ValidationError：无效的选项对象。CSS Loader已使用与API模式不匹配的选项对象进行了初始化

我@zeit/next-css用来将css文件导入到我的组件和页面文件中，但是却抛出了这个错误

./styles/navbar.css导入此css文件到我的navbar.jsin组件中，出现此错误

ValidationError: Invalid options object. CSS Loader has been initialised using
     an options object that does not match the API schema.
- options has an unknown property 'minimize'. These properties are valid:
   object { url?, import?, modules?, sourceMap?, importLoaders?, localsConvention?, onlyLocals? }

我next.config.js放在哪里package.json是

const withCSS = require("@zeit/next-css");
module.exports = withCSS();

我的包json
