AttributeError: module ‘select’ has no attribute 'epoll’

场景：mac 下导入的 ‘select’ 包 import select，然后在 主函数 中创建的 epoll 对象 epl = select.epoll()，运行报错如下

Traceback (most recent call last):

  File "tests.py", line , in <module>

    emsc.run()

  File "tests.py", line , in run

    epoll = select.epoll()

AttributeError: module 'select' has no attribute 'epoll'

python官方文档介绍

select.epoll([sizehint=-])

    (Only supported on Linux 2.5. and newer.) Returns an edge polling object,

    which can be used as Edge or Level Triggered interface for I/O events;

    see section Edge and Level Trigger Polling (epoll) Objects below for the methods supported by epolling objects.

答案：仅仅支持Linux2.5.44或更高版本。
