When I deploy my project on an Ubuntu Server, using a virtualenv, I got this error :
当我使用 virtualenv 在 Ubuntu 服务器上部署我的项目时，出现此错误：

I don't know why there is this error my configuration works fine with a fresh install... But when I copy my current project, I got Error 500. I tried to deploy "part after part" but I can't find what's wrong.
我不知道为什么会出现这个错误，我的配置在全新安装时可以正常工作......但是当我复制当前项目时，我收到了错误 500。我尝试部署“一部分又一部分”，但我找不到是什么错误的。
Tell me if you need more of my files because I don't really know where is the problem...
告诉我你是否需要更多我的文件，因为我真的不知道问题出在哪里......
Thank you.
谢谢你。

I met the same problem. Finnaly, I found I'm using django 1.7.1 to run a 1.8dev generated project. When I switch back to 1.7.1, and remove ‘django.middleware.security.SecurityMiddleware' in setting.py, it seems ok.
我遇到了同样的问题。最后，我发现我正在使用 django 1.7.1 来运行 1.8dev 生成的项目。当我切换回 1.7.1，并在 setting.py 中删除 'django.middleware.security.SecurityMiddleware' 时，似乎没问题。

So, I found a solution :
所以，我找到了一个解决方案：
'django.middleware.security.SecurityMiddleware'
This line is in MIDDLEWARE_CLASSES, from settings.py. When I delete this line I have no more problems with the security module but I guess this is not a good way to solve the problem ... I guess this line is in relation with the crsf token and things like that.
该行位于 settings.py 中的 MIDDLEWARE_CLASSES 中。当我删除这一行时，安全模块不再有任何问题，但我想这不是解决问题的好方法......我猜这行与 crsf 令牌和类似的东西有关。
Any other idea to fix the problem ?
还有其他解决问题的想法吗？

I ran into this same problem. It turned out that I was inadvertently using my machine's version of django-admin.py to start my Django project, rather than the one installed within the virtualenv. I ended up having to source bin/activateagain after installing django within the virtualenv, before running any of the django-admin commands.
我遇到了同样的问题。结果是我无意中使用了我机器的 django-admin.py 版本来启动我的 Django 项目，而不是安装在 virtualenv 中的那个。source bin/activate在运行任何 django-admin 命令之前，我最终不得不在 virtualenv 中安装 django 之后再次这样做。

use this it worked for me
使用它对我有用
MIDDLEWARE_CLASSES = [
'django.contrib.sessions.middleware.SessionMiddleware',
'django.middleware.common.CommonMiddleware',
'django.middleware.csrf.CsrfViewMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickHymaning.XFrameOptionsMiddleware',
]

I had the same problem when switching my project from another pc. As i didn't like very much the option given to remove the
从另一台电脑切换我的项目时，我遇到了同样的问题。因为我不太喜欢给出的删除选项
'django.middleware.security.SecurityMiddleware'
'django.middleware.security.SecurityMiddleware'
I just created a new project and a new app, change the settings by hand and copy the rest of the files, and it worked :)
我刚刚创建了一个新项目和一个新应用程序，手动更改设置并复制其余文件，它起作用了:)
I'm guessing it has something to do with the secretkey of the project.
我猜这与项目的密钥有关。

If you previously used a virtualenvfor this project make sure that you activate it for the next time that you will use this project source bin/activateor check to see that you use the proper version of django.
如果您之前为此项目使用过virtualenv，请确保在下次使用该项目时激活它，source bin/activate或者检查您是否使用了正确版本的django.
If you want to removesome middlewares then you need to make sure of what you are doing.
如果你想删除一些中间件，那么你需要确定你在做什么。

(myvenv) pip uninstall django==(version)
(myenv) pip install django==(version)
Just it.
只是它。

I guess this happen in django version 1.7.x when you are trying to open project created using django version higher than 1.7.x
当您尝试打开使用高于 1.7.x 的 django 版本创建的项目时，我猜这会发生在 django 1.7.x 版中
removing 'django.middleware.security.SecurityMiddleware'helps but it create another problem 'session error'or something
删除有'django.middleware.security.SecurityMiddleware'帮助，但它会产生另一个问题'session error'或其他问题
to fix this:
解决这个问题：
pip uninstall django==1.7.x //your current version of django installed
pip install django==1.9.x //or version that is compatible with the project
