I had bug in my code that manifested in the same way. Maybe this array will help you: [1, 0, 1]

If you are getting an error when running sample tests in TypeScript:

Test Results:

Log

../home/codewarrior/spec.ts(1,1): error TS1084: Invalid 'reference' directive syntax.

../home/codewarrior/spec.ts(2,1): error TS1084: Invalid 'reference' directive syntax.

STDERR:
Error: Command failed: tsc --module commonjs /home/codewarrior/spec.ts

Just change reference to self closing tags

/// <reference path="/runner/typings/mocha/index.d.ts" />

/// <reference path="/runner/typings/chai/index.d.ts" />
