由于缺少 sqlite 无法运行 django?实际上 sqlite 已经安装在我的系统中。
(py1)[mirror@home ci]$ python manage.py runserver
Validating models...

django.core.exceptions.ImproperlyConfigured: **Error loading either pysqlite2 or sqlite3 modules** (tried in that order): No module named _sqlite3
重点是:加载 pysqlite2 或 sqlite3 模块时出错
证明已经安装了 sqlite 的证据:
(py1)[mirror@home ci]$ rpm -qa | grep sqlite
python-sqlite-1.1.7-1.2.1
sqlite-devel-3.3.6-5
sqlite-3.3.6-5
(py1)[mirror@home ci]$ python -V
Python 2.7.3
(py1)[mirror@home ci]$ python manage.py runserver
那么,为什么 python manage.py runserver 失败了?
编辑 1:
现在我知道我还没有构建 sqlite 模块:
(py1)[mirror@home Python-2.7.3]$ python
Python 2.7.3 (default, Sep 23 2012, 21:42:51)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-52)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import sqlite3
Traceback (most recent call last):

from _sqlite3 import *
ImportError: No module named _sqlite3
我发现sqlite代码包含在python源代码中,但是如何构建它?
[mirror@home Python-2.7.3]$ ls Modules/_s
_sqlite/ _sre.c _sre.o _ssl.c _struct.c
(py1)[mirror@home Python-2.7.3]$ ls Modules/_sqlite/

./configure --help | grep sqlite 什么都不返回....
