我一直在用WSGI开发部署在Apache服务器上的Django web应用程序，一切都进展顺利。今天，我对我的应用程序的

admin.py

做了一些小改动，试图自定义内置的Django管理界面，但最初出现了一个语法错误（未闭合的括号）。这意味着，当我触摸

wsgi.py

并加载代码（我的虚拟主机上的wsgi以守护程序模式运行）时，我的网站被替换为内部服务器错误，因为wsgi在遇到语法错误时停止

因此我修复了语法错误，用

manage.py check

检查我没有更多的语法错误，并点击

wsgi.py

重新部署。但是我的网站仍然显示一个内部服务器错误！查看Apache日志，我看到的是：

[Sun Nov 23 13:53:36 2014] [error] [client 128.84.33.19] RuntimeError: populate() isn't reentrant

从

registry.py的populate
方法抛出
谷歌搜索此错误消息时，返回的信息少得出奇，Django文档中没有任何信息。显然，如果你在settings.py
中为一个应用命名两次，有时可能会发生这种情况，但我没有这么做。更重要的是，自从网站正常运行以来，我没有更改过settings.py
——我唯一更改的是admin.py

我尝试还原我所做的所有更改，因此我所有的Python代码都恢复到网站工作时的状态——当我尝试让WSGI重新加载代码时，仍然会出现populate（）不可重入的错误
我还尝试在settings.py
的INSTALLED_apps部分对不同的应用程序进行注释，即使只启用了“django.contrib.staticfiles”，错误仍然会发生。奇怪的是，即使我注释掉了所有的应用程序，我仍然会得到错误——Django即使没有加载任何应用程序也会抛出错误
有人知道这里发生了什么吗？或者有没有更好的方法来调试这个错误，因为Apache日志中的回溯是毫无帮助的
注意：我使用的是Django 1.7、Apache 2.2和Python 2.7
 这不是一种反应，而是一种反射
当您升级到django 1.7，出现500错误并重新加载页面时，Apache会说“populate（）不可重入”。
我认为是在加载页面时，Apache加载应用程序所需的所有模块，当错误被处理时，它不会卸载模块。因此，当您重新加载页面时，apache会再次加载这些模块，但它已经加载了。因此，apache说“populate（）不是可重入的”
我有两个操作来纠正这个问题：重新启动apache，或者纠正处理第一个5OO错误的错误
尝试使用以下命令重新启动apache：
sudo service httpd restart

我希望它能帮助您。
我的服务器管理员重新启动了Apache，神奇地解决了这个问题。加载的完全相同的Python文件不会导致populate（），因此不能重入。我甚至尝试加载另一个语法错误的文件，然后修复它，服务器能够加载新文件并正常运行，没有任何问题
我仍然不知道出了什么问题，但我将此标记为已回答，因为问题已解决。（好吧，只要StackOverflow允许我接受我自己的答案，我就会将其标记为已回答。）
更新：当我不小心上传带有语法错误的Python时，继续出现此错误，我找到了一种比重新启动Apache更容易的解决方法。当WSGI开始抛出populate（）不可重入
错误时，我用以下简单函数替换Django项目的WSGI.py
：
def application(environ, start_response):
    if environ['mod_wsgi.process_group'] != '': 
        import signal
        os.kill(os.getpid(), signal.SIGINT)
    return ["killed"]

然后我重新加载我的网站，WSGI守护进程重新启动（我可以通过查看Apache日志来判断，即使网站仍然显示相同的错误）
如果我随后将wsgi.py
更改为正常并再次重新加载，wsgi将成功地拾取我的代码，而不会抛出populate（）不可重入
（假设我这次没有语法错误）。因此，整个Apache不需要重新启动，只需要WSGI进程，我可以在没有root权限的情况下重新启动它。
您可以通过触摸加载过程早期的文件（而不是WSGI.py）来修复它，而无需重新启动Apache。例如，您的设置文件：
$ touch settings.py

我也没有很好地解决这个问题，但我的问题中有更多信息：
我遇到了同样的问题，而我的错误源只是我正在处理的文件中的语法错误。修正输入错误后，populate（）不可重入
错误消失
如果您是从wsgi脚本运行django，那么您可以通过从命令行运行wsgi脚本来识别输入错误。例如：
cd /usr/local/www/wsgi-scripts/
python djangolauncher.wsgi

如果您在使用Google App Engine时遇到此错误，请检查日志中可能导致此错误的其他错误。我得到了：
配置不正确：加载pysqlite2或sqlite3模块时出错（按该顺序尝试）：没有名为\u sqlite3的模块
您不能将SQLite与Google App Engine一起使用，因此注释掉settings.py的DATABASES
部分会停止该错误，并且运行时错误（“populate（）不可重入”）
错误
 我遇到了这个问题，在我回溯我的提交之前，我找不到任何原因的答案。显然，我添加了一个意外导入，因为自动完成，这使设置变得一团糟
#在models.py中找到
从msilib.schema导入SelfReg

在apache错误日志中：
RuntimeError（“populate（）不可重入”）
它在我的windows开发环境中运行良好，但在ubuntu/apache服务器上失败。
在更改此设置的顺序后，我遇到了相同的错误：
MIDDLEWARE_CLASSES = (
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
    'django.contrib.auth.middleware.AuthenticationMiddleware',
    'django.contrib.auth.middleware.SessionAuthenticationMiddleware',
    'django.contrib.messages.middleware.MessageMiddleware',
    'django.middleware.clickjacking.XFrameOptionsMiddleware',
    'django.middleware.security.SecurityMiddleware',
)

在重新启动apache之前，将其放回到订单上，解决了这个问题。
我也遇到了同样的问题，所以我开始四处看看
现在我已经开始工作了
MIDDLEWARE_CLASSES = (
    'django.contrib.sessions.middleware.SessionMiddleware',
    'django.middleware.common.CommonMiddleware',
    'django.middleware.csrf.CsrfViewMiddleware',
