Django Shell没有模块命名设置 [英] Django Shell No module named settings

问题描述

我已经通过 mod_wsgi 将Django部署到Apache。从Apache托管时，Django正常运行。但是，我试图通过 manage.py 进行一些维护，但是当我尝试运行它时，我会收到错误：

I've deployed Django to Apache via mod_wsgi. Django is running fine when hosted from Apache. However, I'm trying to do some maintenance via manage.py, but when I try and run it, I get the error:

错误：无法导入设置myproject.settings（是否在sys.path？）：没有模块命名设置

Error: Could not import settings 'myproject.settings' (Is it on sys.path?): No module named settings

user@localhost:~$ cd /usr/local/myproject
user@localhost:/usr/local/myproject$ ls

Django似乎忽略了DJANGO_SETTINGS_MODULE环境变量。

Django seems to be ignoring the DJANGO_SETTINGS_MODULE environment variable.

user@localhost:~$ cd /usr/local/myproject
user@localhost:/usr/local/myproject$ export DJANGO_SETTINGS_MODULE=settings
user@localhost:/usr/local/myproject$ python manage.py shell
Error: Could not import settings 'myproject.settings' (Is it on sys.path?): No module named settings

>>> import settings
>>> 

只是为了确认我没有疯狂，我评论了manage.py中的所有内容，除了导入设置行，并正常运行。

Just to confirm I wasn't going crazy, I commented out everything inside manage.py except the import settings line, and it ran correctly.

我还尝试设置 os。 environ ['DJANGO_SETTINGS_MODULE'] ='settings'和 sys.path.append（'/ usr / local / myproject'）的manage.py，无济于事。

I've also tried setting os.environ['DJANGO_SETTINGS_MODULE'] = 'settings' and sys.path.append('/usr/local/myproject') directly at the top of manage.py, to no avail.

这里发生了什么？为什么Django使用错误的设置模块名称？这是令我疯狂的。

What's going on here? Why is Django using the wrong settings module name? This is driving me crazy.

推荐答案

如果您的根目录名称与您的一个应用程序的名称相同，则可能会发生这种情况。例如这里，我有一个名为 bar 的目录，其中包含一个名为code> bar的应用程序的Django项目：

This can happen if your root directory name is the same as the name of one of your apps. For example here I have a directory called bar containing a Django project with an app also called bar:

Simons-MacBook-Pro ~/temp
$ cd bar

Simons-MacBook-Pro ~/temp/bar
$ ./manage.py shell
Error: Could not import settings 'bar.settings' (Is it on sys.path?): No module named settings

Simons-MacBook-Pro ~/temp/bar
$ ls -l
total 48
-rw-r--r--  1 simon  staff     0 25 Oct 10:46 __init__.py
-rw-r--r--  1 simon  staff   130 25 Oct 10:46 __init__.pyc
drwxr-xr-x  7 simon  staff   238 25 Oct 10:46 bar
-rwxr-xr-x  1 simon  staff   503 25 Oct 10:46 manage.py
-rw-r--r--  1 simon  staff  5025 25 Oct 10:46 settings.py
-rw-r--r--  1 simon  staff  2658 25 Oct 10:46 settings.pyc
-rw-r--r--  1 simon  staff   556 25 Oct 10:46 urls.py

将根目录的名称更改为 foo （或anyt除了 bar 之外的其他选项）解决了这个问题：

Changing the root directory's name to foo (or anything else other than bar) solves the problem:

Simons-MacBook-Pro ~/temp/bar
$ cd ..

Simons-MacBook-Pro ~/temp
$ mv bar foo

Simons-MacBook-Pro ~/temp
$ cd foo

Simons-MacBook-Pro ~/temp/foo
$ ./manage.py shell
