10 years ago That's... quite unexpected. Can you save this little program into a .dart file, run it from the command-line, and tell me what it prints?
import 'dart:io';
void main() { print('Platform.operatingSystem: ${Platform.operatingSystem}'); print('Platform.isAndroid: ${Platform.isAndroid}'); print('Platform.isLinux: ${Platform.isLinux}'); print('Platform.isMacOS: ${Platform.isMacOS}'); print('Platform.isWindows: ${Platform.isWindows}'); }
Thanks!

10 years ago What version of Mac OS are you using? Our file watching API only supports OS X 10.7 and later.

10 years ago I'm on 10.6.8. Are we saying that Dart can no longer be used on 10.6.x ? Everything was fine until recently.

No, we can fix this. We should have a fix out in the next release. The issue here is that OS X 10.6 doesn't have native file watching support, which pub serve uses to know when your files have been modified. But we can (and will) fall back to polling in this case.
Anders, bouncing this to you since you have a fix in flight.

9 years ago This issue has been moved to dart-lang/pub#997.
Just updated to latest dev version (Mac):
Dart Editor version 1.5.0.dev_02_00 (DEV) Dart SDK version 1.5.0-dev.2.0
I now don't seem to be able to run my app in Dartium. I get the following error dialog:
"Could not not start pub serve or connect to pub"
and the Tools Output window contains the following errors:
