在路由器上跑django時，運行syncdb命令時出現一下錯誤-------->
[root@DD-WRT erya]$ python2.6 manage.py syncdb Creating tables ...

初步斷定decode()的話，問題應該出現在語言編碼的問題，想到了環境變量，於是設置：
[root@DD-WRT erya]$ export LC_ALL=en_US.UTF-8 [root@DD-WRT erya]$ python2.6 manage.py syncdb Creating tables ... Installing custom SQL ... Installing indexes ... Installed 0 object(s) from 0 fixture(s)
創建superuser:
[root@DD-WRT erya]$ python2.6 manage.py createsuperuser Username (leave blank to use 'root'): shi E-mail address: er@126.com Password: Password (again): Superuser created successfully.
BUG除掉！！！將export LC_ALL=en_US.UTF-8寫入到profile或者.bashrc中即可。
引用：
The immediate resolution for this, assuming you are using bash as your shell:
$ export LC_ALL=en_US.UTF-8
$ export LANG=en_US.UTF-8
This will set your locale for that session, and syncdb will work. You can add this to your profile and make it permanent for your shells.
You can use the locale command to see the current settings, and locale -a to see what locales are available to you. en_US.UTF-8 is a generic safe one, but you may have other preferences.
