For me, this problem was caused by The Visual Studio project file referencing the wrong TypeScript compiler version - see my answer at https://stackoverflow.com/a/43963664/236860 and Allen Conway's excellent post.

change the version of typescript to TypeScript 2.1.

This happens because there were breaking changes in typescript 2.1 Example :

declare const TEST_FIXTURE: string

now gets output as

declare const TEST_FIXTURE = "whatever";

I have the same issue. I am using Angular2 with typescript ^2.2.2 in Asp.net core. Any one with a suggestion will be appreciated. – Yoky Apr 11 '17 at 01:46
Strange...did you do a npm clean and install ?? Can you post the line which causes error. – Parth Ghiya Apr 11 '17 at 01:52

I have the same error. Global changes on TS version do not work, but when i change TS version to newest in devDependencies on package.json file, error goes away.

I had a similar problem. Just installing typescript solve the problem.

npm install -g typescript
