“ ImportError：運行“ django-admin migration”時，沒有名為“ tastypie”的模塊”

Question

嘗試發出“ django-admin migration”命令時，出現以下錯誤堆棧：

Traceback (most recent call last):
File "/usr/bin/django-admin", line 21, in <module>
    management.execute_from_command_line()
File "/usr/lib/python3/dist-packages/django/core/management/__init__.py", line 385, in execute_from_command_line
  utility.execute()
  File "/usr/lib/python3/dist-packages/django/core/management/__init__.py", line 354, in execute
    django.setup()

    apps.populate(settings.INSTALLED_APPS)

    app_config = AppConfig.create(entry)

    module = import_module(entry)

ImportError: No module named 'tastypie'

運行pip list ，將pip list django-tastypie (0.12.1) 。 有人知道django為什么找不到此模塊嗎？

提前致謝！

Answer 1

在項目的settings.py文件中，將tastypie添加到INSTALLED_APPS ：

INSTALLED_APPS = (   
    ...   
    ...
    'tastypie',   
)
