在Macvim中打开/安装ctags（已安装自制软件，oh-my-zsh，janus）

Question

I installed macvim using homebrew on my Mackbook Pro (lion). once that was installed I installed janus. I also installed oh-my-zsh (if that helps solve this problem). I can't seem to get ctags working though. In MacVim when I do Tools>Build Tags File I get:

:!ctags -R .
ctags: illegal option -- R
usage: ctags [-BFadtuwvx] [-f tagsfile] file ...

shell returned 1 
Press RETURN or type command to continue

How do I get it to work?

Here's some additional info that may help you:

Answer 1

It definitely looks like Vim is picking up /usr/bin/ctags, which doesn't recognize -R , instead of /usr/local/bin/ctags. This can happen if put /usr/local/bin in your path only for login shells.

You might want to make sure /usr/local/bin gets added to your path in the non-login, non-interactive environment file. I don't use zsh myself, but it looks like that would be .zshenv.

On a mac, by default the path that vim uses and the path that the terminal (bash/zsh) uses are different, so even if you have the correct path set in the terminal, it won't translate to vim correctly, to rectify this situation, you need to run

sudo chmod ugo-x /usr/libexec/path_helper
