Can't Access Vim's Builtin Help: E149

When I type :help, I get the following

E433: No tags file
E149: Sorry, no help for help.txt

I installed vim via homebrew

$ which vim
$ /usr/local/bin/vim

How did you install vim?

$ brew install vim

I uninstalled vim and the problem was resolved,
then I installed macvim

$ brew install macvim --with-override-system-vim
