Question

所有，我正在尝试在digitalocean服务器上使用flask / apache部署一个简单的页面。它在本地工作正常，但不在服务器上。

__init__.py包含声明：

from flask.ext.wtf import Form,TextField

try_me.wsgi是：

#!/usr/bin/python
import sys
import logging
logging.basicConfig(stream=sys.stderr)
sys.path.insert(0,"/var/www/try_me/")

from try_me import app as application
application.secret_key = 'Add your secret key'

获得以下错误（来自/var/log/apache2/error.log）：

我能够在python解释器中手动导入（在virtualenv下）：

Python 2.7.3 (default, Jan  2 2013, 16:53:07) 
[GCC 4.7.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from flask.ext.wtf import Form
>>> Form
<class 'flask_wtf.form.Form'>

关于如何在这里进行的任何想法？

解决方案（根据上面的Cathy建议，以及下面的dAnjou），必须从wsgi脚本激活virtualenv。添加activate_this执行解决了问题：

#!/usr/bin/python
activate_this = '/var/www/try_me/venv/bin/activate_this.py'
execfile(activate_this, dict(__file__=activate_this))
import sys
..
