执行type rvm | head -1出现 rvm is a shell function 我的环境应该有些问题，
求帮助。
神呢 楼主看看他说的这句话的意思呗 如果你的 ~/.profile 文件里有你自己添加的东西的话 需要你自己把他加到 zsh 的 profile 里 就是这样...
这句的意思难道不是说跑一下 source ~/.profile 么？ 当然 ZSH 下可能是 source ~/.zprofile 或者 source ~/.zshrc
#3 楼 @kvoid 是啊。 If you open a new shell and running:
type rvm | head -1
does not show "rvm is a function", RVM isn't being sourced correctly.

你的环境真的没有什么问题，那个就是一个善意的提醒罢了。这段 Waring 出自 https://github.com/wayneeseguin/rvm/blob/2e36865f4140d5877a62bf7918b8b7a8504aeaa1/scripts/notes#L185-L206
有的系统默认有一个 .profile，然后 rvm 生成了 .bash_profile，然后有的 login shell 在有 .bash_profile 的情况下就不会读取 .profile 了，所以提醒你要在 .bash_profile 里面 source .profile，但是如果你在 .profile 里面没有什么内容就不用管了。
#13 楼 @RainFlying 我把 .bash_profile 删除，在 .profile 里面加一句 echo '.profile' ，然后开新的终端，有显示出 .profile。然后把 .bash_profile 恢复，开新的终端，就不显示 .profile 了。
#15 楼 @RainFlying .bashrc 里面没写有读 .profile 的规则。Ubuntu 的 man bash 写有：
When bash is invoked as an interactive login shell, or as a non-interactive shell with the --login option, it first reads and executes commands from the file /etc/profile, if that file exists. After reading that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable.
