python - 配置不正确 : Error importing module django. contrib.locale: "No module named locale"

Question

我在使用 django 时遇到此错误。

我正在使用 django 国际化。我创建语言文件。我运行服务器没有问题，但是当向网站发出请求时显示以下内容:

Traceback (most recent call last):
      File "/usr/local/Cellar/python/2.7.8_2/Frameworks/Python.framework/Versions/2.7/lib/python2.7/wsgiref/handlers.py", line 85, in run

        module = import_module(module_path)
      File "/Users/mcaste/Developer/Projects/django/venv_python_2_8_django_1_6/lib/python2.7/site-packages/django/utils/importlib.py", line 40, in import_module
        __import__(name)
    ImproperlyConfigured: Error importing module django.contrib.locale: "No module named locale"

我有这个:

MIDDLEWARE_CLASSES = (
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.contrib.locale.LocaleMiddleware',
)

Answer 1

我认为，语言环境中间件应该位于通用中间件之前: docs say that

... And it should come before CommonMiddleware because CommonMiddleware needs an activated language in order to resolve the requested URL.

MIDDLEWARE_CLASSES = (
  'django.contrib.sessions.middleware.SessionMiddleware',
  'django.middleware.locale.LocaleMiddleware',
  'django.middleware.common.CommonMiddleware',
)
