Python+WSGI-无法从目录导入我自己的模块？

Question

我是Python新手，我已经研究了如何从目录/子目录导入自定义模块。例如this和this。

这是我的结构

index.py
__init__.py
modules/
  hello.py
  HelloWorld.py
  moduletest.py

索引.py

# IMPORTS MODULES
import hello
import HelloWorld
import moduletest

# This is our application object. It could have any name,
# except when using mod_wsgi where it must be "application"
def application(environ, start_response):

    # build the response body possibly using the environ dictionary
    response_body = 'The request method was %s' % environ['REQUEST_METHOD']

    # HTTP response code and message
    status = '200 OK'

    # These are HTTP headers expected by the client.
    # They must be wrapped as a list of tupled pairs:
    # [(Header name, Header value)].
    response_headers = [('Content-Type', 'text/plain'),
                       ('Content-Length', str(len(response_body)))]

    # Send them to the server using the supplied function
    start_response(status, response_headers)

    # Return the response body.
    # Notice it is wrapped in a list although it could be any iterable.
    return [response_body]

初始化.py

from modules import moduletest
from modules import hello
from modules import HelloWorld

模块/hello.py

def hello():
    return 'Hello World from hello.py!'

模块/HelloWorld.py

# define a class
class HelloWorld:
    def __init__(self):
        self.message = 'Hello World from HelloWorld.py!'

    def sayHello(self):
        return self.message

模块/moduletest.py

# Define some variables:
numberone = 1
ageofqueen = 78

# define some functions
def printhello():
    print "hello"

def timesfour(input):
    print input * 4

# define a class
class Piano:
    def __init__(self):
        self.type = raw_input("What type of piano? ")
        self.height = raw_input("What height (in feet)? ")
        self.price = raw_input("How much did it cost? ")
        self.age = raw_input("How old is it (in years)? ")

    def printdetails(self):
        print "This piano is a/an " + self.height + " foot",
        print self.type, "piano, " + self.age, "years old and costing\
        " + self.price + " dollars."

但是通过Apache WSGI，我得到了这个错误

[wsgi:error] [pid 5840:tid 828] [client 127.0.0.1:54621] import hello [wsgi:error] [pid 5840:tid 828] [client 127.0.0.1:54621] ImportError: No module named hello

知道我做错了什么吗？

编辑：

index.py
__init__.py
modules/
  hello.py
  HelloWorld.py
  moduletest.py
  User/
    Users.py

您需要在.wsgi文件中设置应用程序的路径，在您的情况下，它似乎是index.py：

import sys

path = '/full/path/to/app'
if path not in sys.path:
   sys.path.insert(0, path)
