Homebrew brew doctor warning about /Library/Frameworks/Python.framework, even with brew's Python installed
Question:
When I ran Homebrew’s brew doctor (Mac OS X 10.9.2), I get the following warning message:
Warning: Python is installed at /Library/Frameworks/Python.framework
Homebrew only supports building against the System-provided Python or
a brewed Python. In particular, Pythons installed to /Library can
interfere with other software installs.
Therefore, I ran brew install and followed the steps provided in the installation’s caveats output to install Homebrew’s version of Python. Running which python confirms that Homebrew’s version of it is indeed at the top of my PATH. Output is /usr/local/bin/python.
Despite all this, when I rerun brew doctor, I am still getting the same warning message. How do I suppress this warning? Do I need to delete the /Library/Frameworks/Python.framework directory from my computer? Am I just supposed to ignore it? Is there a different application on my computer that may be causing this warning to emit?
Note that I don’t have any applications in particular that are running into errors due to this warning from brew doctor. Also note that this warning message didn’t always print out when I ran brew doctor, it was something that started to appear recently. Also, I am using Python 2.7 on my computer, trying to stay away from Python 3.
Answers:
I had the same problem. When I upgraded python3 through Homebrew, I started getting this:
-bash: python3: command not found
I had the same conflict with Python somehow being installed in /Library/Framework/Python.framework. I just did a brew link overwrite and everything is working fine now. There is some info about what to do with the Python version in the /Library/Framework/Python.framework here.
I guess you could try deleting that version as the link suggests, just make sure that version isn’t being used. When I got into the Python.framework directory I was seeing some EPD version of Python, which I think is Enthought. You could delete it, but I if it isn’t causing you any problems besides the unsightly Homebrew warning message, then I think you should just ignore it for now.
Update:
I did delete the Python.framework directory which, through some poking around inside that directory, I started seeing a few old versions of Python that I didn’t install with Homebrew. One was from Enthought, and another was a distribution of Python3.3. I think some of these installs in the Framework directory are user installs. I installed R on my system, and there is also an R.framework directory, so I think most of these are user installs. After I deleted the directory, I just had to call brew prune to remove the old symlinks. I checked both brew versions of python 2.7.6 and 3.3.4, and they seem to be in good working order with all of my installed packages. I guess I leave the decision to remove that directory, or python version, to your discretion.
I also received this message.
Something, sometime installed
/Library/Frameworks/Python.framework
on my machine (the folder date was about 4 years old).
I’ve chosen to remove it.
Please note that the Apple provided framework lives in
/System/Library/Frameworks/Python.framework/
per this thread, enter this command:
sudo rm -rf /Library/Frameworks/Python.framework
because there are multiple installations of Python on your computer, and this removes the one that may cause additional problems in the future.
Removing directories manually can be a nightmare, but fortunately ‘brew’ can take care of that. Once you are done with the removal, put this:
brew doctor
The above command will list the broken system links. In order to get rid of these broken symlinks, put this:
brew prune
Check with ‘brew doctor’ once more to ensure no links are broken. Your system will then be ready to brew.
You can use this solution as I’ve put below
sudo rm -rf /Library/Frameworks/Python.framework
brew doctor
brew prune
brew update
That combo fixed it for me, even thought this error usually doesn’t cause any major problems its just was annoying me to see them pop up under brew doctor
I had installed Python 3 from Homebrew and then another Python 3 directly from the Python website.
I deleted /Library/Frameworks/Python.framework. I did not add any PATH or PYTHONPATH variables in .bash_profile. Then I checked the following in the shell:
~$ python
Python 2.7.10 (default, Feb 7 2017, 00:08:15)
[GCC 4.2.1 Compatible Apple LLVM 8.0.0 (clang-800.0.34)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> quit()
~$ python3
Python 3.6.4 (default, Mar 9 2018, 23:15:12)
[GCC 4.2.1 Compatible Apple LLVM 9.0.0 (clang-900.0.39.2)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> quit()
~$
In addition, I checked the following:
~$ whereis python
/usr/bin/python
~$ whereis python3
~$ which python
/usr/bin/python
~$ which python3
/usr/local/bin/python3
~$ which pip
/usr/local/bin/pip
~$ which pip3
/usr/local/bin/pip3
~$ whereis pip
~$ whereis pip3
I was a bit worried that whereis python3, whereis pip, and whereis pip3 returned nothing, but since there was no problem launching Python, I’d think it’s safe to delete /Library/Frameworks/Python.framework. Ask me again in a month.
