python - Cannot import module -

i have created python web app directory structure:

# cd /usr/local/www/myapp modules layout __init__.py layout.py packages public myapp.wsgi

i have set pythonpath to:

/usr/local/www/myapp/modules:/usr/local/www/myapp/packages

in myapp.wsgi seek do:

import layout

but getting internal server error. why?

this myapp.wsgi (if remove import layout line, works):

import sys import wsgiref import layout def application(environ, start_response): response_status = '200 ok' response_body = 'hello! ' response_headers = [] content_type = ('content-type', 'text-plain') content_length = ('content-length', str(len(response_body))) response_headers.append(content_type) response_headers.append(content_length) start_response(response_status, response_headers) homecoming [response_body]

full error message getting:

output of print sys.path:

first try:

python /usr/local/www/myapp/myapp.wsgi

does load correctly?

if yes, have environment (in ~/.bashrc or such) needed app. try::

# wipe-out env env -i bash # seek 1 time again python /usr/local/www/myapp/myapp.wsgi

verify utilize same python in shell 1 used apache wsgi.

if myapp.wsgi need env load correctly, can 1 of:

set python path in apache, or set in runtime in myapp.wsgi

to set in in wsgi code, here illustration code.

import os, sys extra_dir = os.path.realpath(os.path.join(os.path.dirname(__file__), '..', '..')) if extra_dir not in sys.path: sys.path.append(extra_dir)

put in in origin of myapp.wsgi file.

python apache wsgi
