Django 和 SQLite3 不起作用

我的问题如下，我从教程开始https://docs.djangoproject.com/en/1.8/intro/tutorial01/，当我在终端输入后，python manage.py runserver出现错误：

Traceback (most recent call last):
  File "/usr/local/lib/python3.4/site-packages/django/db/backends/sqlite3/base.py", line 31, in <module>
    from pysqlite2 import dbapi2 as Database
ImportError: No module named 'pysqlite2'

During handling of the above exception, another exception occurred:

您知道如何修复此问题吗？我看过 stackoverflow 上的帖子，但对我没有帮助。

答案1

已在 OP 的评论中解决：

我已经通过运行sudo python manage.py runserver而不是解决了这个问题python manage.py runserver。

答案2

运行 python 解释器并检查模块是否安装了 sqlite3 模块。如果没有，请通过运行进行安装。

sudo apt-get 安装 python-sqlite

现在运行你的 django 项目

或者按照此链接中的说明进行操作“没有名为‘pysqlite2’的模块”错误
