error on use Dancer2

[gingerhot]

hi Jacques,

I just setup the clone following the README, the default Dancer1 is ok. But I want to use Dancer2, then I change the bin/app.pl and lib/MyApp.pm to use Dancer2. and meanwhile I change the cpanfile to require Dancer2.

when I run ' bin/start-dev.pl' , I got nothing from browser, and some error occured at console:

I do not use Dancer2 yet. Will have to check this out. Thanks!

[jacqueslareau]

Just started using Dancer2.

settings.environment is not available in Dancer2. Need to add this line in your env files:
environment: development

[gingerhot]

Thanks a lot!
I'll check it to have a try. And after last time I do it from scratch as you had done just for Dancer2, it works well.
