如何安装与旧版 TypeScript 兼容的 @types? [英] How can I install @types compatible with an older version of TypeScript?

问题描述

我的项目使用@types/express 和@types/body-parser 之类的包.最近这些 .d.ts 文件被更新为使用通用默认值，但这意味着这些声明文件现在需要 TypeScript 2.3 或更高版本.

My project uses package like @types/express and @types/body-parser. Recently these .d.ts files were updated to use generic defaults, but that means these declaration files now require TypeScript 2.3 or above.

但是，我的项目仍然使用旧版本的 TypeScript - TypeScript 2.2.如何使用 npm 确保我的项目在不升级的情况下仍然可以理解这些定义文件?

However, my project still uses an older version of TypeScript - TypeScript 2.2. How do I use npm to make sure my project can still understand these definition files without upgrading?

推荐答案

@types 发布者工具实际上根据兼容性标记发布.

The @types publisher tool actually tags releases based on compatibility.

为了能够安装兼容TypeScript 2.2的声明文件，可以写

To be able to install declaration files that are compatible with TypeScript 2.2, you can write

npm install @types/body-parser@ts2.2

它并不总是完美的，但通常可以完成工作.

It's not always perfect, but it'll usually get the job done.
