[django] 创建后台超级用户时出现 TypeError: decode() argument 1 must be string, not None 错误

错误信息如下:

You just installed Django's auth system, which means you don't have any superusers defined.
Would you like to create one now? (yes/no): yes
Traceback (most recent call last):
  File "manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)
  File "/usr/local/lib/python2.7/dist-packages/django/core/management/__init__.py", line 443, in execute_from_command_line

  ...

  File "/usr/local/lib/python2.7/dist-packages/django/contrib/auth/management/commands/createsuperuser.py", line 70, in handle
    default_username = get_default_username()
  File "/usr/local/lib/python2.7/dist-packages/django/contrib/auth/management/__init__.py", line 105, in get_default_username
    default_username = get_system_username()
  File "/usr/local/lib/python2.7/dist-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

执行 python manage.py createsuperuser 也会报上面的错误。

解决办法:

设置正确的系统编码即可。

$ export LC_ALL=en_US.UTF-8
$ python manage.py createsuperuser
Username (leave blank to use 'hello'): admin
E-mail address:
