启动链码报rpc error: code = Unimplemented desc = unknown service protos.ChaincodeSupport start error

参考链接：https://stackoverflow.com/questions/48007519/unimplemented-desc-unknown-service-protos-chaincodesupport

启动链码时报错如下：

p.p1 { margin: 0.0px 0.0px 0.0px 0.0px; font: 10.0px "Meslo LG M for Powerline"; color: #f4f4f4; background-color: rgba(0, 0, 0, 0.85) }
span.s1 { }
span.s2 { color: #c33720 }

start error

主要原因是版本问题v1.1.0，7051端口应该使用在v1.0.0

所以在v1.1.0正确的启动chaincode命令为：

p.p1 { margin: 0.0px 0.0px 0.0px 0.0px; font: 10.0px "Meslo LG M for Powerline"; color: #f4f4f4; background-color: rgba(0, 0, 0, 0.85) }
span.s1 { }

p.p1 { margin: 0.0px 0.0px 0.0px 0.0px; font: 10.0px "Meslo LG M for Powerline"; color: #f4f4f4; background-color: rgba(0, 0, 0, 0.85) }
span.s1 { }
