Cannot read property 'numerator' of undefined

报错：[$ node scripts/start.js
Failed to compile.

./node_modules/antd/lib/drawer/style/index.less
Module build failed:

Cannot read property 'numerator' of undefined]([url](url
))

Start by reproducing the failure with `node scripts/start.js` and inspect `node_modules/antd/lib/drawer/style/index.less` around the reported `calc` expression. Confirm the build completes without the `numerator` error; the issue does not mention a test or other project entry point.
