npm不建议不在package.json文件中的软件包发出警告

Question

我正在尝试为Exercism JavaScript tutorial设置工作文件夹，当我运行npm install命令时，我收到以下消息

  

npm WARN已弃用circular-json@0.3.3：CircularJSON仅在维护中，flatted是其后续版本。   npm WARN不推荐使用kleur@2.0.2：如果您希望使用旧语法，请升级到kleur @ 3或迁移到“ ansi-colors”。访问https://github.com/lukeed/kleur/releases/tag/v3.0.0\以获得迁移路径。

当我查看package.json文件时，没有CircularJSON或kleur，所以我想知道为什么会收到警告，并且npm并未安装其中的软件包。这是package.json文件
