让Jenkins可以使用python脚本 环境：前篇的用docker安装Jenkins

1：Jenkins支持python环境

参考文章：https://www.cnblogs.com/yoyoketang/p/12116246.html

1-1：进jenkins容器

进docker容器, 加上-u root 以root用户权限进入容器 docker exec -it -u root 容器id /bin/bash

1-2：容器内部安装python3环境

下载python3安装包 进入容器内部, linux安装python3环境,参考这篇https://www.cnblogs.com/yoyoketang/p/10195102.html

See `config.log' for more details

1-3：报错了需要安装编译环境（no acceptable C compiler found in $PATH）
你可以选择一个个安：

apt-get -y install gcc automake autoconf libtool make apt-get -y install make apt-get -y install zlib apt-get -y install openssl libssl-dev apt-getinstall sudo

也可以直接安装这个：

linuxidc@linuxidc:~/www.linuxidc.com$ sudo apt install build-essential 该命令将安装一堆新包，包括gcc，g ++和make

附带更新国内源：【当时在这个项目上我是没换，你可以你看看换不换】

1-4：make编译安装

./configure --prefix=/var/jenkins_home/python3 --with-ssl
make
make install

如果在make install的时候报错：zipimport.ZipImportError: can’t decompress data; zlib not available

从错误信息分析，就是缺少了zlib的解压缩类库，安装即可 apt-y install zlib* 安装完成之后，重新安装即可，所有的问题都已经正常解决了

1-5：添加软链接
添加python3软链接

ln -s /var/jenkins_home/python3/bin/python3.8 /usr/bin/python ln -s /var/jenkins_home/python3/bin/python3.8 /usr/bin/python3.8

添加pip3软链接

ln -s /var/jenkins_home/python3/bin/pip3 /usr/bin/pip3

1-6：检查环境
输入pip3 和python3检查环境

root@cb8e397d5308:/var/jenkins_home/python3/Python-3.6.8# pip3 root@cb8e397d5308:/var/jenkins_home/python3/Python-3.6.8# python3 Python 3.6.8 (default, Jan 1 2020, 10:15:14) [GCC 6.3.0 20170516] on linux Type “help”, “copyright”, “credits” or “license” for more information. >>> exit()

使用pip3安装一个requests包

pip3 install requests

好了你已经正确安装了环境了！！！

2：Jenkins安装python插件

2-1：安装python插件

2-2：去编写脚本：
