第一次尝试使用mod_wsgi作为我的金字塔应用,但是当我尝试访问该网站时,我不断获得ImportError: No module named deploy
在/etc/apache2/sites-available/domain.com

setup_logging(ini_path)
application = get_app(ini_path, 'main')
当我尝试在浏览器中访问domain.com
时,出现The server encountered an internal error or misconfiguration and was unable to complete your request
错误。这是打印出我的错误日志

请注意,第一行上的test
打印来自print 'test'
顶部的手动添加/data/app/lib/python2.6/site-packages/pyramid-1.4-py2.6.egg/pyramid/paster.py
,以确保从我预期的文件中加载$ /bin/pserve app/development.ini --reload
。 ..
现在如果我从pserve启动应用程序
test

test

应用程序成功启动,控制台日志在

我错过了什么?谢谢!

也是正确的用户
print 'test'
根据格雷厄姆的建议 修改,我用paste.py
替换了import paste as p
print p.__path__
/usr/local/lib/python2.6/dist-packages/paste
通过apache访问网站时的打印输出是pyramid.wsgi
,而不是virtualenv。我已经添加了所有可以在线使用的示例,以指向pythonpath
中的virtualenv以及apache配置文件中的{{1}},但显然我仍然没有做到正确。我还在哪里尝试?
答案 0 :(得分:3)
终于解决了。从控制台日志中可以看出,/usr/local/lib
中我的主要python安装已经安装了paste
模块,没有定义deploy
处理程序。
RedBaron对设置WSGIPythonHome
的评论有效,但问题是我有多个应用,所以我不能只将WSGIPythonHome
全局指向特定应用的virtualenv。
无论如何,我再次浏览了virtualenv上的mod_wsgi
个文档(https://code.google.com/p/modwsgi/wiki/VirtualEnvironments#Baseline_Environment)并看到WSGIPythonHome
应指向“处女环境”。字面上
$ virtualenv --no-site-packages BASELINE
然后指向WSGIPythonHome
WSGIPythonHome /usr/local/pythonenv/BASELINE
并将WSGIDaemonProcess
指向我的应用程序的特定virtualenv(我在开始时已经做过)
经验教训:更多关注文档......
最后,我的pyramid.wsgi
可以大大简化为以下
import os
os.environ['PYTHON_EGG_CACHE'] = '/data/app/python-eggs'
from pyramid.paster import get_app, setup_logging
ini_path = '/data/app/app/development.ini'
setup_logging(ini_path)
application = get_app(ini_path, 'main')
答案 1 :(得分:2)
在我的案例中,在虚拟环境中重新安装PasteDeploy修复了问题,但不确定原因。
答案 2 :(得分:1)
该错误表示未安装PasteDeploy包。
