django.core.exceptions.ImproperlyConfigured: The TEMPLATE_DIRS setting must be a tuple. Please fix your settings.

And there is the ligne in my project/settings.py 
TEMPLATE_DIRS = (
"/home/sarfraz/django/crepes_bretonnes/templates/"
)

希望清楚。

Answer 1

在括号之间闭合的值的末尾添加一个逗号，否则它不是 tuple:

TEMPLATE_DIRS = ( "/home/sarfraz/django/crepes_bretonnes/templates/", )

应该可以解决问题。希望对你有帮助。
