安装nodejs：
- 在jenkins服务器安装
[root@jenkinsserver ~]# mkdir /home/tools && cd /home/tools
[root@jenkinsserver tools]# wget https://npm.taobao.org/mirrors/node/v12.10.0/node-v12.10.0-linux-x64.tar.gz
[root@jenkinsserver tools]# tar -xf node-v12.10.0-linux-x64.tar.gz -C /usr/local
[root@jenkinsserver tools]# ln -s /usr/local/node-v12.10.0-linux-x64 /usr/local/node
[root@jenkinsserver tools]# echo 'export PATH=/usr/local/node/bin:$PATH' >> /etc/profile
[root@jenkinsserver tools]# source /etc/profile
[root@jenkinsserver tools]# node -v
v12.10.0
优化nodejs：
# 使用国内源会下载的更快一点
[root@jenkinsserver tools]# npm config set registry https://registry.npm.taobao.org
# 检查是否正常
[root@jenkinsserver tools]# npm config get registry
https://registry.npm.taobao.org/升级nodejs版本：
[root@jenkinsserver tools]# npm install n -g
# /usr/local/node-v12.10.0-linux-x64/bin/n -> /usr/local/node-v12.10.0-linux-x64/lib/node_modules/n/bin/n
# + n@6.3.0
# added 1 package from 4 contributors in 0.524s
[root@jenkinsserver tools]# n stable
#
# installing : node-v12.16.1
# mkdir : /usr/local/n/versions/node/12.16.1
# fetch : https://nodejs.org/dist/v12.16.1/node-v12.16.1-linux-x64.tar.xz
# installed : v12.16.1 to /usr/local/bin/node
# active : v12.10.0 at /usr/local/node/bin/node手动构建node环境：
[root@jenkinsserver gitdata]# git clone -b test git@172.18.1.63:charges/charge-ui.git
# Cloning into 'charge-ui'...

[root@jenkinsserver gitdata]# cd charge-ui/
# 安装node
[root@jenkinsserver charge-ui]# npm install
# ......省略一大堆输出
# 打包vue项目
[root@jenkinsserver charge-ui]# npm run build
自动化构建node环境：
[root@jenkinsserver ~]# echo $PATH
/usr/local/node/bin:/usr/local/maven/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin
npm install
rm -rf ./dist/*
npm run build
ls -lsh ./dist/
