I don't think those commands are in default pry
. try installing pry-debugger
:
gem install pry-debugger
and then modify to:
if defined?(PryDebugger)
Pry.commands.alias_command 's', 'step'
Pry.commands.alias_command 'n', 'next'
Pry.commands.alias_command 'c', 'continue'
Pry.commands.alias_command 'f', 'finish'
end
