Question

我正在尝试从我的虚拟环境运行manage.py runserver，当我这样做时，我收到此消息

    Traceback (most recent call last):
      File "./manage.py", line 10, in <module>
        execute_from_command_line(sys.argv)
      File "/Library/Python/2.7/site-packages/django/core/management/__init__.py", line 353, in execute_from_command_line
        utility.execute()
      File "/Library/Python/2.7/site-packages/django/core/management/__init__.py", line 302, in execute
        settings.INSTALLED_APPS
      File "/Library/Python/2.7/site-packages/django/conf/__init__.py", line 55, in __getattr__
        self._setup(name)
      File "/Library/Python/2.7/site-packages/django/conf/__init__.py", line 43, in _setup
        self._wrapped = Settings(settings_module)
      File "/Library/Python/2.7/site-packages/django/conf/__init__.py", line 99, in __init__
        mod = importlib.import_module(self.SETTINGS_MODULE)
      File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/importlib/__init__.py", line 37, in import_module
        __import__(name)
      File "/Users/ray/Desktop/sub_desk/myheroku/practice/src/gettingstarted/__init__.py", line 4, in <module>
        from .celery import app as celery_app
      File "/Users/ray/Desktop/sub_desk/myheroku/practice/src/gettingstarted/celery.py", line 6, in <module>
        from celery import Celery
    ImportError: No module named celery

我不仅有芹菜，而且还使用了virtenv以外的python 2.7。当我在进入或离开环境时键入哪个python时，它们都来自同一位置，根据搭便车者指导python，它们应该是分开的。这是怎么回事？不应该在虚拟环境中使用python吗？

然后当我尝试pip install django-celery时，我得到了以下内容

Answer 1

首先，您的虚拟环境install Celery：

IOError: [Errno 13] Permission denied:

如果您获得了示例中显示的sudo pip install -U Celery（这表示您拥有this problem，并且您可以/应该按照提供的链接进行解析），请使用：

python manage.py runserver

完成之后：

~/.virtualenvs/<venv_name>/bin/python

并查看是否可以解决您的问题。

注意：

您可以将PyCharm中的项目解释器设置为虚拟环境

Answer 2

在你的virtualenv中安装celery：

pip install django-celery

在你的virtualenv中启动django app：

python manage.py runserver

Answer 3

一个好的检查是在你运行它的任何地方输入pip freeze。它将打印出所有已安装的软件包。

Answer 4

以管理员身份运行cmd，它一直对我有用。

Answer 5

请尝试删除'/Library/Python/2.7/site-packages/_billiard'并重新安装。

当我运行./manage.py运行服务器时，我得到错误ImportError：没有名为celery的模块
