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

你可以做npm list | grep typescript，如果它是通过npm安装的。

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

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。
