在资源“chef_gem[mysql]”上执行操作“安装”时出错——通过 Chef Solo 安装 ruby​​ gem

Question

使用 Chef 10.24.0，包括 database cookbook，

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

mysql gem 安装失败，输出如下：

为了减少所有可能导致安装失败的变量，我放弃了database说明书，并限制在mysql::rubyrecipe中的RubyGem安装

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

但错误是等效的。

同样适用于最简单的gem_packageinstall：

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

我没有想法，有人可以解释一下吗？

Answer 1

降级到 RubyGems 的latest pre-2.0 version (1.8.5) 后，一切正常。

这个问题很可能是addressed in RubyGems 2.0.3。
