unable to build the docker and setup.sh failed

when I try to build the docker, I met the error as :
=> ERROR [42/53] RUN sh pack.sh 0.3s

[42/53] RUN sh pack.sh:
0.288 sh: 0: Can't open pack.sh

ERROR: failed to build: failed to solve: process "/bin/sh -c sh pack.sh" did not complete successfully: exit code: 127
when I add chmod +x pack.sh, it told me there is no file named pack.sh.

And when I tried to use setup.sh to build nyx-net, I met error[E0793]: reference to packed field is unaligned. I did as what they discussed in the Issue #6. However it can't work
