在Centos7下使用ipython时，发现有个warning，提示无法保存历史记录：
[root@localhost pip-9.0.1]# ipython
/usr/local/lib/python3.6/site-packages/IPython/core/history.py:226: UserWarning: IPython History requires SQLite, your history will not be saved
warn("IPython History requires SQLite, your history will not be saved")

解决方法：在编译python3时，没有安装sqlite-devel；所以会发出此警告。yum安装sqlite-devel后重新编译安装python3即可解决。
#安装sqlite-devel后重新编译安装python3，ipython正常
