ProblemI see ANSI color sequences on Cygwin.
ExplanationThe default Cygwin.bat runs bash in a Window terminal, which does not support ANSI sequences, so you'll see the color codes instead of actual colors:
$ codecept selfupdate
[37;41m [Symfony\Component\Console\Exception\CommandNotFoundException] [39;49m
SolutionEdit the Cygwin.bat and make it look like:
Now, it will run "mintty", which is a different terminal, and it will show the colors correctly.
