CentOS7 安装Python3.6.4

本文转载自博客园ESHLkangihttps://www.cnblogs.com/ESHLkangi/p/8545979.html

1、安装依赖环境

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

2、下载Python3.6

新建个/usr/download 文件夹

mkdir /usr/download

在download文件夹下下载安装包(/usr/download )

wget https://www.python.org/ftp/python/3.6.4/Python-3.6.4.tgz

解压文件

tar -xvf Python-3.6.4.tgz

3、安装Python3

创建安装文件的路径

mkdir /usr/local/python3

4、编译(在解压的文件夹下 /usr/download/python3.6.4)

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

5、安装(在解压的文件夹下 /usr/download/python3.6.4)

make
make install

6、创建新版本的软链接

修改旧版本

mv /usr/bin/python /usr/bin/python_bak

创建新的软连接

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

检查python的版本

python -V

7、配置成功后,pip3用不了,需要进一步配置

将/usr/local/python3/bin加入PATH

vim ~/.bash_profile

修改后如下:

# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin:/usr/local/python3/bin

export PATH

保存退出后,执行以下命令,让上一步修改成功

source ~/.bash_profile

完成!
