这里可能发生了什么?这是我的两个不同的Macs的问题—— 一个Eclipse安装和一个Aptana工作室。我第一次同步 DB 时回答“是 ” 创建超级用户后, 我就会得到这些错误。

PyDev (通过终端等) 外的表演同步 db 似乎效果良好。

You just installed Django s auth system, which means you don t have any superusers defined. Would you like to create one now?

Answer 1

错误返回时显示,调用 decode 的电话失败,没有参数:

"/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/contrib/auth/management/init.py", line 85, in get_system_username return getpass.getuser().decode(locale.getdefaultlocale()[1]) TypeError: decode() argument 1 must be string, not None Finished

问题在于 locale.getdefaultlocale () 返回环境变量 LANG (见http://docs.python.org/library/locale.html )。如果您打开终端, 在那里同步工作, 并且输入 echo $LANG , 我猜测你会得到类似 en_US.UTF-8 的东西。同样, 我想象您命令行上的 Python 会返回类似的东西 :

>>> import locale
>>> locale.getdefaultlocale()
( en_US ,  UTF-8 )

然而,如果您在不设置 LANG 环境变量的剪贴板内执行相同的命令,您可获得 < code> (None, None) 。

尝试在 Eclipse 中设置 LANG 环境变量( 运行配置... & gt; 环境), 然后运行同步。您可能需要在变量设定的位置( 即运行配置相对于工程本身) 中玩一下。这样可以解决问题吗?
