Ruby on rails Ruby/RVM安装问题，可能需要重新格式化/bin

我正在尝试安装rvm

我有以下命令

rvm get stable

rvm requirements

rvm要求后的误差为

Warning! PATH is not properly set up, '/usr/local/rvm/gems/ruby-1.9.3-p392/bin' is not at first place,

通过快速的互联网搜索，我做了以下工作

echo $PATH
/opt/local/bin:/opt/local/sbin:/usr/local/rvm/gems/ruby-1.9.3-p392/bin:/usr/local/rvm/gems/ruby-1.9.3-p392@global/bin:/usr/local/rvm/rubies/ruby-1.9.3-p392/bin:/usr/local/rvm/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin:/usr/texbin:/opt/sm/bin:/opt/sm/pkg/active/bin:/opt/sm/pkg/active/sbin

现在我想问题是我在bin文件夹中安装了多个ruby，但是我不知道如何修复它，一个快速的互联网搜索会让我想到这一点

建议我编辑我的.bash_档案

我当前的.bash_配置文件如下所示

##
# Your previous /Users/secret/.bash_profile file was backed up as /Users/secret/.bash_profile.macports-saved_2013-08-19_at_17:35:01
##

#MacPorts Installer addition on 2013-08-19_at_17:35:01: adding an appropriate PATH variable for use with MacPorts.
export PATH=/opt/local/bin:/opt/local/sbin:$PATH
# Finished adapting your PATH environment variable for use with MacPorts.


##
# Your previous /Users/secret/.bash_profile file was backed up as /Users/secret/.bash_profile.macports-saved_2013-08-19_at_17:42:44
##

# MacPorts Installer addition on 2013-08-19_at_17:42:44: adding an appropriate PATH variable for use with MacPorts.
export PATH=/opt/local/bin:/opt/local/sbin:$PATH
# Finished adapting your PATH environment variable for use with MacPorts.

然而，我对编辑完全不熟悉。bash_profile，对做同样的事情犹豫不决，有人能解释一下下面的操作是什么，它将如何解决我的情况吗

export
PATH=$PATH:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/sm/bin:/opt/sm/pkg/active/bin:/usr/local/bin:/opt/sm/pkg/active/sbina

谢谢

编辑：

我试过了

export
PATH=$PATH:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/sm/bin:/opt/sm/pkg/active/bin:/usr/local/bin:/opt/sm/pkg/active/sbina

正如Stephan所建议的，尽管问题依然存在

编辑2：

我也试过了

rvm --debug get head

返回的

升级说明：

  * WARNING: you have 'rvm_configure_env' in /etc/rvmrc, run the following to fix:

      sudo sed -i'' -e "/rvm_configure_env=.*\/opt\/sm/d" /etc/rvmrc
      rvm autolibs smf

我尝试了两个命令，我仍然得到

Warning! PATH is not properly set up, '/usr/local/rvm/gems/ruby-1.9.3-p392/bin' is not at first place,

什么时候

编辑：

尝试

rvm install ruby-head

---

Backup.bash_profile and hack away:p.

export PATH=…

使环境变量

PATH

可用于调用它的

bash

shell生命周期内的所有命令

rvm install ruby-head
