您好，我在Mac Os 10.6.8上打开终端窗口，因为我正尝试将红宝石更新为1.9.3，终端在打开它时会立即给出以下响应：
-bash: export: /Library/Frameworks/Python.framework/Versions/Current/bin': not a valid identifier

我试图改变自己的道路，但没有成功。我不确定如何解决此问题，并且一直在阅读大量论坛文章。有任何想法吗？
这是bash_profile：

好的，这里的主要问题是您的目录中有空格分隔目录条目，$PATH并且这些空格中有未加引号的变量，这些变量引起混淆bash。
在这种情况下，您想要做的就是将目录添加到您的路径中。正确的语法是PATH="/foo:/bar/baz:$PATH。$PATH在末尾添加表示将其当前值附加到变量的末尾，这样您就不会覆盖已经存在的内容。中的目录$PATH是按顺序读取的，因此如果要最后搜索新目录，请将其添加到开头PATH="$PATH:/foo:/bar"。
另一个问题是您有许多重复的路径。您可以通过运行找到这些
$ echo $PATH | perl -pne 's/:/\n/g' | sort | uniq -d
/bin
/Library/Frameworks/Python.framework/Versions/2.7/bin
/Library/Frameworks/Python.framework/Versions/3.3/bin
/Library/Frameworks/Python.framework/Versions/Current/bin
/sbin
/usr/bin
/usr/local/bin
/usr/sbin
最后，您导出了$PATH多次，这是没有意义的。我删除了所有重复项并修复了语法，最后得到了以下结果：
# Setting PATH for MacPython 2.5
# The orginal version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/Current/bin:${PATH}"
# Setting PATH for Python 2.7
# The orginal version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/2.7/bin:${PATH}"
# Setting PATH for Python 3.3
# The orginal version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/3.3/bin:${PATH}"
# Load RVM into a shell session *as a function*
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"
PATH="/usr/local/git/bin:/usr/X11/bin:/Users/oskarniburski/.rvm/bin:/usr/X11R6/bin:$PATH"
##
# Your previous /Users/oskarniburski/.bash_profile file was backed up
# as /Users/oskarniburski/.bash_profile.macports-saved_2013-09-26_at_17:32:30
##
# MacPorts Installer addition on 2013-09-26_at_17:32:30: adding an appropriate PATH

复制该文件，打开终端并运行以下命令：
/bin/cp ~/.bash_profile ~/bash_profile.bad
/bin/cat > ~/.bash_profile
第一个将备份您当前的数据~/.bash_profile（以防万一）。第二个似乎什么也没做，但是已经~/.bash_profile可以写作了。只需粘贴什么我给上面直接到终端，然后命中Enter，然后CtrlC。那应该使一切恢复正常。
注意：您被指定/bin，/sbin，/usr/bin并/usr/local/bin在你的.bash_profile。这些几乎可以肯定已经存在$PATH，不需要添加。如果缺少它们（echo $PATH查看当前值），请使用我上面描述的语法添加它们。
