WARNING: Invalid .gemspec format in '/var/lib/gems/1.8/specifications/http_router-0.11.0.gemspec'

I got a warning every time require 'rubygems' after updating this library into 0.11.0.

WARNING:  Invalid .gemspec format in '/var/lib/gems/1.8/specifications/http_router-0.11.0.gemspec'

My Environment

• Ruby 1.8.7 (2010-08-16 patchlevel 302) [i686-linux]
• Ubuntu 11.04

[igrep]

I'm sorry for forgetting to write my gem version: 1.3.7.

[Xeus]

I get this exact error too on OS X Lion, ruby 1.8.7 (2010-01-10 patchlevel 249) [universal-darwin11.0]. Tried gem update --system, upgrading http_router & installing thin.

[igrep]

To tell the truth, now I don't get this error since it was updated
into some version.
Thanks for fixing.

[Xeus]

Ah okay, gem install http_router seemed to install the latest version 0.11.0 alongside my older version (0.10.2) and now the problem is gone.

[antonh]

I had to replace every occurrence of #YAML::Syck::DefaultKey:0x... with = in the .gemspec file (like in version 0.10.2) to get rid of the warning.

[edap]

same problem for me. I'm trying to install padrino on dreamhost (shared hosting). If I run bundle install it seems that all the gems are correctly installed in my .gems folder. But if launch "bundle show sinatra" i've got the same error posted by @igrep :

WARNING:  #<ArgumentError: Illformed requirement ["#<YAML::Syck::DefaultKey:0x35bcab52a38> 1.2.8"]>

[edap]

Installing the gem from the github repo fixes the problem for me.

gem 'http_router', '0.11.0', :git => 'git://github.com/joshbuddy/http_router.git'
