我正在尝试使用 webpack v3 来测试长期缓存。当我通过 webpack 构建两次（只是对index.jsx文件进行更改）时，哈希值更改为vendor文件。
webpack.config.js

}首次构建
js/vendor-a674cd02275fdf4760bd.bundle.js 343 kB 1 [emitted] [big] vendor
第二次构建（只是更新index.jsx）
js/vendor-f8d5fc2097878041c158.bundle.js 343 kB 1 [emitted] [big] vendor
即使我只更新了索引文件，两个哈希值也会发生变化。
帮助
任何人都可以帮我检查这个问题吗？谢谢。
