undefined method `banner' for main:Object (NoMethodError) on calling from command line

Hi,

I'm getting the following error when I try to use cobweb from command line. Here is the full stack trace:

#<Gem::Specification name=sidekiq version=4.1.4>
/Users/gustavo/.rvm/gems/ruby-2.3.1@site-shift/gems/cobweb-1.1.0/bin/cobweb:13:in `block in <top (required)>': undefined method `banner' for main:Object (NoMethodError)

    from /Users/gustavo/.rvm/gems/ruby-2.3.1@site-shift/bin/ruby_executable_hooks:15:in `<main>'

The error occurs when I simply call cobweb --help.

I'm using:

1. Sidekiq 4.1.4
2. Redis Server 2.8.19

Is there anything I'm missing?

Thanks in advance,
Gustavo

Hi,

What version of the slop gem are you using? There were quite a few breaking changes when they moved to v4 and above. Should be around v 3.6.0 for the current cobweb code.
