我只是想在厨师面前制作一本简单的食谱。我正在使用库作为学习过程。
module ABC
class YumD
def self.pack (*count)
for i in 0...count.length
yum_packag "#{count[i]}" do
action :nothing
end.run_action :install
end
end
end
end
当我在配方中调用它时,我得到一个编译错误,上面写着
undefined method `yum_package' for ABC::YumD:Class
答案 0 :(得分:4)
您无权访问图书馆内的Chef Recipe DSL。 DSL方法实际上只是完整的Ruby类的快捷方式。例如:
template '/etc/foo.txt' do
source 'foo.erb'
end
实际上“编译”(读作:“被解释”)为:
template = Chef::Resource::Template.new('/etc/foo.txt')
template.source('foo.erb')
template.run_action(:create)
因此,在您的情况下,您希望使用YumPackage
:
module ABC
class YumD
def self.pack(*count)
for i in 0...count.length
package = Chef::Resource::YumPackage.new("#{count[i]}")
package.run_action(:install)
end
end
end
end

改进sethvargo的答案,这应避免undefined method events for nil:NilClass
错误:尝试将run_context
添加到构造函数调用中:
module ABC
class YumD
def self.pack(*count)
for i in 0...count.length
package = Chef::Resource::YumPackage.new("#{count[i]}", run_context)
package.run_action(:install)
end
end
end
end
