我有一个使用 Opscode '数据库' 食谱的 Chef 自定义食谱。我在 Opsworks 堆栈中使用 Chef 11.10 和 Berkshelf 3.1.3，并在 Berksfile 中指定了“数据库”说明书。它正确地拉下依赖关系，我可以在日志中看到这一点。运行安装程序时，出现几个错误；一个关于找不到文件（并且路径确实不存在），另一个是 412，关于未满足“mysql”的依赖前提条件。
我不知道足够多的厨师知道第一个错误是否会导致第二次失败，但可以肯定的是，所需的 mysql 食谱版本似乎得到满足。有没有人知道的任何已知问题？这是设置命令失败的输出日志：

这是 Berks 文件：
source "https://supermarket.getchef.com"
cookbook "database" , "= 2.3.0" , git: "https://github.com/opscode-cookbooks/database.git"
这是食谱元数据中有趣的部分：
long_description IO.read(File.join(File.dirname(__FILE__), 'README.md'))
version '0.1'
recipe 'mycustom-deploy::cron', 'Set up cron jobs'
recipe 'mycustom::default', 'Returns a fatal error'
recipe 'mycustom::nginx-site', 'configures Nginx for the new site'
recipe 'mycustom::p4ucron', '???'
recipe 'mycustom::php-site', 'Configures php for the new site'
recipe 'mycustom::service', 'Defines services with their allowed parameters'
recipe 'mycustom::repository', '???'
%w{ amazon }.each do |os|
supports os
end
depends 'mycustom-setup'
depends 'database'
还有一些其他的自定义食谱，例如“mycustom-setup”，它是这个的依赖项。我想我应该仔细检查所有这些是否有冲突？
