[英]Django ImportError: No module named middleware
我正在使用 Django 版本 1.8 和 python 2.7。 运行我的项目后出现以下错误。
Traceback (most recent call last):

我试过浏览错误但徒劳无功。 我的相同代码在其他机器上运行良好。
通过在项目目录中运行python manage.py shell
打开 python shell。
在 python shell 中一次运行以下命令:
>>> from corsheaders.middleware import CorsMiddleware
>>> from oauth2_provider.middleware import OAuth2TokenMiddleware
>>> from django.contrib.auth.middleware import SessionAuthenticationMiddleware
其中一行应该给你一个如下所示的错误:
Traceback (most recent call last):
File "<console>", line 1, in <module>
ImportError: No module named middleware
给您该错误的行是给您带来问题的缺失模块。
要找到搜索模块的路径,请执行
>>> import sys; sys.path
或者,如果您不知道如何使用 python shell,您可以一次删除settings.MIDDLEWARE_CLASSES
中的以下行,直到您不再收到该错误为止:
'django.contrib.auth.middleware.SessionAuthenticationMiddleware',
'corsheaders.middleware.CorsMiddleware',
'oauth2_provider.middleware.OAuth2TokenMiddleware',
只需重新安装给您错误的软件包即可。
django.contrib.auth.middleware
-> django
corsheaders.middleware
-> corsheaders
oauth2_provider.middleware
-> oauth2_provider
确保在可以找到的位置安装了所有支持包。 我遇到了安装多个 Python 解释器的问题,并且在使用另一个解释器安装包时无意中用一个解释器运行 Django。 我要验证的另一件事是两台机器上的软件包版本相同。 请密切注意corsheaders.middleware.CorsMiddleware
和oauth2_provider.middleware.OAuth2TokenMiddleware
,因为它们不是 Django 的一部分。
对于我的情况,我做了以下事情:
对于我的情况,以下内容已被删除:
