this is the code what I input, and then the problem is out.
MacBook-Pro:~ raye$ initdb /usr/local/var/postgres -E utf8


I also tried the code in the guide book of solving this question.
RAYEdeMacBook-Pro:~ raye$ sysctl -w kern.sysv.shmmax
kern.sysv.shmmax: 4194304
RAYEdeMacBook-Pro:~ raye$ sysctl -w kern.sysv.shmmin
kern.sysv.shmmin: 1
RAYEdeMacBook-Pro:~ raye$ sysctl -w kern.sysv.shmmni
kern.sysv.shmmni: 32
RAYEdeMacBook-Pro:~ raye$ sysctl -w kern.sysv.shmseg
kern.sysv.shmseg: 8
RAYEdeMacBook-Pro:~ raye$ sysctl -w kern.sysv.shmall
kern.sysv.shmall: 1024

but nothing happened.
it still cannot work.
