在Visual Studio 2015上，只需访问:help/about Microsoft Visual Studio 然后你会看到这样的东西:

微软Visual Studio企业2015 版本14.0.24720.00更新1 微软。net框架 版本4.6.01055

...

打印稿1.7.6.0 TypeScript for Microsoft Visual Studio

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.

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。

如果你想知道在一个特定的项目中使用了什么版本的Typescript，去你的package-lock。json文件。你会发现这样的东西:

"typescript": {
      "version": "3.5.3"
}

我有VS2015，我必须用TypeScript 1.7运行一个构建，虽然我有1.8安装通过npm install TypeScript -g有两种方法(至少对我来说他们工作):

到你的.proj文件中，尽可能地添加<TypeScriptToolsVersion>1.7</TypeScriptToolsVersion>。重建,重新运行。如果不行，试试2。 进入“控制面板->系统->高级系统设置->环境变量”。确保你先添加了你想要的TypeScript版本:C:\Program Files (x86)\Microsoft sdk \TypeScript\1.7;C:\Users\serban\AppData\Roaming\npm

这也会影响你的CLI:

$ tsc -v
message TS6029: Version 1.7.5
