react 使用stylus，配置完无法自动转化成rem，px还是px，没有转化 配置如下： plugins: () => [ require('postcss-flexbugs-fixes'), require('postcss-preset-env')({ autoprefixer: { flexbox: 'no-2009', }, stage: 3, }), // Adds PostCSS Normalize as the reset css with default options, // so that it honors browserslist config in package.json // which in turn let's users customize the target behavior as per their needs. postcssNormalize(), require('postcss-px2rem-exclude')({ remUnit: 37.5 , exclude:/node_modules/i }), ],
