sqlite是否捆绑到Django中？

Question

Django是捆绑sqlite还是单独的模块？

即使通过查看Django源代码也无法解决这个问题:https: //code.djangoproject.com/browser/django/trunk/django/db/backends/sqlite3

Answer 1

你在找这个:

21  try:
22      try:
23          from pysqlite2 import dbapi2 as Database
24      except ImportError, e1:
25          from sqlite3 import dbapi2 as Database
26  except ImportError, exc:
27      from django.core.exceptions import ImproperlyConfigured
28      raise ImproperlyConfigured("Error loading either pysqlite2 or sqlite3 modules (tried in that order): %s" % exc)

它首先尝试导入PySqlite,一个外部模块.如果失败,它会尝试导入Python 2.5+中包含的sqlite3模块.如果既没有安装Python 2.5+也没有安装外部模块,则失败.它不包括自己的副本.
