Mac Manually install VIM with supporting Python3

I include this answer to "Way 0" and "Way 1" and "Way 2".

Way 0

1.run the below on terminal

brew reinstall python3

the upstairs shows that we reinstall python3 to make sure that needed by VIM.

2.continue run on terminal

brew uninstall vim

the upstairs shows that uninstall vim only if you previously installed it

3.run on terminal

brew install vim

the upstairs shows that reinstall vim via Homebrew.

4.run on terminal

4.1 directly use $SHELL command

alias vim=/usr/local/bin/vim

4.2 or bash 's profile(if you use bash as SHELL)

echo 'export PATH="/usr/local/opt/vim/bin:$PATH"' >> ~/.bash_profile

source ~/.bash_profile

4.3 OR zsh configuration file(if you use zsh as SHELL)

edit your zsh configuration file ~/.zshrc via

vim ~/.zshrc

and add the below to TOP line(just use i to enter editing status,

then use ":wq" to quit editing status and save file):

export VIM_HOME=/usr/local/Cellar/vim/8.2.2100/

export PATH=$PATH:$VIM_HOME/bin

and active that config

source ~/.zshrc

(Both 4.1 or 4.2 or 4.3 are the same function.)

the upstairs 4.1/4.2/4.3 shows that we let shell command vim using HomebrewVIM not the defaultVIM.

We know the default VIM functional file is located at /usr/bin/vim,

while homebrew VIM functional file is located at /usr/local/bin/vim;

And default VIM support Python2 with not supporting Python3,

but homebrew VIM support Python3(That's also we needed!).

Let's look at Homebrew VIM:

Homebrew will install VIM vim at /usr/local/Cellar/vim,

create soft link vim under /usr/local/opt,

and Homebrew VIM 's functional file vim is located at /usr/local/bin/vim, also linked to /usr/local/Cellar/vim.

Way 1

First

you need to use this to checkout whether VIM support Python3 or not?

vim --version | grep python

you may see the terminal output liking:

+conceal           +linebreak         -python3           +visual

as the upstairs shows: that Mac default installed VIM DO NOT SUPPORT Python3.

And that default installed VIM of Mac is not been installed via "brew".

Now, we could not use liking "brew remove" to delate that default installed VIM of Mac,

and it's also why your action

"brew delete vim and brew cleanup and reinstalled Vim"

DO NOT FUNCTION!

Second

we need to know where that fu-king default installed VIM with not supporting python3,

which vim

output:

/usr/bin/vim

mostly shows like the upstairs(depends default macOS).

Even we use "--with-python3" to install VIM with supporting

Python3at a long time, but Now Homebrew ONLY recognize "python -V"'s version.

SO we NEED to manually let default python to be python3.

Open your terminal and input:

alias python="python3"

then checkout python that that version whether is python3 or not:

python -V

then, we found that "python -V" shows "Python 3.9.12".

Third

That's time to use Homebrew to install VIM.

brew install vim

After installing HomebrewVIM, we need to make sure where is HomebrewVIM,

differ from that default installed VIM of Mac:

which vim

output:

/usr/local/bin/vim

Please restart Your Mac, restart Your Terminal and reenter your terminal!!!

Please restart Your Mac, restart Your Terminal and reenter your terminal!!!

Please restart Your Mac, restart Your Terminal and reenter your terminal!!!

then, we need to checkout whether that HomebrewVIM supports Python3 or Not:

vim --version | grep python

output:

+conceal           +linebreak         +python3           +visual

Successful!
