Question

我最近将项目从 angular 9 升级到 11，

在我的桌面上运行良好。当我将项目从 repo 拉到我的笔记本电脑（与版本 9 一起使用）时，我在尝试编译时不断收到以下错误。我将全局 Angular CLI 更新为 11.2.11（项目在 11.2.2 上）和 Typescript 到 4.1.5。

这是错误：

Your global Angular CLI version (11.2.11) is greater than your local version (11.2.2). The local Angular CLI version is used.

To disable this warning use "ng config -g cli.warnings.versionMismatch false".

Answer 1

问题在于 tslib 版本未基于 package.json 更新；手动更新后错误消失。
