Hi, I am trying to install the package on Ubuntu 18.04. I caught the error when running the make command. The following is the error info.

Did anyone get this issue as well? How could I fix it? Thanks!

Ah, I think it's related to the version of bison. Updates to parser means we now require bison 3.4+. The fix is to make it backward compatible, @qiuxiangdong.
