VS 2015使用旧的TypeScript版本

Question

I am using VS 2015. I've just installed TypeScript 1.6.3, restarted VS 2015 and VS seems to be still using an old tsc version: (btw the setup said [Repair], so I suppose this version was already installed)

I've checked what tsc version I am using via PM console:

Package Manager Console Host Version 3.2.0.10516

Type 'get-help NuGet' to see all available NuGet commands.

PM> tsc -v
Version 1.0.3.0
PM> 

I've also checked my .csproj file and found:

<TypeScriptToolsVersion>1.6</TypeScriptToolsVersion>

and

<Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v$(VisualStudioVersion)\TypeScript\Microsoft.TypeScript.targets" Condition="Exists('$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v$(VisualStudioVersion)\TypeScript\Microsoft.TypeScript.targets')" />

What am I missing?

Answer 1

inside C:\\Program Files (x86)\\Microsoft SDKs\\TypeScript delete all the folders exept 1.7

then run in terminal

tsc -v

if nothing run

npm install -g typescript

and after

tsc -v 

and you should see 1.7 version

Answer 2

The primary reason for this is the fatal combination of...

1. Having multiple versions of TypeScript installed
2. Having more thn one of the versions in your PATH variable

If you go and remove all but the most recent version of TypeScript from the PATH environment variable, that will stop tsc commands picking up the wrong one.
