Vim Vundle PluginInstall fails because of "command not found"

Question

When I run :PluginInstall on Vim, I get the following log output:

[2020-07-21 13:50:38] Plugin URI change detected for Plugin Vundle.vim

I've tried the following:

1. Run rm -rf .vim and rm .vimrc and rm .viminfo;
2. Run brew uninstall macvim;
3. Make sure my .zshrc contains export PATH=$HOME/bin:/usr/local/bin:$PATH and export PATH="/usr/local/sbin:$PATH";
4. Copy and paste the .vimrc from the Vundle README;
5. Open vim and run :PluginInstall

Yesterday, I installed the following:

• Plugin 'airblade/vim-gitgutter'
• Plugin 'dense-analysis/ale'
• Plugin 'preservim/nerdtree'
• Plugin 'Xuyuanp/nerdtree-git-plugin'
• Plugin 'sheerun/vim-polyglot'
• Plugin 'tpope/vim-fugitive'
• Plugin 'wakatime/vim-wakatime'
• Plugin 'ycm-core/YouCompleteMe'

I installed them all according to the methods in their respective GitHub READMEs; not necessarily Vundle. Everything was working fine yesterday. I tried uninstalling Ale today and all Hell broke loose.

BTW, I did not have export PATH=$HOME/bin:/usr/local/bin:$PATH or export PATH="/usr/local/sbin:$PATH" in .zshrc yesterday. I added sbin first-thing today as a result of a brew doctor warning. I uncommented the bin line just for kicks. Neither had any effect on Vim.
