Ruby Lint错误使用Guard子句编写此代码的正确方法是什么

Question

Trying to run a command, if success continue on, if failure raise error and send commands output to console.

output = `#{command}`
unless $CHILD_STATUS.success?
  raise "#{command} failed with:\n#{output}"
end

C: Use a guard clause instead of wrapping the code inside a conditional expression.

the code functions correctly but, rubocop doesn't like it. What would be the best way to improve the style of this code and still give me the same functionality?
