报错如下错误:
>>> import sqlite3
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python2.7/sqlite3/__init__.py", line 24, in <module>

>>> exit()
系统上已经安装了Python-2.7.4，由于要升级nltk模块，升级后出现上述错误，后来发现_SQLite3出现问题，百度、搜狗都找遍了，就是没找到解决办法，后来听一个哥们说直接yum安装SQLite和SQLite-devel，然后重新编译Python，正好手头上有Python-2.7.10，说动手就动手，开始干起来，具体流程如下:
下载python-2.17.10.tar.gz,pip-9.0.1.tar.gz,setuptools-32.1.0.zip 依次安装如下:

yum -y install sqlite selite-devel
tar xf python-2.17.10.tar.gz
cd python-2.17.10
python setup.py install

tar xf setuptools-32.1.0.zip
