django web-config azure 给出错误“RuntimeError: populate() is not reentrant”

Question

我通过 GitHub 将本地开发的 Django Web 应用程序部署到 azure 中，当我尝试运行 URL 时，web.config 文件中出现以下错误

 Error occurred while reading WSGI handler:

Traceback (most recent call last):

这是我的 web.config 文件：

          </rule>
        </rules>
      </rewrite>

  </configuration>

我的代码有问题还是我需要安装一些额外的要求？我在尝试在 Azure 中运行 django Web 应用程序时遇到此错误，当我在本地运行我的 Web 应用程序时它工作正常。

RuntimeError: populate() 不可重入

我将我的 django 应用部署到 azure，但没有重现您的问题。据我所知，这意味着其中一个配置不正确或缺少所需的库会引发此填充错误。

我建议您将以下代码添加到您的wsgi.py 文件中，并且应该记录真正的错误，然后您可以检查它。

import os
import time
import traceback
import signal
import sys
from django.core.wsgi import get_wsgi_application

try:
    application = get_wsgi_application()
    print 'WSGI without exception'
except Exception:
    print 'handling WSGI exception'
    # Error loading applications
    if 'mod_wsgi' in sys.modules:
        traceback.print_exc()
        os.kill(os.getpid(), signal.SIGINT)
        time.sleep(2.5)
