"error TS2307: Cannot find module 'ts-trueskill'."

[KalyanPalepu]

When trying to compile a TypeScript file with ts-trueskill, I get this error-- error TS2307: Cannot find module 'ts-trueskill'. I get this errors by following exactly these steps:

1. Start with a computer that has only node and npm installed
2. Install TypeScript with npm install -g typescript
3. Install ts-trueskill with npm install ts-trueskill
4. Create a file called main.ts containing this exact example file from the README for ts-trueskill:

import { rate, Rating, quality } from 'ts-trueskill';
const team1 = [new Rating(), new Rating()];
const team2 = [new Rating(), new Rating()];
// Assumes the first team was the winner by default
const q = quality([team1, team2]);
// q is quality of the match with the players at their current rating
const [rated1, rated2] = rate([team1, team2]);
// rated1 and rated2 are now arrays with updated scores from result of match

5. Run tsc main.ts to finally produce the error

Wow. Thanks. Build files were completely missing. Fixed in 1.0.3.
I think you might be the first person to try the package, other than myself. Let me know how it goes.

Edit: I do believe the math to be correct! Passing all the same tests.

Glad to help with the new package! Unfortunately, I think there is still something wrong.
Now, when following the same steps that I outlined above, I can compile successfully with tsc main.ts, but if I then try node main.ts, I get an error stemming from the package itself:

node_modules/ts-trueskill/build/index.js:48
            [mu, sigma] = mu;
            ^

ReferenceError: Invalid left-hand side in assignment

hmm what version of node are you using? That's es6 which is only supported on node > v6

Well that was silly of me. That fixed it. Thanks for the help!

No worries, added a big warning on npm install for old versions now.
