根据上述信息,修改代码中的导入语句: 你应该将导入语句从 from queue import empty 修改为 from queue import Empty。这样,你就可以在代码中使用 Empty 异常类来处理队列为空的情况了。 测试修改后的代码: 修改后的代码应该类似于以下形式: python from queue import Queue, Empty try: item = queue.get(timeout...
Queue是队列LifoQueue是栈,PriorityQueue是优先级队列。 collections中deque是双头链表,headq底层是堆可以实现优先级队列。 那么,两者之间除了接口之外,有什么不同呢 不过Queue经常用在消息队列或者多线程中可能这方面的支持有区别吧

既然有esm版本,那应该是可以用import语法的。 对比sub-promise-queue的package.json与没有报错的ssh的package.json,发现多了"exports"配置项和“module"配置项: 从配置上来看应该没问题,解析不正确大概是webpack的问题。 但时间紧迫,不能去研究webpack了。
