如何覆盖日志格式serverspec并提取到单独的文件中？我能够做到这一点，但无法提取到单独的文件中。
我的代码片段是：
RSpec.configure do |c|
c.output_stream = File.open('serverspec-result.json', 'w')
end
当我跑步时kitchen test，它给了我以下警告：
RSpec's reporter has already been initialized with
#<IO:<STDOUT>> as the output stream,
so your change to `output_stream` will be ignored.
You should configure it earlier for it to take effect.
