npm 常见错误

**certificate has expired **

request to https://registry.npm.taobao.org/ failed, reason: certificate has expired

解决方式

// 尝试更换镜像源：
npm config set registry https://registry.npmmirror.com

执行 npm config get registry 确认镜像源更换成功，再次尝试npm install。如果还是报错，检查用户目录下.npmrc、.yarnrc、.vuerc这几个配置文件是否还存在旧的镜像地址，如果有一并替换
