没有名为“_sqlite3”的模块错误

Question

Python 2.6 和 Django 1.6 已安装在服务器 (Suse) 上。 我安装了 Python 3.4 和 Django 1.7。

我可以跑

django-admin.py startproject 嗨

一旦我运行任何与 manage.py 相关的命令，例如

python manage.py syncdb

我会收到这个错误

 File "/usr/local/lib/python3.4/site-packages/django/db/backends/sqlite3/base.py", line 33, in <module>
    from pysqlite2 import dbapi2 as Database
ImportError: No module named 'pysqlite2'

During handling of the above exception, another exception occurred:

django.core.exceptions.ImproperlyConfigured: Error loading either pysqlite2 or sqlite3 modules (tried in that order): No module named '_sqlite3' 

根据Install pysqlite in virtualenv with python3 support Python 3.x 没有公开版本的 pysqlite。

另外，我安装了 sqlite-autoconf-3080704。我仍然收到相同的错误消息。

我该如何解决？

您似乎只安装了最低限度的 Python 3。如果您使用的是 Debian 或 Ubuntu 等基于 Debian 的系统，您可以通过apt-get install python3 安装完整版。
