v1.4 版本执行 ./byfn.sh up时，报如下错误

Error: error getting chaincode deployment spec for mycc: error getting chaincode package bytes: failed to calculate dependencies: incomplete package: github.com/hyperledger/fabric/core/chaincode/shim
!!!!!!!!!!!!!!! Chaincode installation on peer0.org1 has failed !!!!!!!!!!!!!!!!
========= ERROR !!! FAILED to execute End-2-End Scenario ===========

跟脚本代码是从（github）以下逻辑报出的

installChaincode() {
  PEER=$1
  ORG=$2
  setGlobals $PEER $ORG
  VERSION=${3:-1.0}
  set -x
  peer chaincode install -n mycc -v ${VERSION} -l ${LANGUAGE} -p ${CC_SRC_PATH} >&log.txt // 此处
  res=$?
  set +x
  cat log.txt
  verifyResult $res "Chaincode installation on peer${PEER}.org${ORG} has failed"
  echo "===================== Chaincode is installed on peer${PEER}.org${ORG} ===================== "
  echo
}

跟下逻辑，意思是说，以下依赖未找到（github）

import (
    "fmt"
    "strconv"

    "github.com/hyperledger/fabric/core/chaincode/shim" // 未找到
    pb "github.com/hyperledger/fabric/protos/peer"
)

经过对比仓库分支代码，发现release-1.4是有的，最新的master分支已经删掉了。
直接参考2.0版本修改下吧
修改chaincode_example02.go

import (
    "bytes"
    "encoding/json"
    "fmt"
    "strconv"
    "strings"
    "time"
    "os"

    "github.com/hyperledger/fabric-chaincode-go/shim"
    pb "github.com/hyperledger/fabric-protos-go/peer"
)

并在同级目录新建go.mod

module github.com/hyperledger/fabric/scripts/fabric-samples/chaincode/chaincode_example02/go

go 1.14
require (
        github.com/hyperledger/fabric-chaincode-go v0.0.0-20200128192331-2d899240a7ed
        github.com/hyperledger/fabric-protos-go v0.0.0-20200124220212-e9cfc186ba7b
        golang.org/x/net v0.0.0-20200202094626-16171245cfb2 // indirect
        golang.org/x/sys v0.0.0-20200212091648-12a6c2dcc1e4 // indirect
        golang.org/x/text v0.3.2 // indirect
        google.golang.org/genproto v0.0.0-20200218151345-dad8c97a84f5 // indirect
)

然后更新依赖

go mod vendor

再次重新执行测试就好了

./byfn.sh down
./byfn.sh up

或者

go mod init chaincode
go get github.com/hyperledger/fabric/common/util@v1.4
go get github.com/hyperledger/fabric/core/chaincode/shim@v1.4
go get github.com/hyperledger/fabric/protos/peer@v1.4
