VSO ASP.NET5 CI构建期间出错 - “您的项目使用不同版本的TypeScript编译器”但我没有使用TypeScript

Question

Suddenly from yesterday (31 August 2015) I have been getting an error on my Visual Studio Online build server when running the continuous integration build. The error occurs during the Build step for my DNX project (Build Foo.Api.xproj) with the following text:

Error : Your project file uses a different version of the TypeScript compiler and tools than is currently installed on this machine. No compiler was found at C:\\Program Files (x86)\\Microsoft SDKs\\TypeScript\\1.4\\1.4\\tsc.exe. You may be able to fix this problem by changing the element in your project file.

The thing is, I'm not using TypeScript in the project at all and a Find on that turns up nothing. I checked with my colleagues and it seems that they are getting similar errors on their continuous integration builds, including on a project that has had no changes at all.

This leads me to believe it is a problem with VSO's build server, perhaps an upgrade. Does anyone know what is going on here and how to fix it?

To provide some context, this is the full output on the build console for this step:

Answer 1

There is a workaround for this posted on MSDN (link below). It worked for me! Basically, you add the following to the MSBuild Arguments section of your build definition:

/p:TscToolExe="..\tsc.exe"

so now my build definition looks like this:

I also opened a new issue on GitHub, but I got a response that it is not an issue with TypeScript but rather an issue with Visual Studio Online, and that the VSO team is aware and working on a fix. Hope this helps!

We are rolling out an update to the VSO build images now.

The issue was due to the order of VS installs and TS updates. Here's the root issue: https://github.com/Microsoft/TypeScript/issues/3493#issuecomment-136722977
