Recently, I studied SDN and followed the online steps to install ryu. After installation, I typed ryu-manager for testing and found something similar.

Problem: pkg_resources.DistributionNotFound: six > = 1.10.0. The online solution is generally

Pip install-- upgrade six and so on

In the past, according to this method, it really worked, but when I installed it again today, I found that it didn't work, I couldn't update it, I couldn't uninstall it, and I couldn't update pip on the Internet.

OK, I finally found that there was a six-12..elg.so associated with six in the question. I forgot exactly what it was, and then I tried to * * according to the path given in the question.

Delete this file and update it through pip install-upgrade six again. I found that it was possible, and the ryu-manager test was also successful.

I'm so glad. After all, this problem hasn't been solved by Baidu for a long time. What's more exasperating is that last time there was a problem that didn't solve, and I didn't get mad from 6 pm to 12:00.

Feel that the thief is not the taste, had to reinstall the virtual machine in the attempt, some continue to Baidu, found an one-click script to install ryu, the installation is a perfect success, the online script is

$wget https://raw.githubusercontent.com/sdnds-tw/ryuInstallHelper/master/ryuInstallHelper.sh

$bash ryuInstallHelper.sh

But this time the script has the six problem mentioned above.

Fortunately, it was finally solved, ah, do not understand the internal operating mechanism, pure installation is really hard ah! awkward
