本文主要给大家介绍的关于CentOS7下sqlite3找不到问题的解决方法，分享出来供大家参考学习，下面来一起看看详细的介绍：
Centos7下的nltk启动问题
CentOS7，Python3.6，ipython6.0.0
问题描述
ipython
启动ipython命令
importnltk
爆出以下的错误信息：

从错误信息来分析，可以发现，就是sqlite3找不到而已。
问题分析与解决
那就尝试看看sqlite3是否已经安装：
yumsearchsqlite3

找到了sqlite3-devel，那就安装好了

问题没有解决
重新启动ipython
importnltk
但是问题依然存在，哪里出的问题呢？
问题最终解决
虽然安装了sqlite3的数据库，但是对于ipython的环境来说，确实无法找到sqlite3。
于是，我重新编译，并且安装了一下python3。
注意：这个是在sqlite3安装成功之后，在安装python的运行环境。
于是重新启动ipython，问题消逝，一切正常，本质上就是sqlite3的安装，以及sqlite3与python运行环境之间的匹配的问题。
