问题说明

我正在为 Apple Silicon - Mac M1 运行 OS X，使用 .zshrc shell（不是 bash），并尝试按照以下说明安装 RVM 以贡献于开源项目：

使用 Homebrew 安装 gpg 以验证 RVM 安装程序的完整性。 brew install gpg brew doctor 并得到了Your system is ready to brew.，看来我添加成功了。
下载 RVM 安装程序的公钥。 gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB 而且我没有收到任何错误，似乎也成功了。
要安装 RVM 和最新版本的 ruby 和 rails，这可能是个好主意，请使用以下命令。 \curl -sSL https://get.rvm.io | bash -s stable --autolibs=enable 这将返回以下内容并带有 *Warning at the end：

作为验证一切顺利的最后一步。 type rvm | head -1 这将返回rvm is a function。但是，我收到rvm is a shell function from /Users/sarvarkhalimov/.rvm/scripts/cli

我的脚本（源）文件

1. ~/.bash_profile

source ~/.profile
export PATH=/opt/homebrew/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin

export PATH=/opt/homebrew/bin:/opt/homebrew/bin:/Users/sarvarkhalimov/.rbenv/shims:/opt/homebrew/bin:/opt/homebrew/sbin:/Users/sarvarkhalimov/.rvm/gems/ruby-2.7.3/bin:/Users/sarvarkhalimov/.rvm/gems/ruby-2.7.3@global/bin:/Users/sarvarkhalimov/.rvm/rubies/ruby-2.7.3/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/sarvarkhalimov/.rvm/bin:/Users/sarvarkhalimov/.rvm/bin
export PATH=/opt/homebrew/bin:/opt/homebrew/bin:/opt/homebrew/bin:/Users/sarvarkhalimov/.rbenv/shims:/opt/homebrew/bin:/opt/homebrew/sbin:/Users/sarvarkhalimov/.rvm/gems/ruby-2.7.3/bin:/Users/sarvarkhalimov/.rvm/gems/ruby-2.7.3@global/bin:/Users/sarvarkhalimov/.rvm/rubies/ruby-2.7.3/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/sarvarkhalimov/.rvm/bin:/Users/sarvarkhalimov/.rvm/bin

export PATH="/usr/local/bin:$PATH"

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*

2. ~/.bashrc

export PATH="$PATH:$HOME/.rvm/bin"

3. ~/.zshrc

eval "$(rbenv init -)"

export PATH="/opt/homebrew/bin:$PATH"
export PATH="/usr/local/bin:$PATH"

export PATH="$PATH:$HOME/.rvm/bin"

采取措施解决：

我在 2012 年遇到了 @elado 的以下 solution，我尝试将我的第一个导出路径 export PATH="$PATH:$HOME/.rvm/bin" 更改为 export PATH=$PATH:"$PATH:$HOME/.rvm/bin"，但是当我运行 @ 时，我仍然得到相同的输出和相同的 *warning 987654338@.

那么，谁能建议我如何解决第 3 步和第 4 步中的问题（在我看来）？

编辑#1

*在将$PATH: 伪装成.bash_profile 后，第3 步的警告已解决。更新.bash_profile文件：

source ~/.profile
export PATH=$PATH:/opt/homebrew/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin

export PATH=$PATH:/opt/homebrew/bin:/opt/homebrew/bin:/Users/sarvarkhalimov/.rbenv/shims:/opt/homebrew/bin:/opt/homebrew/sbin:/Users/sarvarkhalimov/.rvm/gems/ruby-2.7.3/bin:/Users/sarvarkhalimov/.rvm/gems/ruby-2.7.3@global/bin:/Users/sarvarkhalimov/.rvm/rubies/ruby-2.7.3/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/sarvarkhalimov/.rvm/bin:/Users/sarvarkhalimov/.rvm/bin

export PATH=$PATH:/opt/homebrew/bin:/opt/homebrew/bin:/opt/homebrew/bin:/Users/sarvarkhalimov/.rbenv/shims:/opt/homebrew/bin:/opt/homebrew/sbin:/Users/sarvarkhalimov/.rvm/gems/ruby-2.7.3/bin:/Users/sarvarkhalimov/.rvm/gems/ruby-2.7.3@global/bin:/Users/sarvarkhalimov/.rvm/rubies/ruby-2.7.3/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/sarvarkhalimov/.rvm/bin:/Users/sarvarkhalimov/.rvm/bin

export PATH=$PATH:/opt/homebrew/bin:/opt/homebrew/bin:/opt/homebrew/bin:/opt/homebrew/bin:/Users/sarvarkhalimov/.rbenv/shims:/opt/homebrew/bin:/opt/homebrew/sbin:/Users/sarvarkhalimov/.rvm/gems/ruby-2.7.3/bin:/Users/sarvarkhalimov/.rvm/gems/ruby-2.7.3@global/bin:/Users/sarvarkhalimov/.rvm/rubies/ruby-2.7.3/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/sarvarkhalimov/.rvm/bin:/Users/sarvarkhalimov/.rvm/bin

export PATH="/usr/local/bin:$PATH"

[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*

!然而

在运行type rvm | head -1 后我仍然得到rvm is a shell function from /Users/sarvarkhalimov/.rvm/scripts/cli 而不是得到rvm is a function

【问题讨论】：

希望这个问题能帮助许多愿意安装 RVM 的 macOS 用户，因为我遇到了这个问题并且暂时无法解决。我在 GitHub 的 RVM 存储库中创建了一个问题，但尚未收到回复。
我认为警告很清楚。由于前 4 个不包含 $PATH 您实际上只是一遍又一遍地覆盖 PATH 变量，而不是扩展它。例如export HELLO=1 && export HELLO=2 && echo $HELLO # 2 因为第二个导出覆盖了第一个但export HELLO=1 && export HELLO=$HELLO:2 && echo $HELLO # 1:2 因为第二个导出添加了系统变量$HELLO
@engineersmnky 谢谢。我已经在第 3 步解决了该警告。但是，在运行type rvm | head -1 而不是获得rvm is a function 之后，我仍然得到rvm is a shell function from /Users/sarvarkhalimov/.rvm/scripts/cli。有什么想法吗？
rvm is a shell function from ... 听起来不错。我不认为你应该有使用它的问题。但是，您应该真正清理bash_profile 中的PATH 定义。您现在将多次插入相同的路径到您的 PATH 变量中。从命令行尝试echo $PATH，你会看到。我建议从您的bash_profile 中删除重复项以进行清理。
@Casper 感谢您的回复。我将终端上的默认 shell 从 zsh 更改为运行 chsh -s /bin/bash 的 bash。在那之后，我意识到我在过去的某个时间也安装了 rbenv，这导致了 $PATH 问题，我相信。因此，在卸载它并重新运行问题中提到的第 5 步后，我成功安装并在运行type rvm | head -1 后得到了rvm is a function。呼）

【解决方案1】：

问题由以下几部分组成：

1. 在.bash_profile 中添加$PATH:。所以，我的.bash_profile 现在看起来像这样（也许可以清理，但不确定。如果你知道怎么做，请在 cmets 中告诉我或留下链接） .

    source ~/.profile
    export PATH=$PATH:/opt/homebrew/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin
    
    export PATH=$PATH:/opt/homebrew/bin:/opt/homebrew/bin:/opt/homebrew/bin:/opt/homebrew/sbin:/Users/sarvarkhalimov/.rvm/gems/ruby-2.7.3/bin:/Users/sarvarkhalimov/.rvm/gems/ruby-2.7.3@global/bin:/Users/sarvarkhalimov/.rvm/rubies/ruby-2.7.3/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/sarvarkhalimov/.rvm/bin:/Users/sarvarkhalimov/.rvm/bin
    
    export PATH=$PATH:/opt/homebrew/bin:/opt/homebrew/bin:/opt/homebrew/bin:/opt/homebrew/bin:/opt/homebrew/sbin:/Users/sarvarkhalimov/.rvm/gems/ruby-2.7.3/bin:/Users/sarvarkhalimov/.rvm/gems/ruby-2.7.3@global/bin:/Users/sarvarkhalimov/.rvm/rubies/ruby-2.7.3/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/sarvarkhalimov/.rvm/bin:/Users/sarvarkhalimov/.rvm/bin
    
    export PATH=$PATH:/opt/homebrew/bin:/opt/homebrew/bin:/opt/homebrew/bin:/opt/homebrew/bin:/opt/homebrew/bin:/opt/homebrew/sbin:/Users/sarvarkhalimov/.rvm/gems/ruby-2.7.3/bin:/Users/sarvarkhalimov/.rvm/gems/ruby-2.7.3@global/bin:/Users/sarvarkhalimov/.rvm/rubies/ruby-2.7.3/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/sarvarkhalimov/.rvm/bin:/Users/sarvarkhalimov/.rvm/bin
    
    export PATH="/usr/local/bin:$PATH"
    
    [[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm" # Load RVM into a shell session *as a function*
    export PATH="/opt/homebrew/bin:$PATH"

2. 我有rbenv，以前安装过，它是另一个 ruby 版本管理器。所以，我不得不按照steps 卸载它。 *注意：删除带有rbenv的行时，请只删除与rbenv相关的部分，而不是整行。

例如，从以下位置删除/Users/sarvarkhalimov/.rbenv/shims:：

export PATH=$PATH:/opt/homebrew/bin:/opt/homebrew/bin:/Users/sarvarkhalimov/.rbenv/shims:/opt/homebrew/bin:/opt/homebrew/sbin:/Users/sarvarkhalimov/.rvm/gems/ruby-2.7.3/bin:/Users/sarvarkhalimov/.rvm/gems/ruby-2.7.3@global/bin:/Users/sarvarkhalimov/.rvm/rubies/ruby-2.7.3/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Users/sarvarkhalimov/.rvm/bin:/Users/sarvarkhalimov/.rvm/bin

3. 我确实将我的默认 shell 终端从 zsh 更改为运行 chsh -s /bin/bash 的 bash。

RVM安装成功verification.

最后，当您按预期运行 type rvm | head -1 时，它会返回 rvm is a function。

这一定有帮助，如果没有，请发表评论。我会尽可能快地提供帮助和响应，我有点成为在 macOS 上安装 RVM 的大师）
