centos上安装python2.7和ipthon3.0 或者 python3.5和ipthon5,0

[root@hanye ~]# wget -c
[root@hanye ~]# wget -c
[root@hanye ~]# yum install readline-devel sqlite-devel -y
#这里如果不安装readline-devel，后面编译的python将没有删除功能
#这里如果不安装sqlite-devel，后面的iPython将报错(WARNING: IPython History requires SQLite, your history will not be saved)
