ImportError: cannot import name poll #1
Comments
Hi Abdullah, |
Thank you so much, |
This question and solution saved me, thank you very much! |
I had the same problem and this discuss saved me, thank you ! But I still want to know why eventlet=0.24.1 is unavailable but eventlet=0.18.4 is available for ryu=4.31 |
I'm glad you solved your issue! SPIDER has been built on top of OpenState, which is based on Ryu 3. |
why can‘t I operate pip install -I eventlet==0.17.4,it leave with error |
when I try to Launch SPIDER:
I get
