官方下载网站的网址后追加"?system=true&standalone=1"
如 https://www.google.cn/chrome/?system=true&standalone=1

1、目录下新建del.bat,内容为：

DEL /F /A /Q \?\%1
RD /S /Q \?\%1

2、拖动无法删除的文件到del.bat上

export JAVA_HOME=/usr/local/jdk/jdk1.8.0_311
export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PATH:$JAVA_HOME/bin

groupadd tomcat
useradd -g tomcat tomcat
usermod -L tomcat

wget https://dlcdn.apache.org/tomcat/tomcat-9/v9.0.62/bin/apache-tomcat-9.0.62.zip

iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-ports 8080

1、更换npm缓存位置
npm config set prefix "D:\Program Files\nodejsCache\node_global"
npm config set cache "D:\Program Files\nodejsCache\node_cache"

并在系统环境变量中添加 D:\Program Files\nodejsCache\node_global，否则全局安装组件无法使用。

2、安装淘宝cnpm
即将下线
npm install -g cnpm --registry=https://registry.npm.taobao.org
使用这条
npm install -g cnpm --registry=https://registry.npmmirror.com

3、设置npm源为淘宝源，加速下载
npm config set registry https://registry.npmmirror.com

4、执行npm i npm -g 全局更新npm

之后再去安装自己需要的组件

npm install vue-router
