我最近一直在努力将我的Flask应用部署到AWS ElasticBeanstalk。我对网络项目和AWS都很陌生,所以每天都很艰难。每隔一段时间我就会将我的项目部署到EB(过去我能够解决问题)但是由于我将我的应用程序从单片application.py
重组为更加结构化的方法,我一直在努力。部署本身已成功,但我遇到了500错误。日志说:
[Wed Apr 19 00:11:57.895790 2017] [:error] mod_wsgi (pid=15947): Target WSGI script '/opt/python/current/app/app/members/views.py' cannot be loaded as Python module.

我的应用结构是:
myApp/ runServer.py requirements.txt app/ __init__.py config.py static/ members/ __init__.py views.py models.py templates/
我的.ebextensions/<env-name>.config
包含:
option_settings: "aws:elasticbeanstalk:container:python": WSGIPath: app/members/views.py
最后,我的views.py
文件包含我的所有网址路由。我确保所有的函数名都是一样的。
有人知道我在看什么样的问题/解决方案吗?我可以提供更多信息来帮助吗?
谢谢!
修改:将def index()
中的views.py
功能更改为def newFunctionForTesting()
会产生AssertionError: View function mapping is overwriting an existing endpoint function: newFunctionForTesting
编辑2:它可能类似于this one,但在这种情况下,建议的解决方案是将所有内容写入单个文件中,这不是我的方法寻找...也许蓝图可以更好地工作......
修改3 :这是我的应用程序的样子。

答案 0 :(得分:0)
我正在关注this示例来设置我的WSGIPath,但是由于@davidism指出了它,我尝试了一种不同的方法并且它有效。我创建了一个app.wsgi
文件,基本上只导入我的应用程序对象,并在WSGIPath: app/app.wsgi
中设置.ebextensions/<env-name>.config
。该应用程序现在通过Elastic Beanstalk成功部署和启动。我的静态资源停止工作,但我必须更新Elastic Beanstalk控制台中Configuration > Software Configuration > Static Files
下静态文件夹的映射。
谢谢!
