这里小编在 npm i less less-loader@5.0.0 -D 或者其他依赖包的时候出现以上错误

可能是npm版本问题报错

解决方法：在命令后面加上

–legacy-peer-deps

–legacy-peer-deps的作用

在NPM v7中，现在默认安装peerDependencies。

在很多情况下，这会导致版本冲突，从而中断安装过程。

–legacy-peer-deps标志是在v7中引入的，目的是绕过peerDependency自动安装；它告诉 NPM 忽略项目中引入的各个modules之间的相同modules但不同版本的问题并继续安装，保证各个引入的依赖之间对自身所使用的不同版本modules共存。
