Django - 没有名为 _sqlite3 的模块

Question

我在我的 rhel 5 上安装了 django 1.4。默认情况下，rhel 5 中有 python 2.4，但是为了使用 django 1.4，我手动安装了 python 2.7.3开发服务器运行良好，但是当我创建一个新项目并将 settings.py 文件更改为:

'ENGINE': 'django.db.backends.sqlite3','NAME': '/home/oracle/Desktop/test1/my.db'

现在当我给 python2.7 manage.py syncdb 命令时，我得到的错误是:

Traceback (most recent call last):

django.core.exceptions.ImproperlyConfigured: Error loading either

_sqlite3

请指出出路？

Answer 1

你也可能在没有安装sqlite开发库的情况下手动编译了python

所以，做

sudo apt-get install libsqlite3-dev libsqlite3

然后，重新安装python

输入测试

python
>>> import sqlite3
