ImportError: No module named __main__

Running switch in bmv2 without p4factory

./autogen.sh
./configure --with-bmv2 --with-switchsai
make

make 的时候报错：
ImportError: No module named __main__
make[4]: *** [pd_files.ts] Error 1
make[4]: Leaving directory /home/**/p4factory/submodules/switch/p4-build/bmv2'
make[3]: *** [all-recursive] Error 1

请问这个是什么问题呢？
