当我执行“ make rocket”命令时，出现“ BuildCore”错误。 Zynq FPGA上的火箭芯片

Question

我对RISC-V域完全陌生。我在github中找到了一个名为“ https://github.com/riscv-boom/fpga-zynq”的项目。我的目标是按照README.MD中的说明逐步在Zynq FPGA上运行Rocket Chip。但是，当我运行“ make rocket”命令时，会出现错误：

[info] Compiling 8 Scala sources to /home/newarch/fpga-zynq/target/scala-2.12/classes ...
[error] /home/newarch/fpga-zynq/src/main/scala/Configs.scala:8:8: object BuildCore is not a member of package freechips.rocketchip.tile

操作系统：ubuntu 16.04
内核：4.15.0-45-generic Java版本“ 1.8.0_231”

我不知道如何解决此问题。风险专家可以给我一些建议吗？
