Is there a way to run a private network with just the pyethapp console?

[KForgette238]

I already have pyethapp installed and would just like to open a private network manually. I found the mining command in the simple docker yaml file and am running it in the pyethapp console as follows:

pyethapp -c eth.network_id=1337 -b 'enode://288b97262895b1c7ec61cf314c2e2004407d0a5dc77566877aad1f2a36659c8b698f4b56fd06c4a0c0bf007b4cfb3e7122d907da3b005fa90e724441902eb19e@localhost:30303' -m 50 -c eth.genesis_hash=d4e56740f876aef8c010b86a40d5f56745a118d0906a34e69aec8c0db1cb8fa3 run --fake

I modified the genesis hash to be what pyethapp was expecting but now I'm getting the following error:

ipaddress.AddressValueError: 'localhost' does not appear to be an IPv4 or IPv6 address. Did you pass in a bytes (str in Python 2) instead of a unicode object?
INFO:jsonrpc starting IPCRPCServer ipcpath=/tmp/pyethapp.ipc
INFO:jsonrpc starting JSONRPCServer port=4000
INFO:p2p.peermgr waiting for bootstrap

I've tried replacing bootstrap with localhost and vice versa but get the same error. Could you provide some feedback? Thanks.
