ImportError:没有名为web的模块

时间:2013-01-27 06:43:29

标签: python mod-wsgi web.py

当我尝试使用apache运行web.py应用程序时,我在mod_wsgi错误日志文件中收到此错误。我已在我的共享主机上成功安装web.py,我可以确认我可以在本地导入它:

>>> import web
>>> web.application(('/', 'test'), globals())
<web.application.application instance at 0x1f8d3b0>

我也可以运行内置服务器并成功将页面提供给我的网站。

我可以确认mod_wsgi模块正在apache中工作,因为我可以使用wsgi应用的手动编码来提供网页。

我在ImportError: No module named web文档http://webpy.org/install#apachemodwsgi上尝试了web.py错误消息的建议方法,即添加:

abspath = os.path.dirname(__file__)
sys.path.append(abspath)
os.chdir(abspath)

import web

我还添加了http.conf文件中建议的Files标记,这似乎是多余的,因为我已经设置了htdocs目录,但无论如何。我的httpd.conf文件位于下方,我已重新启动apache并仍然收到导入错误消息。

首先,你的apache mod_wsgi似乎是用python 3编译的,web.py不支持。

你的apache conf似乎与我在Webfaction上的那个很相似,如果mod_wsgi的安装程序有python 2.7,你必须选择它而不是python 3。

这就是我典型的conf看起来的样子:

ServerRoot "/home/username/webapps/projectname/apache2"

LoadModule log_config_module modules/mod_log_config.so
LoadModule mime_module       modules/mod_mime.so
LoadModule rewrite_module    modules/mod_rewrite.so
LoadModule alias_module modules/mod_alias.so
LoadModule wsgi_module       modules/mod_wsgi.so

WSGIScriptAlias / /home/username/webapps/projectname/htdocs/code.py/

这是示例code.py

#!/usr/bin/env python
import os
import sys
sys.path.append(os.path.abspath(os.path.dirname(__file__)))
from app import app

if __name__ == "__main__":
    app.run()
else:
    application = app.wsgifunc()
