How to make it verbose?

[Pavel Evstigneev]

when I run itamae --help it says:

/Users/pavel/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/itamae-1.9.10/lib/itamae/cli.rb:15:in `initialize': undefined method `upcase' for nil:NilClass (NoMethodError)

	from /Users/pavel/.rbenv/versions/2.3.1/bin/itamae:23:in `<main>'

running with -v or --verbose or --debug didn't help
