vue项目给less传递参数，出现 Invalid options object. Less Loader has been initialized using an options object that does not match the API schema.

error in ./src/components/BookFooter.vue?vue&type=style&index=0&id=18045bd8&lang=less&scoped=true&

Module build failed (from ./node_modules/less-loader/dist/cjs.js):
