Ruby on rails 雪豹上的$PATH错误，或RoR安装问题？？糟糕的翻译

我在雪豹上安装了ruby、rubygems和rails。当我切换到我的新jekyll项目（~/Documents/blog/jekyll）并运行

[jekyll]$jekyll --server-bash

我得到：

[jekyll]$jekyll --server-bash: /usr/bin/jekyll: /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby: bad interpreter: No such file or directory

感兴趣的可能是：

[jekyll]$which ruby
/usr/local/bin/ruby

我认为问题在于：

[jekyll]$echo $PATH
/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/opt/local/bin:/opt/local/sbin:~/.gem/ruby/1.8/bin:/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/opt/local/bin:/opt/local/sbin:~/.gem/ruby/1.8/bin:/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/opt/local/bin:/opt/local/sbin:~/.gem/ruby/1.8/bin:/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/opt/local/bin:/opt/local/sbin:~/.gem/ruby/1.8/bin:/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/opt/local/bin:/opt/local/sbin:~/.gem/ruby/1.8/bin:/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/opt/local/bin:/opt/local/sbin:~/.gem:/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/opt/local/bin:/opt/local/sbin:/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/opt/local/bin:/opt/local/sbin:/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/opt/local/bin:/opt/local/sbin:/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/usr/local/bin/:/Users/Joe/.gem:/opt/local/bin:/opt/local/sbin:/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/usr/local/bin/:/Users/Joe/.gem:/opt/local/bin:/opt/local/sbin:/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:/usr/local/bin/:/usr/local/bin/gem:/opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin:/opt/local/bin:/usr/local/git/bin:/Users/Joe/Documents/sdks/android-sdk-mac_x86-1.6_r1/tools:/Users/Joe/Documents/sdks/android-sdk-mac_x86-1.6_r1/tools:/Users/Joe/Documents/sdks/android-sdk-mac_x86-1.6_r1/tools:/Users/Joe/Documents/sdks/android-sdk-mac_x86-1.6_r1/tools:/Users/Joe/Documents/sdks/android-sdk-mac_x86-1.6_r1/tools:/Users/Joe/Documents/sdks/android-sdk-mac_x86-1.6_r1/tools:/Users/Joe/Documents/sdks/android-sdk-mac_x86-1.6_r1/tools:/Users/Joe/Documents/sdks/android-sdk-mac_x86-1.6_r1/tools:/Users/Joe/Documents/sdks/android-sdk-mac_x86-1.6_r1/tools:/Users/Joe/Documents/sdks/android-sdk-mac_x86-1.6_r1/tools:/Users/Joe/.gem/ruby/1.8/bin:/Users/Joe/Documents/sdks/android-sdk-mac_x86-1.6_r1/tools:/Users/Joe/.gem/ruby/1.8/bin:/Users/Joe/Documents/sdks/android-sdk-mac_x86-1.6_r1/tools

我的bash_档案的相关部分：

export PATH=/opt/local/bin:/opt/local/sbin:$PATH                            
export MANPATH=/opt/local/share/man:$MANPATH
export PATH=${PATH}:~/Documents/sdks/android-sdk-mac_x86-1.6_r1/tools
export PATH="/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:$PATH"

您的

$PATH

一团糟。您显示

bash\u profile

，我认为它是

~/.bash\u profile

，但您不显示

/etc/profile

或

~/.bashrc

或

/etc/bash.bashrc

。最后两个是在启动非登录交互式shell时获得的，就像使用Terminal.app时获得的一样。“配置文件”的源代码用于登录shell。如果这样设置的话，一个可能会找到另一个

如果您的

PATH=“something:$PATH”

由于上面列出的一个或多个文件相互寻源而重复执行，则可能会导致混乱

但是，“坏解释器”消息的问题可能与

$PATH

无关。这个消息意味着脚本文件中的shebang（在您的例子中，

#！/some/path/to/ruby

我认为）与ruby实际安装的位置不同。这就是为什么你会经常看到看起来像

#的shebang/usr/bin/env-python

因此

env

将通过

$PATH

确定python（在本例中）的位置。

export PATH=/~/.gem:$PATH

在我的~/.bash_档案中，我做到了

是的，我的意思是~/.bash_档案。对其他文件和概要文件没有任何兴趣，但是感谢您提供关于path的信息，并指出ruby的路径在某个时候已经过时了。
