I tried to open the help file for NERDtree in vim. However when I typed :helptags I got the error E471: Arugment required

After that I typed :help NERD_tree.txt but I got the error E149: Sorry, can't find help for NERD_tree.txt

Help instructions are taken from: http://www.vim.org/scripts/script.php?script_id=1658

I know that I can just open NERD_tree.txt in any editor manually (for example vim or Emacs), but I'm just asking out of curiosity.

PS I'm a vim noob. :P

You have to give :helptags the directory where the help file (that you want to be parsed) is. For example:

:helptags ~/.vim/doc

I had the same problem, and resolved it with tips from another SO thread:

Apparently you need to :Helptags rather than :helptags

I had the same problem, and specifying the directory for :helptags didn't resolve the problem. It didn't return an error, but it also didn't make :help NERD_tree.txt work. The solution that worked for me was installing pathogen.vim, which is recommended in the NERD Tree installation directions. After I did that, :help NERD_tree.txt worked.

This is an old thread which I stumbeld upon. I will post my workaround anyways. maybe it can be usefull for another one searching like I did.

I opened a terminal in .vim/pack/bundle/start/nerdtree/doc and then started vim.

:helptags .

did the trick for me.
