導入錯誤：沒有模塊名爲books.apps（Django的）

Question

我想使用Django創建一個應用程序，但得到了一個錯誤

"ImportError: No module named books.apps" after running:

python manage.py startapp books 

錯誤消息：

Traceback (most recent call last): 
    File "manage.py", line 22, in <module> 
    execute_from_command_line(sys.argv) 
    File "/Library/Python/2.7/site-packages/Django-1.9-py2.7.egg/django/core/management/__init__.py", line 350, in execute_from_command_line 
    utility.execute() 
    File "/Library/Python/2.7/site-packages/Django-1.9-py2.7.egg/django/core/management/__init__.py", line 324, in execute 
    django.setup()

    File "/Library/Python/2.7/site-packages/Django-1.9-py2.7.egg/django/apps/registry.py", line 85, in populate 
    app_config = AppConfig.create(entry) 
    File "/Library/Python/2.7/site-packages/Django-1.9-py2.7.egg/django/apps/config.py", line 116, in create 
    mod = import_module(mod_path) 
    File "/usr/local/Cellar/python/2.7.12_2/Frameworks/Python.framework/Versions/2.7/lib/python2.7/importlib/__init__.py", line 37, in import_module 
    __import__(name) 
ImportError: No module named books.apps 

任何想法什麼地方出了錯？謝謝！

在嘗試啓動應用程序之前，您必須先啓動項目。第一次運行：

python manage.py startproject mysite 

並用您想調用您的項目替換「mysite」。然後運行：

python manage.py startapp books
