I want to use Ultisnips and get the following error:

```
E319: Sorry, the command is not available in this version: py3 import vim
Press ENTER or type command to continue
Error detected while processing /Users/Me/.vim/plugged/ultisnips/autoload/UltiSnips.vim:
line    8:
E319: Sorry, the command is not available in this version: py3 from UltiSnips import UltiSnips_Manager

```

I think this correlates to the fact that I get `0` as the output when running `:echo has('python3')`. How can I fix this issue?

My operations system is macOS Big Sur.

I have tried several times to reinstall vim with home-brew but I still get [![enter image description here](https://i.stack.imgur.com/Hc1h2.png)](https://i.stack.imgur.com/Hc1h2.png)

when executing `vim --version`. Any idea how one can fix this on MacOS?
