1、下載安裝包
wget https://www.python.org/ftp/python/3.5.0/Python-3.5.0b4.tgz
2、創建安裝路徑
mkdir /usr/local/python3
3、解壓
tar -zvxf Python-3.5.0b4.tgz
4、安裝
進入解壓目錄
./configure --prefix=/usr/local/python3
make
make install
5、更改環境變量
先把舊版本改名
which python
(/usr/bin/python)
mv /usr/bin/python /usr/bin/python2
創建鏈接
ln /usr/local/python3/bin/python3.5 /usr/bin/python
