docker - Fabric v1.2教程调用失败:build your first network

Question

当我按照 fabric(v1.2) (link here) 的教程执行调用以下命令时

peer chaincode invoke -o orderer.example.com:7050 --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n mycc --peerAddresses peer0.org1.example.com:7051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --peerAddresses peer0.org2.example.com:7051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt -c '{"Args":["invoke","a","b","10"]

我收到一个错误。

orderer 容器也会打印如下的日志消息:

Answer 1

我在使用这个“构建你的第一个网络教程”时遇到了类似的问题(在 Fabric v1.2 中使用 Invoke)。
在运行查询和调用命令之前在 org2 上安装 mycc 链代码为我解决了这个问题。
因此，您可以尝试将环境变量更改为 org2，然后再次运行 peer chaincode install 命令(这次将针对 org2)。之后，您应该能够运行查询并调用命令。

总之，试着用这个单线再去吧:
