which is the default vim version installed on my mac. Unfortunately, it says: -python3. So I assume python 3 is not installed. So what I did is the following:

brew remove vim which went ok and then brew info vim and got the following message:

Vi 'workalike' with many additional features

Conflicts with:
  ex-vi (because vim and ex-vi both install bin/ex and bin/view)
  macvim (because vim and macvim both install vi* binaries)

Is it because there are 2 versions of vim installed now?

I also tried brew install vim --with-python3 but got the following message invalid option: --with-python3 when typing vim --version, I get:

vim --version

EDIT

Here are commands with their corresponding outputs

• sudo nano /etc/paths:

/usr/local/bin
/usr/bin
/bin
/usr/sbin
/sbin

• command -v vim:

/usr/bin/vim

• $PATH:

-bash: /Library/Frameworks/Python.framework/Versions/3.7/bin:/usr/local/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/TeX/texbin:/opt/X11/bin: No such file or directory

Moreover I posted a similar question on another platform and did many attempt to try solving the problem. However the problem still persists.

Answer 1

Try

./configure \
--with-python3-command=python3

Both --with-python3 and --with-python3-config-dir are deprecated.

Answer 2

The version of Vim you're running is the built-in Apple version, which you can see in the second line ("Compiled by root@apple.com"). You can install either the vim or macvim packages with Homebrew and they will have Python 3 built in, since, as ParthS007 mentioned, the default Python is Python 3.

However, your PATH environment variable will need to have /usr/local/bin before /usr/bin if you want to use the Homebrew version over the default system version (which you almost certainly do). You can edit your shell configuration to change the setting and then restart your terminal session.

If your PATH environment variable is set correctly, it's possible you may also have to run brew link vim (or brew link macvim) to create the appropriate symlinks. In general, you'll want command -v vim to show /usr/local/bin/vim. Running /usr/local/bin/vim by hand should show the correct Vim installed.
