解决方案：

一直以为是node_modules文件包出错，

一直在删除 下载

cnpm install 也下了

node 也重新下了

一个下午一直在删除下载

然后发现本地的能运行

再找下原因

原来是config 文件中index.js 里的host: ‘localhost’,被注释掉了！！！

删除重新 安装 步骤

Step1：npm cache clean --force

Step2：rm -rf node_modules

Step3：rm -rf package-lock.json

Step4：npm install

npm install 成功之后再次启动 npm start
