Pycharm中识别的Python包，而不是termin中的

Question

Django项目导入Django的机器上的一切。不过，在我的Linux Ubuntu笔记本电脑上，Pycharm可以在编辑器中识别出这个包，它列在项目的解释器包中，但无法从命令行识别：

    simon@Simon-Swanky:~/PycharmProjects/tcspt$ python manage.py check
Traceback (most recent call last):
  File "manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)
  File "/home/simon/.local/lib/python2.7/site-packages/django/core/management/__init__.py", line 353, in execute_from_command_line
    utility.execute()
  File "/home/simon/.local/lib/python2.7/site-packages/django/core/management/__init__.py", line 327, in execute
    django.setup()
  File "/home/simon/.local/lib/python2.7/site-packages/django/__init__.py", line 18, in setup
    apps.populate(settings.INSTALLED_APPS)
  File "/home/simon/.local/lib/python2.7/site-packages/django/apps/registry.py", line 108, in populate
    app_config.import_models(all_models)
  File "/home/simon/.local/lib/python2.7/site-packages/django/apps/config.py", line 202, in import_models
    self.models_module = import_module(models_module_name)
  File "/usr/lib/python2.7/importlib/__init__.py", line 37, in import_module
    __import__(name)
  File "/home/simon/PycharmProjects/tcspt/assetmanage/models.py", line 3, in <module>
    from imagekit.models import ProcessedImageField
ImportError: No module named imagekit.models

它似乎是在python2的包中查找的，但是我在这个项目中使用了python3。我尝试了一些方法，比如将路径添加到项目变量中，但到目前为止，我无法使其工作。在

尝试从python 2的shell导入imagekit：

尝试从python 3的shell导入imagekit：

>>> import imagekit
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.5/dist-packages/imagekit/__init__.py", line 2, in <module>
    from . import conf

    class ImageKitConf(AppConf):

    new_class._configure()
  File "/usr/local/lib/python3.5/dist-packages/appconf/base.py", line 100, in _configure
    value = getattr(obj._meta.holder, prefixed_name, default_value)
  File "/home/simon/.local/lib/python3.5/site-packages/django/conf/__init__.py", line 55, in __getattr__
    self._setup(name)
  File "/home/simon/.local/lib/python3.5/site-packages/django/conf/__init__.py", line 41, in _setup
    % (desc, ENVIRONMENT_VARIABLE))
django.core.exceptions.ImproperlyConfigured: Requested setting IMAGEKIT_DEFAULT_CACHEFILE_BACKEND, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

如果您使用的是python3，那么应该使用python3 manage.py check。使用虚拟环境可能更好，在这种情况下，您可以在运行python manage.py check之前激活该虚拟环境。在

在Python3shell中导入失败，因为您没有设置DJANGO_SETTINGS_MODULE环境变量（有关详细信息，请参见the docs）。最简单的修复方法是使用Django shell，它为您处理这些问题。在

$ python3 manage.py shell
>>> import imagekit
