抱歉，如果这似乎是之前几个问题的重复，但到目前为止这些问题都没有帮助我：-/

我编写了一个 Flask 应用程序，我试图在 mod_wsgi 和 apache2 下部署它。

我得到以下信息ImportError：

阿帕奇配置：

<VirtualHost *:80>

    ServerName  www.foo.com
    ServerAlias foo.com

    DocumentRoot /Users/admin/Sites/p4p/p4p_jsapp/www

    <Directory /Users/admin/Sites/p4p/p4p_jsapp/www>
    Order allow,deny
    Allow from all
    </Directory>

    WSGIDaemonProcess foo.com user=admin processes=2 threads=15 display-name=%{GROUP}
    WSGIProcessGroup foo.com

    WSGIScriptAlias / /Users/admin/Sites/p4p/p4p_jsapp/pfp/pfp.wsgi

    <Directory /Users/admin/Sites/p4p/p4p_jsapp/pfp>
    WSGIProcessGroup foo.com
    WSGIApplicationGroup %{GLOBAL}
    Order allow,deny
    Allow from all
    </Directory>

</VirtualHost>

pfp.wsgi：

import sys

activate_this = '/Users/admin/Sites/p4p/p4p_jsapp/foo/bin/activate_this.py'
execfile(activate_this, dict(__file__=activate_this))

sys.path.append('/Users/admin/Sites/p4p/p4p_jsapp/pfp')
from PfpServer import app as application

PfPServer.py：

import numpy as np
import pandas as pd
import ujson
from flask import Flask, Response, request, render_template
import traceback

app = Flask(__name__)

# ...

我曾尝试使用和不使用 virtualenv 来查看是否有帮助，但无论如何我都会遇到同样的错误。这里有什么问题？

编辑：为了完全清楚，我安装了 pandas 并且应用程序在调试器中本地运行良好

edit2：好的，解决方案在 sys.path 中 - 我已经安装了最新的 pandas RC，它位于非标准路径上，这就是为什么当我单独添加 std 站点包路径时它不起作用的原因：

sys.path.append('/Users/admin/dev/pandas/pandas-0.11.0rc1')
sys.path.append('/Library/Frameworks/EPD64.framework/Versions/7.3/lib/python2.7/site-packages')

...工作 - 谢谢大家！

我的猜测是 apache 运行的 Python 与您用于测试应用程序的 Python 不同。
