Answer 1

是package.json中"chromedriver": "^2.27.2"这个插件的问题，删掉后项目启动成功了
解决办法：
1：关闭代理
npm config set proxy null
2：安装淘宝镜像

step1: npm config set registry https://registry.npm.taobao.org

step2： npm info underscore

3：yarn install 安装node-modules

Answer 2

很明显是开了翻墙的代理，1080端口

Answer 3

$ yarn install
yarn install v1.22.4
