基本上，我在 react-router 文件中有一个动态入口块。 但在 webpack 3 中，无法将 css 从这些入口文件中提取到单独的块中。 因此在 webpack 条目中包含了相同的块名。

现在创建了块，提取了没有重复的 css，并将来自多个入口文件的通用 scss 导入移动到 commonChunks 条目，但我开始收到此错误。 可能是因为我现在指定了两次入口块（一次在 webpack 入口中，另一次在 react-router 文件中）

因此我升级到 3.10 解决了该问题，但现在 css 块中有重复的 css。

因此想知道是否有任何解决方案或替代方法可以在 webpack 3.2 中以单独命名的块中提取 css，或解决 3.10 中的重复 css 问题

错误（仅在生产模式下发生）
