Installing Vim with Python3 support? - python-3.x

Question

I installed Vim on my MacBook today (using brew install vim), but I am having a problem: vim --version tells me that there is no Python 3, which I need. I already reinstalled the newest version of Python from their website, then did brew delete vim and brew cleanup and reinstalled Vim, but I'm still having the same problem. Online, I saw the option to use the flag --with-python3 when installing, but when I try that, I get told that this flag doesn't exist. Now I don't know what to do. Do I need to install Python via Homebrew? I also found some people online saying that there are versions of Vim compiled without Python, and that you can compile Vim yourself. Do I need to do that? How?
I should add: I'm very new to this, so if you post your answers or maybe need some more information from me, please explain in detail so I can understand.

Answer 1

I'm a new too.
First, use brew to remove vim you should input brew uninstall vim.Then try to reinstall vim.
For instance, if you wanted to recompile Vim 8 with Python 3 support on Linux, you can try do the following:
$ git clone https://github.com/vim/vim.git
$ cd vim/src
$ ./configure --with-features=huge --enable-python3interp
$ make
$ sudo make install

Answer 2

So,
I include this answer to "Way 0" and "Way 1".
_______________________________________________________________---Way 0 Begin---(:
Way 0:
we should reinstall python3 and VIM,
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.
5.exit terminal and restart terminal or even restart mac, input
the below on terminal
vim --version | grep "python3"
checkout whether the symbol bdfore "python3" is + or Not?
"+" means VIM support python3, but "-" Not.
____________________________________________________________---Way 0 END---:)
____________________________________________________---Way 1 Start---(::
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!
