2、解决方案

• 修改镜像即可！
• 推荐使用淘宝的镜像npm config set registry https://registry.npmmirror.com

//1.查看npm镜像设置
npm config get registry

//2.将npm设置为淘宝镜像
npm config set registry npm config set registry https://registry.npmmirror.com

//3.再次查看npm镜像设置
npm config get registry

3、npm镜像仓库替换

//替换镜像的操作
1、查看当前的npm镜像设置：npm config list
2、清空缓存：npm cache clean --force
3、替换镜像地址：npm config set registry https://registry.npmmirror.com

！！！注意：此处修改的镜像用的是npm本身，一般国内用户还是建议使用淘宝镜像，所以推荐还是设置成用淘宝镜像，执行：npm config set registry https://registry.npmmirror.com 【推荐】
