Question

我正在努力学习django ....

我正在关注一个教程，并且做了一个应用....所以我打开了settings.py文件，我对这些名称进行了更改＃39;和＆＃39; ENGINE＆＃39;，根据教程......这里：

python manage.py syncdb

所以在本教程的后面，它说为了实际制作这样一个文件＆＃34; storage.db＆＃34;这样做：

/Users/angel/django/lib/python2.7/site-packages/Django-1.8.1-py2.7.egg/django/core/management/commands/syncdb.py:24: RemovedInDjango19Warning: The syncdb command will be removed in Django 1.9
  warnings.warn("The syncdb command will be removed in Django 1.9", RemovedInDjango19Warning)

Traceback (most recent call last):

django.db.utils.OperationalError: unable to open database file>

这是结果：

{{1}}

Answer 1

~符号未扩展到您的主目录，因此您必须手动将完整的绝对路径传递到数据库：

'NAME': '/home/yourname/django/bin/django_test/storage.db'

如果django_test是您的django项目的名称，那么最好使用以下代码：

'NAME': os.path.join(BASE_DIR, 'storage.db'),

Django manage.py syncdb不工作
