Question

对不起，如果这似乎是以前几个问题的重复，但到目前为止这些都没有帮助我： - /

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

我得到以下ImportError：

Apache conf：

<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__)

# ...

我尝试过使用带有和不带有virtualenv来查看是否会有所帮助，但无论如何我都会得到同样的错误。这有什么问题？

编辑：只是为了让它完全清楚，我已经安装了pandas并且app在调试器中本地运行良好

edit2：好的，解决方案是在sys.path中 - 我已经安装了最新的pandas RC，它位于非标准路径上，这就是为什么当我只添加std site-packages时它不起作用的原因单独的道路：

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 - 感谢所有人！

我的猜测将是apache正在运行与您用于测试应用程序的Python不同的Python。

（另一个）在mod_wsgi下使用Flask的ImportError
