第一次尝试在我的金字塔应用程序中使用 mod_wsgi,但是ImportError: No module named deploy
当我尝试访问该站点时,我一直得到一个
在我的/etc/apache2/sites-available/domain.com
<VirtualHost *:80>
ServerName domain.com
ServerAlias www.domain.com
ServerAdmin admin@domain.com
DocumentRoot /data/app

在/data/app/pyramid.wsgi
venv = '/data/app/bin/activate_this.py'
execfile(venv, dict(__file__=venv))
ALLDIRS = ['/data/app/lib/python2.6/site-packages']

site.addsitedir('/data/app/lib/python2.6/site-packages')
sys.path.append('/data/app/app')
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')
当我尝试domain.com
在浏览器中访问时,The server encountered an internal error or misconfiguration and was unable to complete your request
出现错误。这是我的错误日志的打印结果

请注意,test
第一行的打印是我print 'test'
在顶部手动添加的,/data/app/lib/python2.6/site-packages/pyramid-1.4-py2.6.egg/pyramid/paster.py
以确保它是从我期望的文件中加载的...
现在如果我从 pserve 启动应用程序
$ /bin/pserve app/development.ini --reload
应用启动成功,控制台日志如下
test
Starting subprocess with file monitor
test
Starting server in PID 9132.
serving on http://0.0.0.0:6543
我也试过直接进入python导入paster.py,也没问题
$ cd /data/app/lib/python2.6/site-packages/pyramid-1.4-py2.6.egg/pyramid/
$ /data/app/bin/python
Python 2.6.5 (r265:79063, Oct 1 2012, 22:04:36)

>>> import pyramid.paster as p
test
>>> print p.__file__
/data/app/lib/python2.6/site-packages/pyramid-1.4-py2.6.egg/pyramid/paster.pyc
>>>
权限也应该没问题
$ ls /data/app -l

我错过了什么?谢谢!
编辑
www-data
也是正确的用户

根据格雷厄姆的建议进行编辑print 'test'
,我用paste.py
import paste as p
print p.__path__
通过 apache 访问站点时的打印输出是/usr/local/lib/python2.6/dist-packages/paste
,而不是 virtualenv。我已经添加了所有我可以在线很好地指向我的 virtualenvpyramid.wsgi
以及pythonpath
apache 配置文件中的示例,但显然我仍然没有做对。我还能在哪里尝试?
