这些错误是由于某些安装尝试添加支持“从@ angular / router”导入{Router}所需的角度包而导致的；” Okta Angular示例应用程序中存在。可以在该示例项目的app.component.ts文件中找到此导入的用法。

系统提示我为该导入语句执行的安装包括：

@angular/router
@angular/core
@angular/common

所有这些都已在项目本地安装，并使用npm在全球安装。

IDE-Visual Studio代码

其他互联网帖子说，这是由于自TypeScript 3.0中添加了“未知”关键字以来，正在使用的Typescript版本存在问题。

我已遵循所有有关在全球和本地再次更新我的打字稿版本的指导。我还安装了tsd-typescript词典程序包，另一篇文章推荐无济于事。我似乎无法摆脱此错误消息。

Answer 1

在您的package.json中，您似乎仍在使用typescript @ 2，因此您可以尝试更新npm i -D typescript@3或将"skipLibCheck": true添加到tsconfig。

Answer 2
