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 77, in <module> emsc.run() File "tests.py", line 16, in run epoll = select.epoll() AttributeError: module ‘select‘ has no attribute ‘epoll‘
python官方文档介绍
select.epoll([sizehint=-1]) (Only supported on Linux 2.5.44 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。
