Does VS Code install TypeScript, and if so: where?

Question

I recently read that installing VS Code also installs the TypeScript compiler. Is this true? If so, where is it installed?

I found a tsc.js file here:

I ran across this issue while attempting to build some TypeScript in Visual Studio Code while following along in @DeborahK's Pluralsight course "Angular with TypeScript".

I came across the same error message in the Visual Studio Code OUTPUT panel.

'tsc' is not recognized as an internal or external command, operable program or batch file.

I had recently done a global installation of TypeScript 1.8.9 from npm.

npm install -g typescript

However, checking the TypeScript compiler version in my cmd shell would show an older version, 1.3.0.

$ tsc -v

To get around this, I removed references from the "Path" variable in my "System variables" (Advanced system settings > Environment Variables... > System variables). I removed the following path:

C:\Program Files (x86)\Microsoft SDKs\TypeScript\1.1\

I learned that the Visual Studio 2013 installation I also had on the same machine included an installation of TypeScript 1.3.0. Cleaning my "Path" variable fixed the output on my TypeScript compiler version check.

Sadly, I still had the issue in Visual Studio Code. The thing that inevitably fixed it for me was a reboot.

If you got this far down in the thread, that's what fixed it for me. YMMV.
