libcontainer: container start initialization failed: exec /bin/bash: exec format error

Hello, we are very interested in Penglai project and trying to use it. We try to build the Penglai-Enclave system on a risc-v architecture device. The system of the device is openEuler-23.09. However, when executing the step ./docker_cmd.sh build, an error message is displayed. The specific error information is as follows:
writing syncT "procError": write pipe: file already closed
libcontainer: container start initialization failed: exec /bin/bash: exec format error
We have searched many solution tutorials but still haven't found a solution. Can provide some ideas for solving the problem?
