Python Openshift上的Flask框架无法加载模块

因此，我从github上的OS quickstart在OS中创建了一个flask应用程序。该应用程序在我的本地系统上运行良好。当我将应用程序推送到操作系统时，它会生成，但浏览器中出现错误500

如有任何想法或帮助，将不胜感激

以下是应用程序文件中的源代码：

#!/usr/bin/python import os

virtenv = os.environ['APPDIR'] + '/virtenv/'
os.environ['PYTHON_EGG_CACHE'] = os.path.join(virtenv, 'lib/python2.6/site-packages')
virtualenv = os.path.join(virtenv, 'bin/activate_this.py')
try:
    execfile(virtualenv, dict(__file__=virtualenv))
except IOError:
    pass

from run import app as application

以下是run.py文件的源代码

from app import app 
app.run(debug = True)

以下是我的站点哈希ID日志中的错误：

在mod_wsgi下托管时，不应尝试运行Flask内置开发服务器。返回并检查Flask中的mod_wsgi文档，了解您打算做什么

您是否查阅了flask网站上的以下描述：

问题：应用程序给出了权限错误 可能是由于您的应用程序以错误的用户身份运行。确保应用程序需要访问的文件夹具有正确的 设置权限，应用程序以正确的用户和 WSGIDaemonProcess指令的组参数

所以我终于找到了我的代码的错误所在。我的run.py文件中缺少一行，因此错误的文件如下所示：

不正确的文件：

from app import app
app.run()

这是已更正的工作文件：

from app import app
if __name__ == "__main__": #Need this line for Openshift
    app.run()

当部署到Apache之类的生产服务器时，显然需要if语句，因此我终于找到了代码的错误所在。我的run.py文件中缺少一行，因此错误的文件如下所示：

当部署到Apache等生产服务器时，显然需要if语句。正确-问题是，当使用mod_wsgi或其他类似工具时，应用程序将由mod_wsgi启动和管理。Flask.run启动开发服务器。如果您在mod_wsgi加载时没有阻止开发服务器启动，那么Flask的服务器会尝试绑定到一个端口，该端口是它正在运行的用户没有权限执行的，因此出现错误。正确-问题是，当使用mod_wsgi或其他类似工具时，应用程序将由mod_wsgi启动和管理。Flask.run启动开发服务器。如果您在mod_wsgi加载时没有停止dev服务器的启动，那么Flask的服务器会尝试绑定到一个端口——它正在运行的用户没有这样做的权限，因此会出现错误。
