我一直在尝试在我的iMac上使用babel（OSX Mavericks，我使用MacPorts安装了python和babel），但是我收到此错误消息：
[...]

raise RuntimeError('The babel data files are not available. '
RuntimeError: The babel data files are not available. This usually happens because you are using a source checkout from Babel and you did not build the data files. Just make sure to run "python setup.py import_cldr" before installing the library.
我无法运行以下命令，因为我在 Mac 上的 .egg 存档中找不到 setup.py 文件
>python setup.py import_cldr
尝试在我下载的另一个版本的 babel 上运行 setup.py 导致此错误，但即使我可以做到，它也不能解决我的问题，我认为：
> python setup.py import_cldr
running import_cldr

关于如何为 .egg 安装安装 CLDR 文件的任何想法？
这是我机器上 babel 包的内容：
> cd /Library/Python/2.7/site-packages/Babel-2.0_dev_20131218-py2.7.egg/
> ls
EGG-INFO babel
> cd babel
> ls
__init__.py core.py localedata.py numbers.py support.py
__init__.pyc core.pyc localedata.pyc numbers.pyc support.pyc
_compat.py dates.py localtime plural.py util.py
_compat.pyc dates.pyc messages plural.pyc util.pyc
以及我尝试的一些命令的结果：
> cd /Library/Python/2.7/site-packages/Babel-2.0_dev_20131218-py2.7.egg/babel
> python setup.py import_cldr
/opt/local/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python: can't open file 'setup.py': [Errno 2] No such file or directory
> python setup.py install
/opt/local/Library/Frameworks/Python.framework/Versions/2.7/Resources/Python.app/Contents/MacOS/Python: can't open file 'setup.py': [Errno 2] No such file or directory
您必须进入它所在的目录，然后键入："Python setup.py 安装"（不带引号）。

我想我正在查看随系统一起安装的 babel 版本......
我发现MacPorts在以下位置安装东西：
/opt/local/
我需要的 cldr 文件似乎位于：
/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/babel/localedata/
我现在需要找到如何在小牛队上正确设置路径......但我的问题似乎是系统没有使用正确版本的 Babel。
感谢您的回答，我将提出一个新问题来帮助我进行路径配置。
