solved it for me.

This a good guide on how to install PyObjc:

When I was trying to install PyObjc I found it quite hard, but after a while, (and lots of google searches) I got it working.

Edit

I've found a more modern guide on how to do this. Download the templates and put them into your ~/Library/Developer/Xcode/Templates/ directory, and everything should work correctly.

If you are using PyCharm, you should install PyObjC package manually within it because of venv I guess. This was the only working solution for me.

In my case none of them worked. I was using Anaconda in my mac, later I discovered that the main issue with the Anaconda. Then I installed PyObjC with it's all supporting libraries inside Anaconda in a specific Environment.

I run the command line by clicking the Environment play icon and run my script.

It worked without any issues :)

If you've tried:

sudo pip install pyobjc

And it still isn't working then you may have at some point in the past accidentally installed an incorrect AppKit. Run:

sudo pip uninstall appkit

And then try

sudo pip install pyobjc

again. The issue I faced was that the other appkit was lowercase so wasn't recognised (and was the wrong package) but it was preventing pyobjc from installing the correct version of AppKit.
