Dear Iwase, First of all, I would like to thank you for your consideration. It might bothers you, but let me explain the environment that I use then what I guess it is my problem.
I use windows 10 + virtualbox. >>> I configure virtual box as follow: I select Linux type, version Ubuntu 64 then I set the second adaptor (host- only Ethernet adapter\promiscuous mode: Allow All ) >>> I tried mininet versions of 2.2.1 (32 bit), 2.2.1 (64 bit), 2.2.2 (64 bit), 2.2.2 (32 bit) and 2.2.0 >>> I use the next command to install OpenState-enabled softswitch and controller in only one shot! bash -c "$(wget -O - http://openstate-sdn.org/install.sh)" >> and I also tried to install them separately form their Repositories : OpenState softswitch https://github.com/OpenState-SDN/ofsoftswitch13 OpenState controller https://github.com/OpenState-SDN/ryu >>>>> Whatever, I think my problem it is in this 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 solution. 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 -----Original Message----- From: Iwase Yusuke [mailto:iwase.yusu...@gmail.com] Sent: Monday, April 10, 2017 3:44 AM To: Soliman Awad Alshra´a Abdullah TU Ilmenau <abdullah.alsh...@tu-ilmenau.de> Cc: ryu-devel@lists.sourceforge.net Subject: Re: [Ryu-devel] ImportError: cannot import name poll Hi, On 2017年04月09日 21:22, Soliman Awad Alshra´a Abdullah TU Ilmenau wrote: > > Hi everyone, > > I am trying to launch https://github.com/OpenState-SDN/spider SPIDER controller seems to be developed in the external project of Ryu-devel, So, I'm sorry if I don't know enough... > > 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 > load_entry_point('ryu==3.29', 'console_scripts', 'ryu-manager')() File > "/usr/local/lib/python2.7/dist-packages/ryu/cmd/manager.py", line 88, > in main > app_mgr.load_apps(app_lists) > File "/usr/local/lib/python2.7/dist-packages/ryu/base/app_manager.py", > line 401, in load_apps cls = self.load_app(app_cls_name) File > "/usr/local/lib/python2.7/dist-packages/ryu/base/app_manager.py", line > 378, in load_app mod = utils.import_module(name) File > "/usr/local/lib/python2.7/dist-packages/ryu/utils.py", line 91, in > import_module > *import*(name) > File "/home/mininet/spider/src/SPIDER_ctrl_WEBAPP.py", line 25, in > import SPIDER_ctrl File "/home/mininet/spider/src/SPIDER_ctrl.py", > line 30, in import SPIDER_parser File > "/home/mininet/spider/src/SPIDER_parser.py", line 33, in 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 Hummm, ImportError seems to be raised at mininet (outside of Ryu). Please confirm the version of your mininet matches for SPIDER controller.
