Answer 1

It is an old question but I wanted to add I simply installed macvim and re-started terminal again. It solved my problem

- brew install macvim

I use terminal vim, but installing this somehow fixed my terminal vim as well ! Thanks :) – Lanyard

Same here. Thank you very much. – Krasnoff

Answer 2

I'm aware that this isn't directed at your question per say, but I ran into the same issue on Ubuntu with nvim. Reinstalling didn't help, but adding https://github.com/neovim/pynvim fixed my issue. Perhaps it can be helpful to Mac users using nvim too.

you can use vim --version | grep python to check your vim. If vim detects the python3, it will show like:

+cmdline_hist      +langmap           -python            +viminfo
+cmdline_info      +libcall           +python3           +virtualedit

The python3 will have a + sign in front of that.

If not, first, you must check if you have python3.

Second, you need to uninstall vim (sudo apt purge vim), then reinstall vim (sudo apt install vim).

Third. Reconfirmation by vim --version | grep python.

I hope this can help you.

I have python3 install and proceeded with the uninstall and reinstall as you suggest but I still have a - instead of + in front of python3 – Vanessa

In the end, following these steps as well as installing python3-dev was able to get the +python in my versioning. In my opinion this is the cleanest solution that required the fewest modifications or installs that didn't make sense +1 – Vanessa

Answer 4

Yes, you can reinstall the latest vim version with homebrew: https://formulae.brew.sh/formula/vim

But, I think you should recheck your vim version with :version, there is no version like yours.

And the latest version itself depends on python, and more like nvim.

# I do like this
brew install vim --HEAD

Answer 5

Confirmed

brew install macvim

worked for me after restarting terminal. Make sure to

brew uninstall vim

before installing macvim, then restart terminal. Solved it for me on new Mac with new apple chip.

Answer 6

Thankfully, the error message is pretty solid. You need vim with Python, Now while I don't personally have a mac that should be as straightforward as making sure you install the correct version.

The simplest way is probably going to be with brew as mentioned here.

brew remove vim
brew cleanup
brew install vim --with-python

If you installed it with a binary you will need to find a new binary with python included. Or alternatively you could try and build it from source as the comment from Zoe suggested. But I think that may be somewhat more involved than ideal for a beginner, although worthwhile.

It doesn't seem, like this actually involves neovim at all, If it does then you may want to update your question, otherwise it is a good idea to remove the neovim tag.
