In the google searches I've done, the command I should be using is brew install vim --with-python3, which succeeds without error, but then vim --version reports Python 3 as unavailable.

k162:~ asday$ brew install vim --with-python3

And doing :py3 print("") within vim returns E319: Sorry, the command is not available in this version.

What is it I'm doing wrong? Do I need to compile vim myself?

The following works as of 26 May 2017 when a -python3 version of Vim is already installed via homebrew:

brew remove vim

brew cleanup

brew install vim --with-python3

I got the same issue today. No matter

brew install vim --with-python3

or

brew install vim --without-python --with-python3

So i check Homebrew's logs at ~/Library/Logs/Homebrew/vim, in 01.configure i found

checking Python is 3.0 or better... too old

This is because configure can not find python3's path

By adding /usr/local/Cellar/python3/3.X.X/bin (your path may be different) to your PATH envoriment and re-run, the vim finally got compiled with +python3

Already get to make it work. vim formula installs vim with python3
support only if python --version is version 3. Doesn't matter if brew
install python install python version 3 (because it does in another
binary: python3)

From: https://www.reddit.com/r/vim/comments/8iymh8/vim_in_osx_with_python3_support/dyx1b94/

Here are my steps:

1. alias python=python3


2. brew install vim


3. at this point, I get +python3 in the vim --version output


4. unalias python

Since version 1.6.0 of Homebrew (2018-04-09), the default python version is 3. Thus, if you have a version of vim installed before this change which is compiled with python2, what you need to do now to get vim with python3 is simply:

$ vim --version | grep python

$ brew uninstall --force vim

$ brew cleanup

$ brew install vim

$ vim --version | grep python

It is because there was an already installed vim in your system which is normally found in /usr/loca/vim

$ which vim

You can try ls /usr/local/Cellar/vim/7.4.2210 and take a look what folders are available. In my system, in that directory i have bin/vim, so I update my .zshrc or similar rc file in your os, update it as

alias 'vim'=/usr/local/Cellar/vim/7.4.2210/bin/vim

When you open a new terminal, then

which vim

It will show the update path. So you can use the python3 inside it.

As of October 2017 this works.

If you have previously installed vim with homebrew, uninstall it first

brew remove vim

brew cleanup

Then

brew install vim --without-python --with-python3
