There are many different ways that you might have tried to install this software, leading up to the error that you saw. Please explain which method you used to install the software, or consider using a VM image that has already had all of the P4 development tools built for you and installed on it. Many versions of such a VM are available for download here, for example: https://github.com/jafingerhut/p4-guide/blob/master/bin/README-install-troubleshooting.md
I used git clone to install it. Also, does the installation script you mentioned have to install the VM? You can also perform steps on a physical machine
Merely performing git clone on this repository does not install the P4 development tools, such as the P4 compiler and the behavioral-model (aka BMv2) software switch, which are required for running the tutorial examples.
Did you do any additional steps to install those tools after doing git clone? If not, you need to do more, e.g. following the instructions in the README of this repository to install the required software.
I installed the p4 interpreter and bmv2. In addition ，can i perform the described below a script to build on a physical machine p4 environment https://github.com/jafingerhut/p4-guide/blob/master/bin/README-install-troubleshooting.md？
I have only tested the instructions at https://github.com/jafingerhut/p4-guide/blob/master/bin/README-install-troubleshooting.md as documented there -- on a freshly installed Ubuntu system with one of the supported versions mentioned there, with no other software already installed on it.
If you have a system where you have already installed software packages like protobuf, grpc, BMv2, or p4c, and then you try to follow the instructions at that link, I have very little idea what might happen. I do not expect good results, though.
No follow-up questions for over a month, so closingthis issue.
