在Vue项目中引入Echart（使用npm install指令）的时候报错：

PS G:> npm install
npm WARN old lockfile 
npm WARN old lockfile The package-lock.json file was created with an old version of npm,
npm WARN old lockfile so supplemental metadata must be fetched from the registry.
npm WARN old lockfile This is a one-time fix-up, please be patient...
npm WARN old lockfile
npm ERR! code EINVALIDPACKAGENAME
npm ERR! Invalid package name "_@ampproject_remapping@2.1.2@@ampproject": name cannot start with an underscore; name can only contain URL-friendly characters

npm ERR! A complete log of this run can be found in:
npm ERR!     C:\Users\胜胜\AppData\Local\npm-cache\_logs\2022-04-08T15_40_42_658Z-debug.log

原因是package-lock.json这个文件在创建的时候使用了旧版本的npm，其必须从注册表中获取补充元数据。

使用cnpm install指令即可顺利安装相应的依赖。
