看看有没有

没有的话说明没有安装npm 带入的包；

进行npm  install

错误原因是：package.json文件的格式问题。检查属性名称喝属性值是否都用 ；或者未进行保存；

# yarn的安装: #

node.js，默认带有npm；yarn是后来开发和npm属于同一类工具；  
下载node.js，使用npm安装  
npm install -g yarn  
查看版本：yarn --version  
安装node.js,下载yarn的安装程序:  
提供一个.msi文件，在运行时将引导您在Windows上安装Yarn  
Yarn 淘宝源安装，分别复制粘贴以下代码行到黑窗口运行即可  
yarn config set registry https://registry.npm.taobao.org -g  
yarn config set sass\_binary\_site http://cdn.npm.taobao.org/dist/node-sass -g

# cnpm : 无法加载文件 #

你需要安装cnpm，这是阿里的国内镜像

# 安装cnpm #

若需配置淘宝镜像  
npm install -g cnpm --registry=https://registry.npm.taobao.org

尝试到 win+r cmd  ,执行npm i;

重启vs code 终端窗口，终于打开的终端窗口格式；
