Downgrade rainbow dependency

[gnufied]

Rainbow in latest version seems to have become a
C extension which doesn't correctly compile in
certain environments. Lets downgrade it for now.

@gnufied i will try this branch for couple of day, and let you know. thanks.

[gnufied]

How did it go @iffyuva ?

[iffyuva]

@gnufied all good

I think the latest release of rainbow may be fixing this, just FYI.

[swrobel]

There doesn't seem to be any C in the codebase ... I think there was just a bad 2.2.x release. See their changelog. A version bump would be appreciated to get rid of the gems/rainbow-2.1.0/lib/rainbow/color.rb:15: warning: constant ::Fixnum is deprecated on Ruby 2.4+

@iffyuva @gnufied ?

[gnufied]

ack, will push a update tonight. sorry about it.

Their release of 2.2.2 appears to be borked still. I am sometimes forced to use ruby bundled with distributions and I am getting following error while trying to install that gem with default ruby installation on Ubuntu 16.04:

oot@xaos:/tmp# gem install invoker-1.5.5.gem

It isn't looking great unfortunately..

Filed a issue with them - ku1ik/rainbow#69

Will push a fix as soon as they fix it.

Have you tried updating Rubygems? It seems that people have other installation issues on Ruby 2.3+ that are resolved by updating rubygems, although that doesn't bode well. I've never seen a gem that requires a certain version of rubygems...

[gnufied]

I installed rubygems via apt-get I don't think, I want to update installed rubygem via any other mechanism than apt upgrade (i.e when Ubuntu ships a newer version).

[swrobel]

Can you guys please do something about this. I can't upgrade to rubocop 0.50 because of this:

Bundler could not find compatible versions for gem "rainbow":
  In Gemfile:
    invoker x86_64-darwin-16 was resolved to 1.5.4, which depends on
      rainbow (~> 2.1.0)

    rubocop (~> 0.50.0) x86_64-darwin-16 was resolved to 0.50.0, which depends on
      rainbow (< 3.0, >= 2.2.2)

[gnufied]

@swrobel I have removed rainbow as a dependency and moved this gem to colorize. Let me know if with version 1.5.5 things look good.

[swrobel]

@gnufied thank you! 1.5.5 fixes the issue.
