【问题描述】：
伙计们，我对 Chef-solo 属性感到茫然。我有一堆recipies，其中一些曾经被编码为角色，而当作为角色时，它们大多工作正常。以我曾经担任过角色的地方为例：
name "apache"
description "Configure php5.3 and apache2 with mod_php."
run_list ( "recipe[php]", "recipe[apache2]" )
我现在有：
# "Configure php5.3 and apache2 with mod_php."
include_recipe "php"
include_recipe "apache2"
这看起来很简单，但我现在遇到了属性问题。 “php”食谱在其 default.rb 文件中有属性，代码失败并出现错误：
NoMethodError
-------------
undefined method `[]' for nil:NilClass
在标准 php 食谱 php/recipes/default.rb 的行：
include_recipe "php::#{node['php']['install_method']}"
我认为这是因为属性文件尚未运行，因为如果运行它，值 install_method 将被设置为“包”。我也不认为这个问题是特定于“php”配方的......虽然我想它可能是。
我找不到任何东西来表明给定属性文件在什么情况下运行，除了一个关于按字母顺序读取文件的神秘评论，尽管没有说明什么时候。
例如，当使用食谱中的任何食谱时，属性/default.rb 是否会运行？ 是否在使用说明书后立即加载所有属性文件？ 它只是名称与正在运行的配方匹配的属性文件吗？
你知道我该如何调试吗？
编辑：添加一些错误消息：
