go mod无法找到依赖项的版本v0.0.0-00010101000000-000000000000

Question

我试图通过Go mod下载项目的所有依赖项；在CLI上执行Go mod供应商时会出现问题。产出如下：

go: finding github.com/hyperledger/fabric-sdk-go v0.0.0-00010101000000-000000000000
go: github.com/hyperledger/fabric-sdk-go@v0.0.0-00010101000000-000000000000: unknown revision 000000000000
go: error loading module requirements

导入库的代码如下：

import (    
    "github.com/hyperledger/fabric-sdk-go/pkg/client/ledger"
    "github.com/hyperledger/fabric-sdk-go/pkg/client/resmgmt"
    "github.com/hyperledger/fabric-sdk-go/pkg/fabsdk"
)

krakengosdk是我正在处理的包的名称：

go mod init krakengosdk

有解决办法吗？我已经研究了一段时间，但没有发现任何有用的东西。

更新：我已经将Go版本更新为1.13；似乎错误必须与“github.com/hyperledger/fabric-sdk-go/test/integration@v0.0.0-20190918153951-5d7ae7a5be8f”：一起使用。

go get -v github.com/hyperledger/fabric-sdk-go/test/integration@latest
go: finding github.com/hyperledger/fabric-sdk-go/test/integration latest
go get: github.com/hyperledger/fabric-sdk-go/test/integration@v0.0.0-20190918153951-5d7ae7a5be8f requires

Proposed diagnostics

I suggest to try those commands in console (bash/dash/fish/zsh):

# 1. Create clean project 
$ mkdir /tmp/checkmods && cd /tmp/checkmods  # create clean directory
$ export GO111MODULES=on
$ go version # check that version 1.13
$ go mod init main # name of package does not matter here

# 2. Install packages, check output
$ go get -v github.com/hyperledger/fabric-sdk-go/pkg/client/ledger
$ go get -v github.com/hyperledger/fabric-sdk-go/pkg/client/resmgmt
$ go get -v github.com/hyperledger/fabric-sdk-go/pkg/fabsdk

# 3. Create main.go 
$ touch main.go
$ # edit main.go, add imported packages, import something from those packages
$ go mod vendor 
# Do you have problems here? 
# if you encounter problems: 
# - play around  with `go mod tidy`
# - look at `go.mod` and `go.sum`
# - `go mod graph/verify/why` - are your friends

Example of main.go:

package main

import (
    "fmt"
    "github.com/hyperledger/fabric-sdk-go/pkg/client/ledger"
    "github.com/hyperledger/fabric-sdk-go/pkg/client/resmgmt"
    "github.com/hyperledger/fabric-sdk-go/pkg/fabsdk"
)

func main() {
    var (
        cln  &ledger.Client
        rsm  &resmgmt.Client
        fbs  &fabsdk.FabricSDK
    )
    fmt.Printf("%T %T %T
", cln, rsm, fbs)
}

Analysis

If you encounter problems: explain on which line you encountered, what kind of problem.

If everything OK with clean start: look what is different between your project and clean start (diffs for go.sum & go.mod)

Good luck!
