在将故事书迁移到最新版本时,我一直在遵循多个指南和在线故障排除。我收到此错误:
BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.
This is no longer the case. Verify if you need this module and configure a polyfill for it.
If you want to include a polyfill, you need to:

我想知道是否有人对此类表格有任何经验,并能够就这种情况下的最佳做法提供一些指导。我使用 Control Container 做了一个非常简单的 stackblitz,只有一个子孩子,不幸的是我无法让它运行https://stackblitz.com/edit/angular-ivy-axbgr5

看起来问题是由 spring-boot-starter-data-jpa 给出的,一旦我删除了依赖项,应用程序就可以正常运行。这是我的完整依赖项列表,但我还需要 JPA 来编写我的持久性类。
