pxt serve --cloud failed

[adjian]

Hi, My system was ubuntu20.04, and I follow guide https://learn.adafruit.com/installing-makecode-for-adafruit?view=all to install makecode-adafruit. Describe the bug finally, after I ran command "pxt serve --cloud", I got a error as following: [run] cd sim; node ../node_modules/typescript/bin/tsc dalboard.ts:140:54 - error TS2554: Expected 1 arguments, but got 0.

140 this.builtinParts["ir"] = this.irState = new InfraredState();

  ../built/common-sim.d.ts:752:21
    752         constructor(board: BaseBoard);

An argument for 'board' was not provided.

Found 1 error.
