Question

我在使用mod_wsgi在apache2上部署烧瓶应用程序时遇到问题。错误日志和配置文件如下。我总是得到内部服务器错误。这与How to solve import errors while trying to deploy Flask using WSGI on Apache2非常相似，但出于某种原因，那里提出的解决方案在这里没有用。

bitcones.wsgi

#!/usr/bin/python
import sys
sys.path.insert(0,"/var/www/bitcones")
from bitcones import bitcones as application

apache虚拟主机文件

<VirtualHost *:80>
    ServerName <my-server-name>
    ServerAdmin <my-email>
    WSGIDaemonProcess bitcones user=<my-username> group=<my-username> threads=5
    WSGIScriptAlias / /var/www/bitcones/bitcones.wsgi

<Directory /var/www/bitcones>
    WSGIProcessGroup bitcones
    WSGIApplicationGroup %{GLOBAL}
    Order deny,allow
    Allow from all
</Directory>

我的应用树的一部分（一切都在/ var / www / bitcones /下）

├── bitcones
│   ├── analysis

│   ├── bitcones.py
│   ├── static

└── bitcones.wsgi

这应该足以弄清楚为什么我有这个导入错误。如果需要任何其他文件/配置，请询问。我在失去理智。

谢谢！

编辑：我只想补充说我正在遵循本指南：http://flask.pocoo.org/docs/0.10/deploying/mod_wsgi/

Answer 1

设置mod_wsgi在安装libapache2-mod-wsgi（python 2）或libapache2-mod-wsgi-py3（python 3）时使用的Python版本。我猜你会用你所描述的Python 2，因为使用python 3是比2更慎重的选择。但我不认为这是你的问题。我认为这是一个导入问题，就像格雷厄姆所说的那样。

我建议您使用from bitcones.analysis.statistics import purity_statistics作为导入语句。

在apache2
