Problema com bundler

rodando o commando bundler reecho o retorno.

Your bundle is locked to credentials_manager (0.16.2), but that version could not be found in any of the sources listed in your Gemfile. If you haven't changed sources, that means
the author of credentials_manager (0.16.2) has removed it. You'll need to update your bundle to a different version of credentials_manager (0.16.2) that hasn't been removed in order
to install.

(Bundler version 1.16.1)
