如果报错说安装依赖报错，大概率是因为npm源没有设置对，比如我这里安装protobufjs的时候报错：ENOTFOUND
npm ERR! code ENOTFOUND
npm ERR! syscall getaddrinfo
npm ERR! errno ENOTFOUND
npm ERR! network request to https://registry.cnpmjs.org/protobufjs-cli failed, reason: getaddrinfo ENOTFOUND registry.cnpmjs.org
npm ERR! network This is a problem related to network connectivity.
npm ERR! network In most cases you are behind a proxy or have bad network settings.

我刚开始也怀疑是网络问题，但是发现把代理关了也还是不行，然后查看npm源里面是否存在这个依赖包，发现npm官方的源里面是有这个依赖的：protobufjs-cli - npm
查看一下自己的源地址：
npm config get registry发现是淘宝的源地址：https://registry.npm.taobao.org
然后我就把源地址改为了官方源：
npm config set registry https://registry.npmjs.org/最后再试一下就好了：
