问题描述
这是我。
我有一个OSX Mavericks机器，我使用MacPorts安装Python 2.7和Babel 1.3。
问题是，似乎我在该机器上至少有两个版本的babel，除了我使用MacPort安装的一个，另一个没有安装CLDR语言环境数据文件，所以当我执行以下命令在我的应用程序目录中：
I have an OSX Mavericks machine where I installed Python 2.7 and Babel 1.3 using MacPorts.The problem is that it seems I have at least two versions of babel on that machine and except for the one I installed using MacPort, the other does not have the CLDR locale data files installed, so when I execute the following command in my application directory :
pybabel extract -o ./locale/messages.pot ./
我收到此错误讯息：
[...]

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.
我在我的机器上的这些位置安装了Babel：
I found Babel installed at these locations on my machine :
> 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
> cd /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/babel
> ls

_compat.py dates.py localedata.pyc plural.py util.py
_compat.pyc dates.pyc localtime plural.pyc util.pyc
global.dat messages
这些是我的环境中定义的各种路径：
These are the various paths defined in my environment :
> echo $PATH
/opt/local/bin:/opt/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/git/bin:/Users/XXXXX/.rvm/bin
> echo $PYTHONPATH
> echo $DYLD_FALLBACK_LIBRARY_PATH
> echo $DYLD_LIBRARY_PATH
> echo $DYLD_FALLBACK_FRAMEWORK_PATH
> echo $DYLD_FRAMEWORK_PATH
>
pybabel是使用以下命令创建的别名：
pybabel is an alias i created using the following command :
> alias pybabel='pybabel-2.7'
如何使babel在/ opt / local / Library / Frameworks / Python.framework / Versions / 2.7 / lib / python2.7 / site-packages / babel？
How can I make babel see the Babel version in /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/babel?
推荐答案
我尝试设置PYTHONPATH但出错了...
I tried setting the PYTHONPATH but made a mistake ...
我在egg存档中创建了一个符号链接pybabel在MacPorts版本中使用localedata /似乎有效：
I created a symbolic link in the egg archive pybabel was using to the localedata/ in the MacPorts version and it seems to have worked :
> cd /Library/Python/2.7/site-packages/Babel-2.0_dev_20131218-py2.7.egg/babel
> ln -s /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/babel/localedata localedata
ln: localedata: Permission denied
> sudo ln -s /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/babel/localedata localedata

我仍然无法翻译{％trans％}标签，我发现，你需要明确地使用-F选项在pybabel像这样（即使babel.cfg文件是在当前目录！）：
I still could not get the "{% trans %}" tags translated, I found here that you need to explicitly use the -F option on pybabel like that (even if the babel.cfg file is in the current directory!):
> pybabel -v extract -F babel.cfg -o ./locale/messages.pot ./
帮助这里是我的babel.cfg文件的内容：
And to help here is the content of my babel.cfg file :
[jinja2: **/templates/**.html]
encoding = utf-8
[python: python/*.py]
[extractors]
jinja2 = jinja2.ext:babel_extract
但是我有ImportError：No module named ...错误消息，因为我没有正确配置jinja2和markupsafe。所以，我添加了两个符号链接：
But I got "ImportError: No module named ..." error messages because I did not have jinja2 and markupsafe properly configured. So, I added two symlinks :
> sudo ln -s /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/jinja2 /Library/Python/2.7/site-packages/jinja2
> sudo ln -s /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/markupsafe /Library/Python/2.7/site-packages/markupsafe
它终于工作了！我得到了我的messages.pot文件中的{％trans％}标签的内容！
And it finally worked! I got the content of the "{% trans %}" tags in my messages.pot file!
然而，我不知道这是否是他最好的解决方案...
Yet, I wonder if it is he best solution ...
