Question

我正在使用Windows XP，并使用来自http://www.python.org/ftp/python/2.7/python-2.7.msi

的Python运行时

如果我在独立应用程序中运行，import psycopg2不会给我带来任何麻烦。但是，当来到mod_wsgi + apache时，我将收到以下错误

[Thu Nov 18 14:26:51 2010] [error] [client 127.0.0.1] mod_wsgi (pid=2832): Target WSGI script 'C:/Projects/SandBox/web/script/index.py' cannot be loaded as Python module.

[Thu Nov 18 14:26:51 2010] [error] [client 127.0.0.1] ImportError: cannot import name tz

这是python脚本。

import sys, os
sys.path.append(os.path.dirname(__file__))

import psycopg2

def application(environ, start_response):
    status = '200 OK'
    output = 'Hello World!'

    response_headers = [('Content-type', 'text/plain'),
                        ('Content-Length', str(len(output)))]
    start_response(status, response_headers)

    return [output]

这是httpd.conf文件。

LoadModule wsgi_module modules/mod_wsgi-win32-ap22py27-3.3.so
WSGIScriptAlias / "C:/Projects/SandBox/web/"
<Directory "C:/Projects/SandBox/web">
    AllowOverride None
    Options None
    Order deny,allow
    Allow from all
</Directory>

我查看了归档C:\Python27\Lib\site-packages\psycopg2-2.2.2-py2.7-win32.egg\，有C:\Python27\Lib\site-packages\psycopg2-2.2.2-py2.7-win32.egg\psycopg2\tz.py

我的猜测是Python不知道你的蛋缓存位置（或者没有权限）。你只需要设置它。更多信息 here 。尝试设置WSGIPythonEggs指令。

ImportError：无法导入名称tz（psycopg2）
