在virtualenv中运行Django项目时出错

Question

I have a django project which works fine without virtualenv. But now I'm putting it in a virtualenv and it doesn't run. Without virtualenv:

python manage.py runserver --settings=Janta.settings.local

This works fine. With virtualenv when I do the same as above I get:

Traceback (most recent call last):
  File "manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)
  File "/home/moni/.virtualenvs/janta_proj/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 399, in execute_from_command_line
    utility.execute()
  File "/home/moni/.virtualenvs/janta_proj/local/lib/python2.7/site-packages/django/core/management/__init__.py", line 392, in execute

    self._setup(name)
  File "/home/mon/.virtualenvs/janta_proj/local/lib/python2.7/site-packages/django/conf/__init__.py", line 49, in _setup
    self._wrapped = Settings(settings_module)
  File "/home/moni/.virtualenvs/janta_proj/local/lib/python2.7/site-packages/django/conf/__init__.py", line 132, in __init__
    % (self.SETTINGS_MODULE, e)
ImportError: Could not import settings 'Janta.settings.local' (Is it on sys.path? Is there an import error in the settings file?): No module named celery

This is what comes when I try installing celery in the virtualenv:

Requirement already satisfied (use --upgrade to upgrade): Celery in /usr/local/lib/python2.7/dist-packages
Requirement already satisfied (use --upgrade to upgrade): pytz>dev in /usr/local/lib/python2.7/dist-packages (from Celery)

Requirement already satisfied (use --upgrade to upgrade): amqp>=1.4.0,<2.0 in /usr/local/lib/python2.7/dist-packages (from kombu>=3.0.8,<4.0->Celery)
Cleaning up..

What am I doing wrong?

Answer 1

Using sudo will force everything to install globally, and virtualenv is the solution to that problem. It allows you to create virtual environments which have their own independently installed packages, so you can avoid having everything installed globally.

Recreate the virtualenv, install all of your needed packages using pip install packagename and you should be up and running.

参见输出的最后一行：您在某处芹菜，似乎未安装在virtualenv中。
