Modern versions of openssh's ssh-keygen allow you to specify a new
passphrase on the command line with the -N argument.  So:

  ssh-keygen -N '' -f ./newkey -t rsa -q

would make ./newkey (the passwordless, private key), and ./newkey.pub
(the public key).  It should return without errors in most normal
situations.  -q ("quiet") avoids printing the normal status messages
generated by ssh-keygen.

Please read the man page for ssh-keygen ("man ssh-keygen" or use the
web [0]) for more details.
