在尝试实例化我的链码时,我收到以下错误:
2018-06-19 09:03:09.526 UTC [chaincodeCmd] checkChaincodeCmdParams -> INFO 001 Using default escc
2018-06-19 09:03:09.526 UTC [chaincodeCmd] checkChaincodeCmdParams -> INFO 002 Using default vscc
Error: Error endorsing chaincode: rpc error: code = Unknown desc = chaincode error (status: 500, message: cannot get package for chaincode (fabrep:1.0))
有人能说出这意味着什么吗?以及如何解决错误?

确保在尝试实例化之前先将链码安装在对等方上。
使用安装命令:
peer chaincode install ...
您可以使用此处的文档作为指南:https://hyperledger-fabric.readthedocs.io/en/release-1.1/commands/peerchaincode.html#peer-chaincode-install

首先检查对等方是否已安装链码
$ peer chaincode list --installed
并使用已安装的链码的确切名称运行instantiate
命令
