运行npm run start 的时候出现了这个问题
WARNING in ./node_modules/antd/dist/antd.css (./node_modules/css-loader/dist/cjs.js??ruleSet[1].rules[1].oneOf[5].use[1]!./node_modules/postcss-loader/dist/cjs.js??ruleSet[1].rules[1].oneOf[5].use[2]!./node_modules/source-map-loader/dist/cjs.js!./node_modules/antd/dist/antd.css)Module Warning (from ./node_modules/source-map-loader/dist/cjs.js):Failed to parse source map: 'webpack://antd/./components/time-picker/style/index.less' URL is not supported
解决办法：在根目录创建一个.env文件
然后写上以上 GENERATE_SOURCEMAP=false
