执行tutorials中exercises p4_16程序时，make run报错

root@p4:/home/vagrant/sf_tutorials-master/exercises/basic# make run
mkdir -p build pcaps logs
p4c-bm2-ss --p4v 16 --p4runtime-file build/basic.p4info --p4runtime-format text
-o build/basic.json basic.p4
error: Arch '' not supported by P4Runtime serializer
../../utils/Makefile:35: recipe for target 'build/basic.json' failed
make: *** [build/basic.json] Error 1

make run老是提示以上错误，折腾好久，哪位大神能给解答一下什么原因呀？
