CentOS7安装Python3.7-优快云博客

1.安装编译相关工具

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
yum install libffi-devel -y

2.下载安装包解压

cd home  # 回到用户目录
wget https://www.python.org/ftp/python/3.7.4/Python-3.7.4.tgz
tar -zxvf Python-3.7.4.tgz

3.编译安装

mkdir /usr/local/python3  # 创建编译安装目录
cd Python-3.7.4
./configure --prefix=/usr/local/python3  # 配置安装位置
make && make install

4.创建软连接

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

5.验证是否成功

python3 --version
# 或者
python3 -V

pip3 --version
# 或者
pip3 -V

6.将python加入环境变量（可选）

# 查看环境变量
echo $PATH 
vim /etc/profile
# 在最后一行加入
PATH=$PATH:/usr/local/python3/bin # 这里的路径取决于安装的python路径
source /etc/profile
