CSS loader 会把把非根路径的url解释为相对路径， 加~前缀才会解释成模块路径

resolve: { alias: { ‘@static‘: path.resolve(__dirname, ‘src/static‘), ‘@api‘: path.resolve(__dirname, ‘src/api‘), ‘@components‘: path.resolve(__dirname, ‘src/components‘) } }

将

@import ‘@static/less/login.less‘;

更改为：

@import ‘~@static/less/login.less‘;
