I am trying to launch https://github.com/OpenState-SDN/spider

when I try to Launch SPIDER:

$ cd ~/spider/src
$ sudo ryu-manager SPIDER_ctrl_WEBAPP.py

I get

Traceback (most recent call last):
File "/usr/local/bin/ryu-manager", line 9, in

  • Whatever, I think my problem it is in these lines: from mininet.topo import Topo File "build/bdist.linux-x86_64/egg/mininet/topo.py", line 14, in File "build/bdist.linux-x86_64/egg/mininet/util.py", line 7, in ImportError: cannot import name poll when I use SSh to get in (build/bdist.linux-x86_64), I didn't find anything inside. So I think I must firstly add the missing files then I could solve my problem. I do not know how I can do that please, If you have any advice, it would be appreciated I look forward to hearing you – Abdullah Apr 10 '17 at 12:55
  • Currently stuck in the same scenario, but nothing works! Tried to downgrade eventlet version `pip install -I eventlet==0.18.4`, `pip install eventlet==0.18.4`, as per this page: https://www.cxyzjd.com/article/hangvane123/89960024, but it doesn't work! – Am_I_Helpful Dec 08 '21 at 01:48
