我有一个flask应用程序，该应用程序通过apache / mod_wsgi提供服务，并在运行于AWS-EC2 Ubuntu 16.04服务器实例上的Docker容器上运行。
我得到的错误是：

这是我的mod_wsgi文件：
#! /usr/bin/python2.7
import sys
import os
##Add this file path to sys.path in order to import settings
sys.path.insert(0, os.path.join(os.path.dirname(os.path.realpath(__file__)), '../..'))
sys.path = ['/usr/lib/python2.7', '/usr/local/lib/python2.7']
##Add this file path to sys.path in order to import app
sys.path.insert(0, "/home/niramai/application/")
##Create an application for our app
from postProcessing_flask import app as application
这是我的Apache配置设置：
WSGIScriptAlias /postProcess /home/niramai/application/postProcessing_flask.wsgi
WSGIScriptReloading On
WSGIDaemonProcess website processes=2 threads=15 display-name=%{GROUP} python-path=/home/niramai/application/
<Directory /home/niramai/application>
Order allow,deny
Allow from all
</Directory>
这是我的Dockerfile，Docker镜像是基于paraview-osmesa镜像构建的，该镜像使paraview-osmesa失效：

我尝试将python路径添加到WSGIDaemonProcess，并尝试附加sys.path以包括python库。
尝试通过使用“ chmod u + s postProcessing_flask.wsgi”设置组的setgid（小写的“ s”）来更改文件夹的权限。
尝试附加LD_LIBRARY_PATH并在mod_wsgi-express start-server命令中专门设置PYTHONPATH，但没有一个起作用。
我是这个领域的新手，我们将不胜感激。
