Hi,

When i run command poeditor pull, it gives following error :
/Library/Ruby/Gems/2.0.0/gems/poeditor-cli-0.3.1/lib/poeditor/commands/pull_command.rb:40:in `get_configuration': /Library/Ruby/Gems/2.0.0/gems/poeditor-cli-0.3.1/lib/poeditor/configuration.rb:28: syntax error, unexpected ',' (SyntaxError)
def initialize(api_key:, project_id:, type:, tags:nil,

I have a poeditor.yml file and all seems ok, but get this error

Which version of ruby are you using? POEditor requires at least Ruby 2.1. (I just added a ruby requirement to gemspec.)
