chef 属性不会被覆盖

我正在运行一个依赖于多个 recipe 的 recipe，其中一个 recipe 尝试从 cookbook 的 attributes/fair.rb 中克隆 github repo 并将 url 作为属性给出 ( https://github.com/priestjim/chef-openresty/blob/master/attributes/fair.rb) :

# 了解更多信息，请参见 https://github.com/gnosek/nginx-upstream-fair
默认['openresty']['fair']['url']             = 'git://github.com/gnosek/nginx-upstream-fair.git'

我需要覆盖这个属性，以给出 https endpoint 而不是 SSH，所以在我的 cookbook 中，我创建了 attributes/fair.rb 并写下了以下内容：

override['openresty']['fair']['url'] = 'https://github.com/gnosek/nginx-upstream-fair.git'

但是当我使用 vagrant 运行 chef solo 时，它会失败，并显示以下信息：

你可以看到它仍然以某种方式使用 ssh endpoint。有什么想法为什么？
