Hi Microsoft!

I'm very happy with vscode in general - good work!
However, I'm unable to get embedded TypeScript server to work on Ubuntu 16.04 with Node.js. vscode was installed using the .deb file.

Steps to Reproduce:

1. Install node.js version 6.9.1 LTS
2. npm init
   3: npm install express --save
   4: Create .js file and import any core module (for instance 'express' or 'fs'.

Recieving the following error in output:

[Info - 3:14:09 PM] Using tsserver from location: /usr/share/code/resources/app/extensions/typescript/node_modules/typescript/lib/tsserver.js
[Error - 3:14:22 PM] 'completions' request failed with error.

I believe this issue was fixed on the TS side by microsoft/TypeScript@6ea5c22 which is not present in TS 2.0.10 . We should pick it up in ts 2.1.x (I confirmed that it is already in 2.1.1).

So fixed in next release of VSCode then?

Yes, we are waiting on the release of TS 2.1.3. Adopting it is being traced by #15535.
