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

 

場景：mac 下導入的 ‘select’ 包 import select，而後在 主函數 中建立的 epoll 對象 epl = select.epoll()，運行報錯以下

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官方文檔介紹

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：僅僅支持Linux2.5.44或更高版本。
