推荐答案

当您运行 ng build 或 ng serve 时，它总是会创建一个类似 styles 的包.bundles.js 只是为了在开发构建上节省一些时间.另一方面，如果你执行 ng build --prod 它会产生 styles.bundle.css.

When you running ng build or ng serve it always creates a bundle like styles.bundles.js just for sake of saving some time on the dev build. From another hand, if you do ng build --prod it will produce styles.bundle.css.

如果您希望为您的开发构建生成 styles.bundle.css 则只需添加 --extract-css 标志，例如 ng serve --extract-css.

If you want styles.bundle.css to be produced for your dev build then just add --extract-css flag e.g ng serve --extract-css.
