virtualenv下的django引发重大恐怖

Question

在ubuntu lucid中，我安装了python2.7.5并设置了一个虚拟环境，我在envpy275上输入了终端.In，并使用pip从需求文件中安装了这些软件。

python==2.7.5
Django==1.4.3
South==0.7.6
distribute==0.6.28
dj-database-url==0.2.1
django-registration==0.8
numpy==1.4.1
matplotlib==1.2.0
psycopg2==2.4.6
python-memcached==1.48
simplejson==3.0.7
wsgiref==0.1.2

$workon envpy275
(envpy27)me@ubuntu:~/dev/python/django/myapp$ pip install -r requirements.txt

这会将这些软件安装到~/.virtualenv/envpy275/lib/python2.7/site-packages中。

我的系统在/home/me/Django-1.4上已经有了Django1.4，我的.bashrc文件中有

PYTHONPATH=/home/me/Django-1.4
PYTHONPATH=$PYTHONPATH:/home/me/dev/python/django/myapp

由于我的项目设置文件位于/home/me/dev/python/django/myapp/mysite directory中，因此我按如下方式设置了DJANGO_SETTINGS_MODULE

 (envpy27)me@ubuntu:~/dev/python/django/myapp$ export DJANGO_SETTINGS_MODULE='mysite.setings'

然后，在终端，我尝试运行django服务器

(envpy27)me@ubuntu:~/dev/python/django/myapp$ python manage.py runserver

这会产生以下警告和错误

/home/me/.virtualenvs/envpy275/lib/python2.7/site-packages/pytz/__init__.py:35: UserWarning: 
Module django was already imported from 
    /home/me/Django-1.4/django/__init__.pyc, but /home/me/.virtualenvs/envpy275/lib/python2.7/site-packages

 ImportError: Could not import settings 'mysite.setings' (Is it on sys.path?): No module named setings

Answer 1

您可能有一个拼写错误，您将DJANGO_SETTINGS_MODULE设置为mysite.setings -通常这是指向文件mysite/settings.py的mysite.settings
