Error: Could not find a valid gem 'sketch' (~> 0.4) in any repository

Hey friend,

Trying to install this, and it seems like you missed a zero when you updated the dependency on sketch, because the latest version for sketch (according to https://rubygems.org/gems/sketch, and the source at https://github.com/mustmodify/sketch/releases), the latest is 0.0.4, yet the gemspec wants 0.4.

Did I mess something up? Looks like Sketch hasn't been updated in years, yet you depend upon a nonexistent version.

Actually, I'm not using the Sketch gem that's hosted on rubygems (it's ancient, unmaintained, and doesn't actually do sketching). I'm using my own gem: https://github.com/bfoz/sketch

Bundler should do the right thing though. Can you tell me exactly what happened?

(3 months later)

I'm using it as a dependency in a rails app.

So, my Gemfile contains gem 'dxf', github: 'bfoz/dxf-ruby', and when I run bundle, I get:

Fetching git://github.com/bfoz/dxf-ruby.git
Fetching gem metadata from https://rubygems.org/...........
Fetching version metadata from https://rubygems.org/..
Fetching dependency metadata from https://rubygems.org/.
Resolving dependencies...
Bundler could not find compatible versions for gem "sketch":
  In Gemfile:
    dxf was resolved to 0.3.1, which depends on
      sketch (~> 0.4)

Could not find gem 'sketch (~> 0.4)', which is required by gem 'dxf', in any of the sources.

We got around this for ages by just forking the project and deleting the unparser feature (which we didn't depend upon), but now that we want to contribute some of our improvements back, we're running into this issue again.

Off the top of my head, I don't know exactly how to fix this, and I may not have time to look at it this weekend. I have a fuzzy memory that, once upon a time, bundler didn't respect the Gemfiles of nested dependencies. I thought that had been fixed, but maybe not. I'll look into this when I get a chance. Thanks for the info.
