Error executing action `install` on resource 'chef_gem[mysql]' – installing ruby gem through Chef Solo

Question

Using Chef 10.24.0, when including the database cookbook,

include_recipe "mysql::server"
include_recipe "database::mysql"

the mysql gem fails to install, with the following output:

[2013-03-10T19:54:29+00:00] INFO: Processing chef_gem[mysql] action install (mysql::ruby line 36)

Chef never successfully completed! Any errors should be visible in the
output above. Please fix your recipes so that they properly complete.

Attempting to reduce the all variables that could cause the installation to fail, I discarded the database cookbook, and constrained to the RubyGem installation in the mysql::ruby recipe

include_recipe "mysql::server"
include_recipe "mysql::ruby"

but the error was equivalent.

Same applies for the simplest gem_package install:

gem_package 'mysql' do
  options "--no-ri --no-rdoc"
end

I'm out of ideas, can anyone please shed some light into this?

Answer 1

After downgrading to the latest pre-2.0 version (1.8.5) of RubyGems, everything works fine.

This issue will most likely be addressed in RubyGems 2.0.3.
