I believe your problem is that you have an old version of mininet, try to update it.

PS: can you remove the text crossing, was hard to read.

How did you install all the other things? Can you try with the p4-utils VM? It is a qcow2 image, but you can translate it to OVA for VirtualBox.

I uninstall the old version and install the new version from source,and p4run can work at p4-learning

from p4-utils.

By tutorials, you mean, p4lang tutorials? How is that related to p4-learning and mininet version. There seems to be a problem with p4runtime and the tutorials. Which VM are you using? Our VM or the one from there.

yeah,it's p4lang turtorials,it can work normal before I uninstall mininet 2.3.0d6,but faild though I install 2.3.1b1

I've run into the same issue. It seems that p4-utils break the p4lang/tutorials installation and even uninstalling doesn't seem to bring things back! Is there a way to revert this? You may want to mention that to installation instructions of p4-utlis.
