It seems that the python3.7 update has caused this issue.

I'm using vim and fixed with this command:
brew reinstall vim --with-python@2

If you are using macvim, maybe you can try this command:
brew reinstall macvim --with-override-system-vim --with-python@2

This will happen when running any python3 (while using python3.7) in vim. not specific to Ultisnips.

See https://github.com/vim/vim/issues/3117

To anybody else who's having this issue, I think this is the best workaround:

Regardless of installed plugins, silently execute python3 once on the top of your vimrc:

if has('python3')
  silent! python3 1
endif

The issue has been fixed in Vim with the patch 8.1.0201.
