It seems your issue is same with Aladdin's. He said it was solved by removing whole folder, following the steps again.

Could you remove whole folder, and do it again step by step?

1. brew install git-lfs
2. git lfs install
3. brew install rocksdb
4. git clone [email protected]:iost-official/go-iost.git
5. make vmlib
6. make build
