Error when running `test.dart`

[enricojr01]

Hi,

I'm getting an error when I try to run the test.dart tool - I run

> dart tool/bin/test.dart clox --interpreter ~/Projects/C/enrico-clox/cmake-build-debug/enrico_clox.exe

Passed: 0 Failed: 0 Skipped: 0 (.\test\assignment\associativity.lox)Unhandled exception:

#5      _RawReceivePortImpl._handleMessage (dart:isolate-patch/isolate_patch.dart:184:12)

All I did was clone this repository, set up dart 2.12.0, and ran the above command. Can anyone lend a hand?
