centos安裝python3.7

准備工作

准備gcc環境和其他依賴包【python3.7以上的需要】

1.yum -y install gcc

2.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

 

開始安裝

1.下載安裝包

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

 

2.解壓安裝包

tar -zxvf Python-3.7.3.tgz

 

3.新建文件夾，存儲python3.7.3整個環境

mkdir /usr/local/python3

 

4.進入剛才解壓的3.7.3文件夾

cd Python-3.7.3

 

5.開始進行編譯

./configure --prefix=/usr/local/python3

make && make install

 

6.查看環境變量

cd /usr/bin

ll python*

 

7.建立軟鏈接[不能建立和原有環境變量沖突的鏈接]

ln -s /usr/local/python3/bin/python3.7 /usr/bin/python3

ln -s /usr/local/python3/bin/pip3.7 /usr/bin/pip3

 

8.輸入python3驗證
