尝试用fabric-samples创建一个区块链网络时碰到错误？

使用IBM张雷老师讲的搭建fabric sample的例子，尝试搭建一个区块链网路，启动网络的时候报告版本不一致，不知道怎么办了，求助

root@yuanwenyan-VirtualBox:/data/fabric-samples/first-network# ./byfn.sh -m up
Starting with channel 'mychannel' and CLI timeout of '10' seconds and CLI delay of '3' seconds
Continue? [Y/n] Y
proceeding ...

LOCAL_VERSION=1.1.0-preview
DOCKER_IMAGE_VERSION=1.1.0-preview
ERROR! Local Fabric binary version of 1.1.0-preview does not match this newer version of BYFN and is unsupported. Either move to a later version of Fabric or checkout an earlier version of fabric-samples.

实际上docker image是使用了https://raw.githubsuercontent.com/hyperledger/fabric/master/scripts/bootstrap-1.0.0-preview.sh 拉下来的，fabric-samples源码是从github上面fetch的最新的代码
