For some reason macvim installed with brew doesn't have the python3 support. Here is how I installed it:
brew install macvim --with-cscope --with-python3
Whenever I run
:echo has('python3')
The result is 0, meaning there is no python3 support. Does anybody know what is the problem? Any help is appreciated.
Python 3 is deliberately disabled in the macvim recipe in homebrew.
You can, however, run "brew edit macvim" and fix up the recipe so it works.
I recommend the following actions (which have worked for me):
Use the current MacVim 7.4 snapshot 72 (update the url and sha1). brew still has older snapshot 71.
sha1 '3fb5b09d7496c8031a40e7a73374424ef6c81166'
Delete all the patches from the end of the recipe. The last line should be __END__. None of the patches are necessary anymore - ruby support was fixed upstream in snapshot 72.
depends_on :python3 => :recommended
in the install function, when its messing with the args, fixup the python section like so:
args << "--enable-python3interp=yes" if build.with? 'python3'
ENV.prepend 'LDFLAGS', "-L#{python3.libdir} -F#{python3.framework} -framework Ruby" if python3 && python3.brewed?
Ensure you use a homebrew python3 and if you have upgraded to Mavericks, re-brew absolutely everything - the stdc++ library has changed and you cannot mix old and new when linking.
brew it with:
$ brew install --HEAD macvim
$ mvim --version # to ensure it has all the right things linked
I've run through ultisnips and vinarise, both of which work and neither of which caused the window to mysteriously disappear as previously lamented in the recipe for macvim & python3. I've also done other basic testing with :py3 command. No issues seen (yet)

python3 env is not used when I update my Mac to the latest version. How can I solve it?
This worked for me with the same issue.
Check if you have multiple Python3.x versions installed. In my case I had Python3.6 and Python3.9 installed. brew uninstall python3 did not remove Python3.6 completely.
I was able to call Python3.9 from Terminal by explicitly running python3.9 instead of python3, which led me to believe the issue was caused by ambiguity in which Python3.x resource was to be used.
Manually deleted /Library/Frameworks/Python.framework/Versions/3.6 resulted in Python3 running as expected.
hint:
It may be sufficient to remove /Library/Frameworks/Python.framework/Versions/3.6 from your PATH environment variable.
Check in the location:
/usr/bin/python3
If you can invoke python3 interpreter from this location without any issues, copy this to
/usr/local/bin/python3
I upgraded to macOS Big Sur and had faced the same issue. I was not able to open Python interpreter from terminal and the Python version inside Library/Frameworks/Python.framework/Versions/3.6 was also being pointed to Python2.7.
Later, I found python3 in location /usr/bin/python3 working fine for me. I also tried creating a symlink for python3 to the above path but didn't work.
That's becuase you have installed both python 3.6 from system library & python3.9 from other source like brew and there are something wrong with the python in lower version. Please manually delete the python within /Library/Frameworks. sudo rm -rf /Library/Frameworks/Python.framework/Versions/3.6 this command works for me.
I encountered this same problem on Step 1 of PyCharm's Create a Django project documentation.
I had previously set up Python on my Mac following these instructions. Can't promise this solution will work for everyone, but maybe if someone's Python was set up similar to mine the following solution that worked for me might help you...
Open Terminal
which python3
Copy the directory given to you... (For me it was /Users/foo/.pyenv/bar/python3)
When creating your new Django project in PyCharm (Professional Edition), set your base directory to the one received from which python3
Create your project
My case
Deleted Xcode (Maybe some folders are accidentally deleted like /Library/Frameworks/...
Also installed Python with anaconda.
My solution
Reinstall Xcode
Followed this to remove anaconda then everything works fine
On my Mac terminal i've installed python3 (3.7.6) using homebrew - e.g. if I issue command to upgrade via homebrew, it returns the up to date version:
$brew upgrade python3
Warning: python3 3.7.6_1 already installed
However when I ask for the version it tells me an older version (3.4.0) is installed:
$python3 --version
Python 3.4.0
So it's installed but not updated. I'd quite like 3.6 or later on my mac. I've tried uninstalling and reinstalling using homebrew, and had no luck. Wondering if anyone has any ideas?
//
Sidenote (1) - i'm relatively new to homebrew... $ brew doctor returns config scripts "outside your system or Homebrew directories" - not sure if this helps, and if this is the issue where to move them to.
/Library/Frameworks/Python.framework/Versions/3.4/bin/python3.4m-config
/Library/Frameworks/Python.framework/Versions/3.4/bin/python3-config
/Library/Frameworks/Python.framework/Versions/3.4/bin/python3.4-config
Sidenote (2) - 3.7.6 isn't the newest version out, but this is the latest version that homebrew will install. Is there any way to get an even newer version?
By chance i've come across the/a answer. I was editing .bash_profile and saw the very top says:
# Setting PATH for Python 3.4
# The orginal version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/3.4/bin:${PATH}"
export PATH
So I moved to this directory .../Versions/, found it had three subdirectories 3.3, 3.4, and 3.8, and updated to use:
PATH="/Library/Frameworks/Python.framework/Versions/3.8/bin:${PATH}"
And this seems to do the trick (to use the most recent). Although interestingly i've not came across 3.7.6... but is a bit redundant in my case since I can use the newer 3.8 version.
Quick fix:
You should be able to run the required version by running python3.7 instead of python3. You can set up an alias if you like with
"alias python=/usr/local/bin/python3.7"
where you put the desired binary on the RHS. This will create an alias for your current session. To always evoke this functionality, you can add this line to your bashrc file so this alias will work every time you log in to a new session
echo "alias python=/usr/local/bin/python3.7" >> ~/.bashrc
These commands were lifted from
https://opensource.com/article/19/5/python-3-default-mac
which explains some do and do-nots.
Alternative:
Also check out Python virtual environments, particularly virtualenv and virtualenvwrapper, which are great tools for separating out your Python working environments and allow you to set default Python version for each project separately, as well as managing any modules you pip install separately for each project. This is much cleaner in my opinion.

I'm trying to use Anaconda python3.7 + vim 8.1 + jedi-vim on Rocks 7.0 (Manzanita) but I get an error saying that libpython3.7m.a cannot be loaded and I can't find a solution.
First things first. I have to compile vim by myself because the vim installed by default has only +python and I have to use python3.
I cloned the git and, following several other suggestions found online I configure vim with
./configure --enable-cscope --enable-multibyte --enable-python3interp=dynamic --with-features=huge --with-python-config-dir=/home/mazzi/miniconda3/lib/python3.7/config-3.7m-x86_64-linux-gnu --with-tlib=ncurses --enable-fail-if-missing --prefix=/home/mazzi/.local
The prefix is due to the fact that I don't have root access and its output of can be found here. Please note that during the whole procedure I had to stay inside a conda environment, otherwise the configuration would fail saying that no python3 was found.
I then make, with this output, and make install with this other output.
I check vim version and everything seems ok.
Finally, I start vim normally (/home/mazzi/.local/bin is on the PATH, before the system paths, and the vim command points to ~/.local/bin/vim) and type :py3 pass but I get the following error:
E370: Could not load library libpython3.7m.a
E263: Sorry, this command is disabled, the Python library could not be loaded.
What can I do?

I have 4 versions of macvim installed in homebrew's Cellar folder. I want the most recent version only to be my default vim everywhere, ie, when I type gvim or vim from the command line.
brew linkapps macvim does not work, ie, gvim still gives "No such file" after running it.

==> Caveats
.app bundles were installed.
Run `brew linkapps macvim` to symlink these to /Applications.
UPDATE
When I run brew doctor, the relevant message is:
Warning: You have unlinked kegs in your Cellar
Leaving kegs unlinked can lead to build-trouble and cause brews that depend on
those kegs to fail to run properly once built. Run `brew link` on these:
macvim
vim
However, when I brew link macvim, it links back up the previous version of macvim, rather than the most recent one.
Please run brew prune to remove broken links. Also brew doctor can help you finding additional problems.

According to this blog post, you just have to compile the YouCompleteMe modules by running the install.sh script in the YCM install.
cd ~/.vim/bundle/YouCompleteMe
./install.sh --clang-completer
Once this completes you should be able to install the plugin (here's how to do it with Vundle). Once in Vim
:source ~/.vimrc
:PluginInstall
Apparently, when you run ./.install.sh --clang-completer it says that it is "out of date."
I ran python2 install.py and it worked for me. (I believe it was python2.)
Also, I had was using vim and neovim, and I decided to do ./install.sh --clang-completer inside my ~/.vim/bundle/Vundle.vim/ and at the same tim decided to do python2 install.py inside my ~/.configs/nvim/bundle/Vundle.vim/ and the python install installed faster and did the same thing.
The difference might be that you need to "compile vim with pdython support," but the simple fix for that is installing python-nvim (if using neovim), or - I think - vim just comes with python support. (? maybe.)
I encountered the same error message when trying out new neovim installation. In my case, it was because I was using vim-plugin and the plugins are installed in the ~/.vim/plugged instead of ~/.vim/bundle (this is the plugin folder for Vundle before I switched to vim-plug).
Thus, after scratching my head for few hours, turns out I have to run install.sh in the ~/.vim/plugged (not ~/.vim/bundle). I hope this will save someone's time.
