Python 烧瓶和mod_wsgi导入错误

我正在尝试使用mod_wsgi在Ubuntu 16.04上通过apache安装flask应用程序。现在的情况是wsgi脚本无法导入任何python模块

我已经验证了wsgi脚本是可执行的，并且已经用python独立运行了它。我还验证了我的flask应用程序可以自己运行，没有错误。我能够导入我运行的任何其他python程序中的所有模块。我还安装了带有pip和源代码的烧瓶。似乎什么都没用

这是我的错误日志：

这是我的烧瓶程序：

from flask import Flask, json, request, jsonify
import numpy as np

app = Flask(__name__)

@app.route('/')
def hello_world():
    return 'Hello from Flask!'

if __name__ == '__main__':
    app.run()

/var/www/html/flaskapp

包含

flaskapp.py和flaskapp.wsgi

我遗漏了什么？谢谢

编辑：这是我的

我今天正在处理这个问题。如果您使用的是Apache2.4，这是一个简单的更改：

<Directory flaskapp>
        WSGIProcessGroup flaskapp
        WSGIApplicationGroup %{GLOBAL}
        Order deny,allow
        Allow from all

另外，不确定这是否有区别，但我的目录是apache配置中的完整路径：

    Alias /static /var/www/appname/app/static/
    <Directory /var/www/appname/app/>

Apache配置文件？通常/etc/apache2/sites enabled/000-default.conf为什么要运行Flask的开发版本？从错误消息看，它似乎缺少一个程序包。我已经编辑了配置文件，我将在稍后发布。我如何运行flask的开发版本？我不认为我丢失了一个包，因为我可以运行

python-flaskapp.py

而不会出现问题。基于错误，我可以尝试

sudo-pip-install-click

。在错误日志中显示

Flask-0.13.dev0-py2.7

。flask的最新稳定版本是0.12，这是我从源代码处安装的flask版本，因为我怀疑我的flask安装在通过pip安装时不起作用。我试着安装click，但它说它已经安装了。
