Typescript: Updating VS2015 Typescript tools to 1.8 causes unexpected build failure

[stanhuff]

After installing the 1.8.4.0 VS 2015 Typescript tools I'm getting an unexpected build error:

Build: File 'COMPUTE_PATHS_ONLY.ts' not found.

After perusing other issues with this error I dug into

C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v14.0\Typescript

And also found

C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v15.0\Typescript

I don't know if it's related but for giggles I replaced the Microsoft.TypeScript.targets in v14.0 with the same file I found in v15.0 and the issue went away. Is this v15 stuff mis-installed? I don't have a VS v15.

C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v15.0\Typescript is an exact copy of C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v14.0\Typescript. from the discription you provide, looks like C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v14.0\Typescript\Microsoft.TypeScript.targets did not install correctly. what version did you have installed before upgrading to 1.8.4? do you have VS2013 installed on the same machine? what version of VS do you have installed? does a repair on the 1.8.4 installer solve the issue (Add/Remove Program, search for TypeScript , repair)?

[stanhuff]

The most recent version I had was the 1.7.6 version but I had tried the 1.8.1 beta with odd issues that both repair and re-install didn't fix, so I uninstalled 1.8.1 and re-installed 1.7.6. Maybe this left things in a semi-corrupt state. I do have 2013 Professional installed on the same machine although I haven't been using it. Other than that only 2015 Enterprise is present. Regrettably I had not tried to do a repair of the 1.8 install prior to logging the issue.

The targets file was not the only difference but it was the only relevant difference I think. The other difference was that my 14.0 had an 'en' folder in it. The targets file was dated 11/17/2015 6:11pm.

I reverted my 14.0 to the post-1.8 installed state using a stashed copy and tried doing a repair by re-running the installer and clicking repair. It has forced me to reboot this time and the targets file seems to have been properly installed but it has left that 'en' folder around. The build works now as expected without having to mess with anything so it's good enough for me.

Thanks!

I had this exact same problem and I found if I did a repair install of Typescript 1.7 followed by a repair install of Typescript 1.8 it was fixed. Thanks for posting this. I suspect I earlier installed the Typescript versions IN THE WRONG ORDER which created my problem.

This is a duplicate of #7445

I encountered this problem as well today.

The solution that worked for me was to copy the _TypeScript_ folder from:
C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v15.0
into:
C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v14.0

HT to @stanhuff

P.S. Is v15.0 even a thing yet?

This error comes after installing TypeScript version 2.0.3 for me. I fixed it as per the @mhegazy suggestion by copying exact TypeScript folder from v15.0 to v14.0.

The part of the problem started for me after installing Visual studio 2017. I tried @mrcrowl solution and it worked for me.

Ditto to what @rajeshghaywat posted. I also tried @mrcrowl solution, restarted visual studio, and my problem was solved.
