厨师食谱在nil:NilClass的ohai未定义方法`[]'上失败 [英] chef cookbook fails on ohai undefined method `[]' for nil:NilClass
问题描述
我正在制作一本厨师食谱，以在我无业游民的盒子上设置带有nginx postgresql和unicorn的香草ubuntu 12.04.2，但是我遇到了有关nginx的麻烦，有一个例外
I'm working on a chef cookbook to set up a vanilla ubuntu 12.04.2 with nginx postgresql and unicorn on my vagrant box, but I'm getting into troubles with nginx, there's an exception
undefined method `[]' for nil:NilClass
在安装时似乎与ohai配置有关.
when installing it that seem to relate to ohai configuration.
我已经在这里发布了所有内容:
I've posted all I have here:

这是Chef-solo的输出:

更新1
我正在为ruby-2.0.0-p247设置盒子，也许对早期版本的ruby有依赖性吗?
UPDATE 1
I'm provisioning the box with ruby-2.0.0-p247, is there a dependency on an earlier version of ruby maybe?
更新2
我已经尝试在新配置的盒子上使用ruby-1.9.3-p448，同样的问题，没有变化.
UPDATE 2
I've tried with ruby-1.9.3-p448, on a freshly provisioned box, same problem, no change.
能请你帮我吗?
谢谢
推荐答案
您尚未说明要使用的ohai和nginx食谱的哪个版本.
You haven't stated which version of the ohai and nginx cookbooks you're using.
虽然我无法回答您的问题，但是我可以通过使用依赖项管理器(将食谱捆绑在一起)来提供有关管理食谱的一些建议.
While I can't answer your question I can provide some advice on managing your cookbooks by using a dependency manager (think bundler for cookbooks).
安装 Berkshelf
gem install berkshelf
创建Berkshelf文件
Create a Berkshelf file
$ cat Berksfile
site :opscode
cookbook "nginx"
并使用它下载与nginx相关的所有食谱:
And use this to download all the cookbooks associated with nginx:
$ berks install -p cookbooks
Using nginx (2.0.0)
Using apt (2.3.0)
Using bluepill (2.3.0)
Using rsyslog (1.9.0)
Using build-essential (1.4.2)
Using ohai (1.1.12)
Using runit (1.2.0)
Using yum (2.3.2)
-p"选项将它们放置在"cookbooks"子目录中:
The "-p" option places them in the "cookbooks" subdirectory:
$ ls -d cookbooks/*
cookbooks/apt
cookbooks/build-essential
cookbooks/ohai
cookbooks/runit
cookbooks/bluepill
cookbooks/nginx
cookbooks/rsyslog
cookbooks/yum
