Why does this happen? I get the below output when running which rbenv in terminal:

rbenv () {
    typeset command
    command="$1" 
    if [ "$#" -gt 0 ]
    then
        shift
    fi
    case "$command" in
        (rehash|shell) eval `rbenv "sh-$command" "$@"` ;;
        (*) command rbenv "$command" "$@" ;;
    esac
}

Was supposed to use which rbenv to detect rbenv for this plugin - maltize/sublime-text-2-ruby-tests#154. Any help would be appreciated. :)

This is a difference between the binary (/usr/bin/which) and Zsh's built-in command of the same name.

Like @graywh said: which can be either a shell builtin or a command in your PATH. To see which you are using: type which

What you are seeing as a result for which rbenv is correct. If you want to detect the path to the rbenv executable, you can use command which rbenv.

➜ ~ type which
which is a shell builtin
➜ ~ command which rbenv
/usr/local/bin/rbenv
➜ ~ echo $PATH
/usr/local/opt/rbenv/shims:/usr/local/sbin:/Users/Young/.rbenv/shims:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin

I think the path to the rbenv executable should be ~/.rbenv/bin/rbenv, what's my problem?

I once did the follow stuff:

curl -O https://raw.githubusercontent.com/donnemartin/dev-setup/master/.bash_profile
curl -O https://raw.githubusercontent.com/donnemartin/dev-setup/master/.bash_prompt
curl -O https://raw.githubusercontent.com/donnemartin/dev-setup/master/.aliases

source .bash_profile, and then bugs came out. I delete them all. does this cause it ?

@sundevilyang You seem to have eventually successfully set up rbenv, as evident by Ruby version being 2.3.1 when you did rbenv -v, but the gem installation error I can't help you with, since that's not rbenv's responsibility. You'll have to search the web for the answers for that one.
