Problems installing Nerdtree

Question

According to the nerdtree install directions, I needed to install pathogen.vim to install nerdtree. To install pathogen.vim, I followed the pathogen install instructions, and I did this:

~$ mkdir -p ~/.vim/autoload ~/.vim/bundle; \
> curl -so ~/.vim/autoload/pathogen.vim \
> <link to github>

That created pathogen.vim here:

~/.vim/autoload$ ls

pathogen.vim  … … …

Then I followed the pathogen install instruction:

Add this to your vimrc:

call pathogen#infect()

==

~$ cat .vimrc
…
…
"For pathogen(a vim installer):
call pathogen#infect()

Then following the nerdtree install instructions:

pathogen.vim is the recommended way to install nerdtree.

cd ~/.vim/bundle
git clone <link to github>

Then reload vim, run :helptags, and check out :help NERD_tree.txt. 

I tried to install nerdtree like this:

~/.vim/bundle$ git clone <link to github>

Which produced:

~/.vim$ cd bundle
~/.vim/bundle$ ls
nerdtree

But I can't get nerdtree to work. When I try this:

~$ cd rails_projects/demo_app22/
~/rails_projects/demo_app22$ mvim .
~/rails_projects/demo_app22$ 

...and then this:

:NERDtree

I get the error:

E492: Not an editor command: NERDtree

And when I try :helptags, I get the error:

E472: Argument required
