ERROR in ./demo.jsModule not found: Error: Can't resolve 'style' in 'C:\Users\Kim.gao\Desktop\webpack入门\app入门\app'BREAKING CHANGE: It's no longer allowed to omit the '-loader' suffix when using loaders.                 You need to specify 'style-loader' instead of 'style',                 see https://webpack.js.org/guides/migrating/#automatic-loader-module-name-extension-removed @ ./demo.js 1:0-33

解决方法：

require("!style-loader!css-loader!./style.css");
