go - 实例化链码时出错

Question

请帮我解决这个问题，当我实例化我的链代码时发生错误:

目前，我猜测问题与shim包有关，因为我在我的utils包中删除了它，实例化成功。

我的链码:

import (
    "bytes"
    "encoding/hex"
    "encoding/json"
    "fmt"
    "strconv"

    "github.com/golang/protobuf/proto"
    "github.com/hyperledger/fabric/core/chaincode/shim"
    "github.com/hyperledger/fabric/protos/msp"
    pb "github.com/hyperledger/fabric/protos/peer"
    "github.com/myproj/models"
    "github.com/myproj/packages/utils"
)

APIstub shim.ChaincodeStubInterface
...
username, _ = utils.GetCurrentUser(APIstub)
...

我的包裹

package utils

import (
    "github.com/hyperledger/fabric/core/chaincode/shim"
    "golang.org/x/crypto/bcrypt"
)

func GetCurrentUser(stub shim.ChaincodeStubInterface) (string, error) {
    cert, err := GetCreatorCert(stub)

    return cert.Subject.CommonName, err
}

问题:

Error: Error endorsing chaincode: rpc error: code = Unknown desc = error starting container: Failed to generate platform-specific docker build: Error returned from build: 2 "# ~vendor/github.com/hyperledger/fabric/vendor/github.com/docker/docker/pkg/archive ~vendor/github.com/hyperledger/fabric/vendor/github.com/docker/docker/pkg/archive/archive.go:364:5: hdr.Format undefined (type *tar.Header has no field or method Format) ~vendor/github.com/hyperledger/fabric/vendor/github.com/docker/docker/pkg/archive/archive.go:364:15: undefined: tar.FormatPAX ~/vendor/github.com/hyperledger/fabric/vendor/github.com/docker/docker/pkg/archive/archive.go:1166:7: hdr.Format undefined (type *tar.Header has no field or method Format) ~/vendor/github.com/hyperledger/fabric/vendor/github.com/docker/docker/pkg/archive/archive.go:1166:17: undefined: tar.FormatPAX

结构版本 1.1.0

转到版本 1.9.2

将 fabric 升级到 1.2.0 后，我遇到了同样的问题。 Fabric 1.2.0 需要 go 1.10.x。所以我将 go lang 升级到 1.10.3，它的效果非常好。
