背景

我正在index.d.ts上创建我的自定义src/@types/index.d.ts文件。我需要像下面那样合并我的类型。

// src/@types/index.d.ts
declare namespace Admin {
  interface InitialStateFromDB {
    teamSettings: {
      teamPasswords: TeamPassword[],
      teamCount: number
    },
    adminPasswords: string,
    postInfos: PostInfo[] | undefined
  }
  interface InitialState extends Omit<InitialStateFromDB, 'adminPasswords'> {
    adminPasswords: AdminPassword
  }
}

问题

我收到了VSCode Intellisense的错误：Cannot find name 'Omit'.ts(2304)。但是编译效果很好。

因此，我将省略类型设为type Omit<T, K extends keyof T> = Pick<T, Exclude<keyof T, K>>（复制到here中）

编译之后，我又遇到了另一个错误：'Omit' was also declared here.

在这种情况下我该怎么办？只是忽略IntelliSense的错误？

Answer 1

Omit只是最近added in TS 3.5.1，因此您可能正在工作空间中使用尚不支持TS的旧版本。

通过遵循these instructions，确保VS Code工作区使用的是与您正在编译的TypeScript版本相同的TypeScript。只需打开一个TS文件，在VS Code中运行Select TypeScript Version命令，然后选择使用您的工作区版本的TypeScript（应该为3.5.1）

Answer 2

使用打字稿版本 3.5.x

如果您使用的是 Angular 版本 6，请将其升级到 8.2.2

您可以在package.json

中查看以下软件包版本

Answer 3

在vscode中按ctrl + shift + p并键入TypeScript，然后选择“ TypeScript：选择TypeScript版本”

Answer 4

尝试使用 "skipLibCheck": true 作为 tsconfig.json 文件中的 compilerOptions 之一

在打字稿中找不到名称“省略”
