 问题原因：

在系统中同时存在多个不同版本的python。当前系统是由python 2.6.6升级到python 2.7.13而来。

解决办法：

[root@localhost sqlite-autoconf-3150000]# find / -name _sqlite3.so
/usr/lib64/python2.6/lib-dynload/_sqlite3.so
[root@localhost sqlite-autoconf-3150000]# whereis python
python: /usr/bin/python /usr/bin/python2.6 /usr/lib/python2.6 /usr/lib64/python2.6 /usr/include/python2.6 /usr/share/man/man1/python.1.gz

[root@localhost sqlite-autoconf-3150000]# cp /usr/lib64/python2.6/lib-dynload/_sqlite3.so /usr/local/python27/lib/python2.7/lib-dynload
