django命令找不到命令模块

Question

当我./manage.py process_email在我的应用程序中,我得到ImportError: No module named commands.process_email.

我的目录布局是:

./
??? __init__.py
??? admin.py
??? forms.py
??? management
?   ??? __init__.py
?   ??? commands
?       ??? __init.py__
?       ??? process_email.py
??? models.py
??? views.py

process_email命令的来源是:

from django.core.management.base import BaseCommand, CommandError
from django.conf import settings
from website.event.models import Event

class Command(BaseCommand):

    def handle(self, *args, **options):
        process_email()

def process_email():
    print "processing email" 

和我得到的错误:

(website.com)kings@bob-kings-MacBook ~/code/website.com/website $  > ./manage.py  process_email
Traceback (most recent call last):
  File "./manage.py", line 14, in <module>
    execute_manager(settings)
  File "/Users/kings/code/website.com/lib/python2.6/site-packages/django/core/management/__init__.py", line 438, in execute_manager
    utility.execute()
  File "/Users/kings/code/website.com/lib/python2.6/site-packages/django/core/management/__init__.py", line 379, in execute
    self.fetch_command(subcommand).run_from_argv(self.argv)
  File "/Users/kings/code/website.com/lib/python2.6/site-packages/django/core/management/__init__.py", line 261, in fetch_command
    klass = load_command_class(app_name, subcommand)
  File "/Users/kings/code/website.com/lib/python2.6/site-packages/django/core/management/__init__.py", line 67, in load_command_class
    module = import_module('%s.management.commands.%s' % (app_name, name))
  File "/Users/kings/code/website.com/lib/python2.6/site-packages/django/utils/importlib.py", line 35, in import_module
    __import__(name)
ImportError: No module named commands.process_email 

当我这样做时./manage.py,它确实显示process_email在"可用的子命令:"中.这告诉我manage.py看到process_email.py.此外初始化的.py是空的(我不认为它很重要,但只是FYI).

是__init.py__正确命名？我不确定这是你的树上的拼写错误,还是实际上是这样命名的.

Python处理包含__init__.py模块的目录- 但是,如果该文件不存在,它将不处理该目录 - 因此它不会处理__init.py__或"模块".这个文件是空白的完全没问题 - 但是,如果不是,你也可以从中导入(django做了很多),你也可以定义从模块导出的内容.
