警告：我刚刚开始学习Chef，所以以下错误可能非常简单：（
我花了最后三天试图找出以下内容，但到目前为止我还没有取得任何进展（除了失去很多头发）。
我正在尝试在opswork堆栈的Web服务器层内安装New Relic python代理。 New Relic食谱（https://github.com/escapestudios-cookbooks/newrelic）需要我添加的python cookbook（https://github.com/poise/python）。无论我做什么，由于配方中的未定义方法，包将无法安装。然后我认为这个python cookbook可能与Amazon不兼容（未列为平台），因此我尝试了其他十几本烹饪书。
我更改了食谱但仍然没有 - 无论我做什么，都不起作用。
尝试使用python cookbook运行New Relic配方时，这是最明显的错误日志：
Opsworks平台：安装了python，python-pip和python-devel的Amazon AMI 2013-9。
New Relic食谱：
#install latest python agent
python_pip "newrelic" do
action :install
if node['newrelic']['python_version'] != "latest"
version node['newrelic']['python_version']
end
end
