angular - Angular 更新错误为“@angular/core”获取元数据：无效的 URL：127.0.0.1:4200

Question

尝试将我的 Angular 项目从 9.1 版更新到 10 时出现此错误。即使我尝试将另一个项目从 Angular 10 更新到 11 也会出现相同的错误。

你有没有遇到过这个问题？可能是什么问题呢？我该如何解决这个问题？

Your global Angular CLI version (10.1.7) is greater than your local

To disable this warning use "ng config -g cli.warnings.versionMismatch false".
The installed local Angular CLI version is older than the latest stable 
version.
