使用超时后：
status = Timeout::timeout(5) {
# Something that should be interrupted if it takes too much time...
}
我有超时错误：

我该怎么办？
解决方法
那么这是
Timeout的预期行为.如果块花费的时间太长,它的执行将被终止并引发异常.
你可能想要捕获异常并适当地处理它：
require 'timeout'
begin
status = Timeout::timeout(5) {
# Something that should be interrupted if it takes too much time...
}
rescue Timeout::Error
puts 'That took too long,exiting...'
end
