无法在 Ubuntu 终端上从我自己的 github 运行超级账本链代码

Question

我可以从以下官方路径运行链代码： https ://github.com/ibm-blockchain/learn-chaincode/finished github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02

# peer chaincode deploy -p github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02 -c '{"Function":"init", "Args": ["a","100", "b", "200"]}'

但无法从我自己的 github 路径运行 chainncode： https ://github.com/jeffyxia/hyperledger/trade

# peer chaincode deploy -p https://github.com/jeffyxia/hyperledger/trade -c '{"Function":"init", "Args": ["a","100", "b", "200"]}'

错误信息是：

错误：构建链代码时出错：rpc 错误：代码 = 2 desc = 获取错误

chaincode package bytes: Error getting code 'go get' failed with error: "exit status 2"

# github.com/jeffyxia/hyperledger/hello_world

/go/_usercode_/519629987/src/github.com/jeffyxia/hyperledger/hello_world/chaincode_example01.go:31: cannot use new(SimpleChaincode) (type *SimpleChaincode) as type shim.Chaincode in argument to shim.Start:

    *SimpleChaincode does not implement shim.Chaincode (wrong type for Init method)

        have Init(*shim.ChaincodeStub, string, []string) ([]byte, error)

        want Init(shim.ChaincodeStubInterface, string, []string) ([]byte, error)

补充资料：Ubuntu 16.04 没有go语言环境，使用PBFT算法。

如何解决这个问题，谢谢。

首先，您可能希望使用其官方存储库中的最新版本 Fabric。其次，错误是不言自明的，  *SimpleChaincode does not implement shim.Chaincode (wrong type for Init method)        have Init(*shim.ChaincodeStub, string, []string) ([]byte, error)        want Init(shim.ChaincodeStubInterface, string, []string) ([]byte, error)您需要替换 stub *shim.ChaincodeStub为stub shim.ChaincodeStubInterfacego 文件中的任何位置。请同时阅读此内容，https://github.com/IBM-Blockchain/ibm-blockchain-issues/issues/29
