在Windows上使用Apache和mod_wsgi安装金字塔时出现的问题

Question

I am trying to install a pyramid project on windows. The wsgi file contains:

import os, sys

baseDir='D:\myproject\hello'
configFile = os.path.join(baseDir, 'development.ini')

sys.path.append(baseDir)
os.environ['PYTHON_EGG_CACHE'] = '/var/www/.python-eggs'

from pyramid.paster import get_app, setup_logging
setup_logging(configFile)
application = get_app(configFile, 'main')

Here 'hello' is the project name(root). But while accessing it from browser, I get the following error:

 from pyramid.paster import get_app, setup_logging
 [Wed Jan 22 14:32:50 2014] [error] [client 127.0.0.1] ImportError: No module named  pyramid.paster

Can anyone help me to debug it.

According to this pyramid tutorial your environment is rather uncommon and difficult to set up. Nevertheless you need a python environment with pyramid installed. Say hello to virtualenv. You did not mention any details about using it. Below you see how WSGIDaemonProcess is configured to path of site-packages of the Python which mod_wsgi will run. Do not manage sys.path in wsgi.py. Your file wsgi.py should be like

from pyramid.paster import get_app, setup_logging
configFile = 'D:\myproject\hello\develoment.ini'
setup_logging(configFile)
application = get_app(configFile, 'main')

Before running mod_wsgi, run the python interpreter you used to install pyramid and import pyramid code. If that raises ImportError you either use wrong python interpreter or there is no pyramid installed.

from pyramid.paster import get_app, setup_logging

An excerpt from the configuration shown at mod_wsgi tutorial .

WSGIDaemonProcess pyramid user=chrism group=staff threads=4 \
   python-path=/your/path/to/python/lib/python2.X/site-packages
WSGIScriptAlias /myapp /your/path/to/project/pyramid.wsgi

Try starting with pyramid scaffolds to learn basic principles of pyramid applications. There is also detailed instruction about running pyramid on windows .
