在命令提示符中，只需输入以下命令的1，然后按Enter:

tsc - v 或 tsc - version 或 tsc -版本

注意:请确保已将Typescript添加到环境变量path中 执行命令前，请先查看:如何设置环境 变量。

从Visual Studio 2022开始，Angular/React/Vue有了新的TypeScript/JavaScript项目类型，TypeScript SDK已弃用(但仍然可以通过VS安装程序安装，并带有警告)，Visual Studio应该根据你的项目使用的TypeScript版本提供智能感知和语言支持(npm是通过包指定你正在使用的TypeScript版本的首选方式)。json文件)。

不过，根据这个答案，仍然有关于如何控制/辨别Visual Studio 2022在任何给定时刻支持哪种特定的TypeScript语言版本的问题。

首先，确保在环境变量路径中有以下地址

C:\Program Files (x86)\Microsoft SDKs\TypeScript\2.0

然后打开命令提示符，输入以下命令:

tsc -v

如果你只为Visual Studio安装了TypeScript，那么:

启动Visual Studio命令提示符 输入tsc -v并按Enter

Visual Studio 2017版本15.3及以上将TypeScript版本绑定到单个项目，正如这个答案所指出的:

右键单击解决方案资源管理器中的项目节点 单击“属性” 进入TypeScript Build选项卡

As far as I understand VS has nothing to do with TS installed by NPM. (You may notice after you install TS using NPM, there is no tsc.exe file). VS targets only tsc.exe installed by TS for VS extension, which installes TS to c:\Program Files (x86)\Microsoft SDKs\TypeScript\X.Y. You may have multiple folders under c:\Program Files (x86)\Microsoft SDKs\TypeScript. Set TypeScriptToolsVersion to the highest version installed. In my case I had folders "1.0", "1.7", "1.8", so I set TypeScriptToolsVersion = 1.8, and if you run tsc - v inside that folder you will get 1.8.3 or something, however, when u run tsc outside that folder, it will use PATH variable pointing to TS version installed by NPM, which is in my case 1.8.10. I believe TS for VS will always be a little behind the latest version of TS you install using NPM. But as far as I understand, VS doesnt know anything about TS installed by NPM, it only targets whateve versions installed by TS for VS extensions, and the version specified in TypeScriptToolsVersion in your project file.

你可以在Visual Studio 2013中的NuGet Package Manager Console中运行它。
