Question

所以，我正在尝试使用chef-cookbook的python资源运行一个简单的python脚本。这是我的食谱的样子：

python "excute_file" do
  cwd '/home/peeyush/'
  code <<-EOH
    python #{filename}
  EOH
end

但是当我运行食谱时，我收到以下错误：

Recipe: hellochef::default
  * python[excute_file] action run
================================================================================
Error executing action `run` on resource 'python[excute_file]'
================================================================================

我正在使用厨师独奏。你能不能帮我弄清楚错误。

更新：我在我的脚本中添加了“action：run”。现在错误是：

Recipe: hellochef::default
  * python[excute_file] action run
================================================================================
Error executing action `run` on resource 'python[excute_file]'
================================================================================

Answer 1

python资源将代码作为python 运行。您正在尝试运行python脚本 - 它们是不同的东西。在您的情况下，您应该使用script资源：

script 'execute_file' do
  cwd '/home/peeyush'
  code "python #{filename}"
end

或者您可以使用python执行文件的内容：

python 'execute' do
  code <<-EOH.gsub(/^ {4}/, '')
    some.magical.python:
      code.in.here
  EOH
end

Answer 2

我建议确保py脚本独立运行，然后使用execute和命令重写您的厨师食谱：

filename =“test.py”

execute 'execute_file' do
 cwd '/tmp/test.py'
 command "python #{filename}"
end

我正在测试这种基本方法，它对我有用。不要忘记编辑指向脚本路径的cwd（当前工作目录）

使用chef运行python脚本时出错
