Question or problem about Python programming:
I want to remove a Python installed in location that brew complains about, when I run brew doctor
What is the best way?
Here are more details / research:
The message from the brew git website:
I want to make sure I am not missing anything before I remove the extra python libary.
Specifically, I want to remove the entire Python.framework, those files located here.
/Library/Frameworks/Python.framework/
I have Python 2.7.5 installed natively with Mavericks that I’ll use instead – located in the path below. (The difference being — I believe — that its put in the root /System folder instead of the root /Library folder.) The good, native location is here:
/System/Library/Frameworks/Python.framework/Versions/2.7/bin/python
and I already installed python 3.x with brew install python3, which put it here:
==> Summary /usr/local/Cellar/python3/3.4.0 : 5076 files, 85M, built in 112 seconds
Can I just delete these files or are their consequences (beyond having to relink)?
/Library/Frameworks/Python.framework/
Here are steps to remove python from a stackoverflow question in 2010 and a similar question here
Is that approach still sound? Is there anything I should be aware of?
How to solve the problem:
I’ll self-answer. I went through steps and it’s straight forward. Pycharms (the IDE I’m use) automatically found the new libraries too. Here are the steps I followed to remove the extra Python libraries on Mavericks that were not native to it and not installed by brew.
Step 1:
The native Python 2.7.x version lives here /System/Library/Frameworks/Python.framework/Versions/2.7
(or 2.6, etc), so you can remove any Python that got installed elsewhere.
sudo rm -rf /System/Library/Frameworks/Python.framework/
Or, according to this article, you should brew install both python 2.7 and python 3.x,
and avoid using system python in Mavericks.
Step 2:
Remove python in Applications directory (the one where all your apps are).
cd into folder /Applications
and ls | grep Python
to see what have.
Then remove:
sudo rm -rf "Python 3.3"
Step 3:
>>> brew prune
sample output:
Pruned 0 dead formula Pruned 46 symbolic links from /usr/local
Step 4: Run steps recommended by brew doctor
sudo brew link python3
Sample output
Linking /usr/local/Cellar/python3/3.4.0… 19 symlinks created
