Question

我试图在浏览器中以适当的IP地址打开网站，我收到500内部服务器错误。我正在使用Digital Ocean和带有apache2的Ubuntu 14.04服务器。我收到500错误后运行

$ tail -f /var/log/apache2/error.log

然后我得到以下

    ImportError: No module named pymysql

然后我跑

user@crimemap:~# /var/www/crimemap/crimemap.wsgi

并获取

/var/www/crimemap/crimemap.wsgi: line 1: import: command not found
/var/www/crimemap/crimemap.wsgi: line 2: syntax error near unexpected token `0,'
/var/www/crimemap/crimemap.wsgi: line 2: `sys.path.insert(0, "/var/www/crimemap")'

我环顾四周，无法弄清楚语法错误？

这就是crimemap.wsgi的样子。

import sys
sys.path.insert(0, "/var/www/crimemap")
from crimemap import app as application

当我导入pymysql或其他.py文件时，我没有错误？

user@crimemap:~# python

>>> import pymysql
>>>

我尝试在wsgi文件中添加一个shebang line和python路径，以确保它是可执行的。没有。确保默认文件不干扰，没有。我对此非常陌生，所以它可能是一个完全愚蠢的解决方案。如果是这样，我道歉，但我到处寻找。

看起来apache / mod_wsgi使用了“不同的”python。

您能否首先尝试找出mod_wsgi使用的是哪个python？ https://code.google.com/archive/p/modwsgi/wikis/CheckingYourInstallation.wiki
（参见正在使用的Python安装和 Python共享库）。

目标WSGI脚本无法作为Python模块加载 - Flask
