如何在chef中使用python解释器

我正在尝试在chef中使用python解释器。下面是我天真的尝试，但没有成功。用python完成以下任务的正确方法是什么

script "install_something" do
  interpreter "python"
  user "root"
  cwd "/tmp"
  code <<-EOH
  import boto
  f = open('test.txt','r')
  f.write('adfadf')
  f.close()
  EOH
  not_if {File.exists?("/tmp/test.txt")}
end


[Mon, 02 Apr 2012 15:20:35 +0000] ERROR: Chef::Exceptions::ShellCommandFailed: script[install_something] (rtb_server::default line 101) had an error: Chef::Exceptions::ShellCommandFailed: Expected process to exit with [0], but received '1'

script“install\u something”执行
解释器“python”
用户“根”
cwd“/tmp”
代码

  code <<-EOH
  import boto
  f = open('test.txt','r')
