Question

I use plain Vim with ruby support on Lion (installed by gist). I am using ruby with rbenv so my path looks like /users/me/.rbenv/shims:.....

From within vim the pat

Answer 1

This can be fixed by just adding

PATH=/home/me/.rbenv/shims:${PATH}

to

/etc/zshenv

Answer 2

This is a known problem introduced by Apple in OS X 10.5 Leopard.

If you are using Bash or Zsh and are using non-interactive shells, you are affected.

Running sudo chmod ugo-x /usr/libexec/path_helper will fix you up, but you should take a look at the article to see why.

Answer 3

rvm also has this problem. If zsh is your default shell when it starts /etc/zshenv gets executed.

This executes /usr/libexec/path_helper. That sets up the path based on the contents /etc/paths and /etc/paths.d/.

The faq for rvm mentions moving /etc/zshenv to /zsh/zshrc. I did this and it removed the /usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin from the start of my path in macvim.

Answer 4

yes on OS X it's the bash_profile that gets sourced when opening a new console window whereas on Linux it's your bashrc

Answer 5

In your ~/.bashrc (or whatever shell you're using) file, add the following line:

PATH=/home/me/.rbenv/shims:${PATH}

and then run source ~/.bashrc (or .zshrc or whatever shell you're using!)

Answer 6

I did'n t set the shell option in .vimrc, so that it was automatically set to /bin/zsh.

Then I found out that I hab a dublicate initialisation of rbenv: in my .zshrc. I removed the initialisation end $PATH extensioin in .zshrc because that was already handled by the oh-my-zsh rbenv plugin.

Even after that cleanup, the $PATH mangeling still happening so :!echo $PATH

/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/Users/fb/.rbenv/shims:/Users/fb/.rbenv/bin:/Users/fb/bin:/usr/local/sbin:/usr/games

Setting :set shell=/bin/bash was what helped me, as i can live with bash in my vim: :!echo $PATH

/Users/fb/.rbenv/shims:/Users/fb/.rbenv/bin:/Users/fb/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/Users/fb/Dropbox/local/bash
