TRAC管理员thows Tracback错误

Question

我已经在Ubuntu 14.04.1使用以下命令安装Trac系统：

$ sudo apt-get install trac trac-accountmanager trac-graphviz trac-icalviewplugin trac- 
mastertickets trac-wysiwyg trac-wikitablemacro trac-tags trac-customfieldadmin trac- 
datefieldplugin 

我相信这已安装的Trac 1.0.1-2，但是当我运行一个简单的命令如：

$ sudo trac-admin --version 

我得到以下跟踪：

Traceback (most recent call last): 
    File "/usr/bin/trac-admin", line 9, in <module> 
    load_entry_point('Trac==1.0.1', 'console_scripts', 'trac-admin')() 
    File "/usr/lib/python2.7/dist-packages/trac/admin/console.py", line 567, in run 
    translation.activate(locale) 
    File "/usr/lib/python2.7/dist-packages/trac/util/translation.py", line 325, in activate 
    translations.activate(locale, env_path) 
    File "/usr/lib/python2.7/dist-packages/trac/util/translation.py", line 152, in activate 
    t.add(Translations.load(locale_dir, locale or 'en_US', 
AttributeError: 'NullTranslations' object has no attribute 'add' 

我不熟悉Python，任何想法，为什么这是occurr ing将不胜感激。

要解决此问题，您可以升级到Trac 1.0.2或降级到Babel 0.9.6。详情请参阅comment:1:ticket:11621。
