为什么我需要将 ~/.rbenv/bin 添加到我的路径中？

Question

我在“rbenv can't change global ruby version”中读到我需要将 ~/.rbenv/bin 添加到我的 PATH 以使 rbenv 工作。

documentation中也提到了，但该目录不存在，如下所示：

➜  ~ ls -a ~/.rbenv/
.  ..  plugins  shims  version  versions

那么，为什么我需要添加一个不存在于我的路径中的目录才能使 rbenv 正常工作？

编辑：

@theTinMan，我已经尝试卸载并重新安装，但我仍然没有 ~/.rbenv/bin 路径。您在文档中的什么地方看到它应该在那里？

➜  ~/D/w/t/underline-test  rbenv --version
rbenv 1.0.0
➜  ~/D/w/t/underline-test  which rbenv
rbenv () {
    local command
    command=""
    if [ "$#" -gt 0 ]
    then
        shift
    fi
    case "$command" in
        (rehash | shell) eval "$(rbenv "sh-$command" "$@")" ;;
        (*) command rbenv "$command" "$@" ;;
    esac
}
➜  ~/D/w/t/underline-test  cd
➜  ~  ls .rbenv
plugins  shims    version  versions
➜  ~  brew list | grep rbenv
rbenv
➜  ~
➜  ~  brew uninstall rbenv
Uninstalling /usr/local/Cellar/rbenv/1.0.0... (36 files, 61.9K)
rbenv 0.4.0 is still installed.
Remove all versions with `brew uninstall --force rbenv`.

我的 .zshrc

中有以下内容

export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"

但我只需要底线

# export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)"

为什么我需要将 ~/.rbenv/bin 添加到我的路径中？

Why do I need to add ~/.rbenv/bin to my path?

ruby

bash

path
