先去python官網(wǎng)下載python3安裝包:www.python.org

找到適合自己機(jī)器版本的包

執(zhí)行命令:

wget https://www.python.org/ftp/python/3.7.3/Python-3.7.3.tgz

安裝相關(guān)編譯工具

yum -y groupinstall "Development tools"
yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel libffi-devel

解壓安裝包:

tar -xvf Python-3.7.3.tgz 

創(chuàng)建編譯文件路徑

mkdir /usr/local/python3 //在local目錄下創(chuàng)建python3目錄
cd /usr/local/Python-3.7.3 //轉(zhuǎn)到解壓目錄下
//配置安裝目錄
./configure --prefix=/usr/local/python3

如果顯示如上圖所示的錯(cuò)誤，只需執(zhí)行：yum -y install gcc
安裝gcc后再次執(zhí)行上述命令即可
編譯源碼

make && make install

配置軟連接

ln -s /usr/local/python3/bin/python3  /usr/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3

檢驗(yàn)：
python3 -V
pip3 -V
