linux配置python环境

容器以管理员权限进入：

sudo docker exec -ti -u root 容器ID bash

下载包：
1.wget https://www.python.org/ftp/python/3.9.0/Python-3.9.0.tar.xz

解包：
2.tar -xvJf Python-3.9.0.tar.xz

进入python文件夹，生成编译脚本

3.执行 
 ./configure prefix=var/jenkins_home/python3

ps:一下是容器内安装python环境时需要。

若是报缺少包则需安装依赖包：

apt-get install build-essential -y

apt-get install libncurses5-dev libncursesw5-dev libreadline6-dev -y

apt-get install libdb5.3-dev libgdbm-dev libsqlite3-dev libssl-dev -y

apt-get install libbz2-dev libexpat1-dev liblzma-dev zlib1g-dev -y

apt-get install libssl-dev openssl -y

4.编译：make

cd var/jenkins_home/python3
make && make install

5.设置软连接
ln -s /usr/local/python3/bin/python3.9 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3.9 /usr/bin/pip3

6.并将/usr/local/python3/bin加入PATH

6.1、vim /etc/profile

6.2 、按“I”，然后贴上下面内容：配置环境变量

# vim ~/.bash_profile

# .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

7.让上面修改的文件生效

source ~/.bash_profile

8.检查是否生效

python3 -V

pip3 -V
