ruby - Gem 安装不会创建指向 bin 的链接

Question

我正在尝试在 Mac 上安装 cocoapods

Successfully installed cocoapods-0.25.0
1 gem installed

但是

$ pod install
-bash: pod: command not found

Ruby 是使用 brew 安装的

$ which ruby
/usr/local/bin/ruby

$ which gem
/usr/local/bin/gem

这是 gem 环境的输出

$ gem environment

我应该将什么导出或添加到 .bash_profile 以使 pod install 正常工作？

如果您使用 rbenv像我一样，在安装 gem 后，您必须运行 rbenv rehash 才能在 shims 目录中获取链接。
