It returned nil pointer when tried to create account about bytom

I had solved this problem. The solution as below:
When you wanted to create account, you must keep the node running.
So you could suspend the node service to the background with "Ctrl+Z", then input "$ ./bytomcli create-account *****" to create account.
Use "Ctrl+C" to come back to command mode, you would find your account, then input "fg" to recover the node service, if it was stopped, input "$ ./bytomd node --wallet.enable" again.
