How do you install plugins for MacVim?

Question

Specifically, I'm trying to install NERDtree. I downloaded the 4.10 package from github, unzipped it into ~/.vim/, and restarted MacVim (version 7.3).

Typing :nerdtree results in the following error:

E492: Not an editor command: nerdtree

In terminal, typing:

cd ~/.vim
ls -R

Results in:

Rakefile    doc     nerdtree_plugin plugin

./doc:
NERD_tree.txt

./nerdtree_plugin:
exec_menuitem.vim   fs_menu.vim

./plugin:
NERD_tree.vim

What am I missing?

Solution

The command is :NERDTree—case does matter, especially since only internal Vim commands can start with a lowercase letter.

If you followed the installation instructions you should be able to do ":help NERD_Tree.txt". If not, do ":helptags ~/.vim/doc".

This was it. Thank you! I had also tried NERDtree, but I never tried it with a capital T. :\
