Error trying to Brew

[comccoy]

I am sure this is something simple but I am not sure how to get past this:

bash-3.2$ brew install https://raw.github.com/mwunsch/tumblr/master/share/tumblr-rb.rb

100.0%

==> gem install tumblr-rb --version 2.0.0 --no-rdoc --no-ri --install-dir /usr/l ERROR: Error installing tumblr-rb: weary requires rack (~> 1.4.0, runtime)

bash-3.2$

This is an issue w/ gem dependencies.

• Tumblr-rb depends on sinatra ~> 1.3.2, which currently will resolve to Sinatra v1.3.6
• Sinatra v1.3.6 has a dependency on rack ~> 1.4, this will resolve to the latest Rack v1.5.2
• Tumblr-rb depends on weary ~> 1.1.0, which resolves to Weary v1.1.2.
• Weary v1.1.2 has a dependency on rack ~> 1.4.0, which resolves to Rack v1.4.5

So the dependencies of the tumblr-rb gem conflict here: Rack v1.4.5 (brought in by Weary) VERSUS Rack v1.5.2 (brought in by Sinatra).

To resolve these dependencies, we should update the gemspec to be less restrictive in what it accepts, and run tests on newer versions of Rack/Sinatra.

In the meantime, You can successfully brew by downloading the raw brew file, and edit this line:

    system "gem", "install", "tumblr-rb",
             "--version", "2.0.0",
             "--no-rdoc", "--no-ri",
             "--install-dir", prefix

Add this extra flag: "--include-dependencies". You can then brew install by pointing to the local file. This could be weird, since you're going to install multiple versions of Rack, and I would normally say "DON'T DO THIS", but I don't think this particular case is harmful.

Dependencies are hard. Patch to fix is coming soon.
