Syntax Error: TypeError: path must be a string

环境：vue-cli4 vue3 stylus
yarn serve之后的报错：Syntax Error: TypeError: path must be a string
debug：试过重新安装依赖包等，均无法解决。而后仔细查看报错信息，如下

Syntax Error: TypeError: path must be a string

发现是css-loader的问题，因为之前配置过stylus，所以在vue.config.js中查看了一下配置，果然发现问题，把路径更改正确之后解决。

// vue.config.js
css: {
    
    
    loaderOptions: {
    
    
      // 给 stylus-loader 传递选项
      stylus: {
    
    
        import: '~@/styles/index.styl'  // 此处地址更正
      }
    }
  }

本人在博客中搜寻这个这个报错的解决方式时，发现大多数的这类报错（如下）都是由于css的渲染引起的。如果你有同样问题，不妨排查预处理器的配置、相关包的版本试一试。
