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 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。
