angular - 如何解决错误 TS2304 : Cannot find name 'unknown' in a Angular/dotnet project build using the Okta SDK for angular

Question

当尝试使用 dotnet 后端构建和运行 Angular 项目时，我收到以下错误。

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 Angular 包而发生的。存在于 Okta Angular 示例应用程序中。可以在该示例项目的 app.component.ts 文件中找到此导入的使用。

系统提示我为该导入语句执行的安装包括:

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

所有这些都是在项目本地安装的，并使用 npm 在全局范围内安装。

IDE - Visual Studio 代码

其他互联网帖子表示，这是由于使用的 Typescript 版本存在问题，因为 Typescript 3.0 中添加了“未知”关键字。

我已遵循有关在全局和本地再次更新我的 typescript 版本的所有指南。我还安装了另一篇文章推荐的 tsd - typescript 字典包，但无济于事。我似乎无法克服这个错误消息。

Answer 1

从您的 package.json 看来您仍在使用 typescript@2，因此您可以尝试更新 npm i -D typescript@3 或添加 "skipLibCheck": true 到你的 tsconfig。
