Could not import/No module named Django Error with Apache
提问by Noah Clark
I had a small proof of concept set up on a development server on a local machine. I'm now trying to move it over to django on a production server, which I'm using webfaction for. However, now that I'm switched over to apache from the built in django server I get the following:
我在本地机器上的开发服务器上设置了一个小的概念证明。我现在正试图将它移到生产服务器上的 django，我正在使用 webfaction 进行生产。但是，现在我从内置的 django 服务器切换到 apache，我得到以下信息：
ViewDoesNotExist: Could not import orgDisplay.views. Error was: No module named orgDisplay.views
But when check my orgDisplay apps folder there is a view.py in it. What am I doing wrong? I've tried adding the following to my settings.py by suggestion of the django IRC room.
但是当检查我的 orgDisplay apps 文件夹时，里面有一个 view.py。我究竟做错了什么？根据 django IRC 房间的建议，我尝试将以下内容添加到我的 settings.py 中。
import sys
sys.path.append(r"/home/user/webapps/django_project/myproject/orgDisplay")
which is the path to my app.
这是我的应用程序的路径。
any ideas on how to even begin to trouble shoot this?
关于如何开始解决这个问题的任何想法？
Thanks in advance.
提前致谢。

I assume you're using mod_wsgi(which is recommended by Django authors), not mod_python. This is the way you should use your sys.path:
我假设您正在使用mod_wsgi（由 Django 作者推荐），而不是mod_python. 这是您应该使用 sys.path 的方式：
django.wsgi:
django.wsgi：
import os, sys
sys.path.append(r"/home/user/webapps/django_project/myproject/")
os.environ["DJANGO_SETTINGS_MODULE"] = "settings"
sys.stdout = sys.stderr # Prevent crashes upon print
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()
urls.py:
网址.py：
from django.conf.urls.defaults import *
urlpatterns = (
("", include("orgDisplay.urls")),
# ...
)
orgDisplay/urls.py:
orgDisplay/urls.py:
import views
urlpatterns = (
(r'^some_view/$', views.some_view), # It is actually orgDisplay.views.some_view
# many more records ...
)
It is a bad idea to add project dir itself to path since you're be getting name conflicts between multiple projects.
将项目目录本身添加到路径是一个坏主意，因为您会遇到多个项目之间的名称冲突。

I think you're appending the wrong directory to sys.path. I think Python is looking in the .../myproject/orgDisplayfolder for the orgDisplaypackage. Try removing the orgDisplayfrom your string, like this:
我认为您将错误的目录附加到sys.path. 我认为 Python 正在寻找包的.../myproject/orgDisplay文件夹orgDisplay。尝试orgDisplay从字符串中删除，如下所示：
import sys
sys.path.append(r"/home/user/webapps/django_project/myproject")
The other option would be to simply add myproject(or whatever your project is actually called) in the import statement.
另一种选择myproject是在导入语句中简单地添加（或您的项目实际调用的任何内容）。
# instead of "from orgDisplay import views"
from myproject.orgDisplay import views
Also, make sure to restart Apache after every edit.
此外，请确保每次编辑后重新启动 Apache。

looking at manage.py, it does it like so:
查看 manage.py，它是这样操作的：
import sys
from os.path import abspath, dirname, join
from django.core.management import setup_environ
# setup the environment before we start accessing things in the settings.
setup_environ(settings_mod)
sys.path.insert(0, join(PINAX_ROOT, "apps"))
sys.path.insert(0, join(PROJECT_ROOT, "apps"))

Provided your WSGI file is in your project directory, a slightly more flexible way is this:
假设您的 WSGI 文件在您的项目目录中，一个稍微更灵活的方法是：
import os, sys
sys.path.append(os.path.dirname(__file__))
This will enable you to change your project location later without having to modify your WSGI file.
这将使您能够稍后更改项目位置，而无需修改 WSGI 文件。
