背书者实例化具有错误“找不到包"的链码. [英] Endorsers Instantiate Chaincode with error "cannot find package"

问题描述

我创建了一个链码，并向其中导入了一个包.

I created a chaincode and I imported a package to it.

import (
"bytes"
"encoding/json"
"fmt"
"strings"
"golang.org/x/crypto/bcrypt"
"github.com/hyperledger/fabric/core/chaincode/shim"
    pb "github.com/hyperledger/fabric/protos/peer")

我可以将该链码安装到所有背书人.但是当我将其实例化给所有背书人时，它遇到了错误:

I can install that chaincode to all endorsers. But when I instantiated it to all endorsers, it faced the error:

endorser failed with error starting container: error starting container: Failed to generate platform-specific docker build: Error returned from build: 1 "/chaincode/input/src/github.com/marbles02/marbles_chaincode.go:85:2: cannot find package "golang.org/x/crypto/bcrypt" in any of:
/usr/local/go/src/golang.org/x/crypto/bcrypt (from $GOROOT)
/chaincode/input/src/golang.org/x/crypto/bcrypt (from $GOPATH)
/go/src/golang.org/x/crypto/bcrypt

我试图将golang.org/x/crypto/bcrypt程序包复制到根目录中的/usr/local/go/src/，但是它具有相同的错误.

I tried to copy golang.org/x/crypto/bcrypt package to the /usr/local/go/src/ in the root directory, but it has the same error.

推荐答案

尝试使用以下命令在chaincode目录中安装依赖项:

Try Installing the dependencies in the chaincode directory using below commands:

1. go mod init将创建go.mod和go.sum文件.
2. go mod vendor用于创建vendor目录.

1. go mod init will create go.mod and go.sum files.
2. go mod vendor for creating a vendor directory.

此外，如果使用fabric:v2.X.X，则shim和peer程序包将移至其他库. 因此，将chainc.go文件中的peer和shim软件包更改为下面的内容.

Also if using fabric:v2.X.X then shim and peer packages moved to different libraries. so change the peer and shim packages to below in the chaincode.go file.

1. peer-> github.com/hyperledger/fabric-protos-go/peer.
2. shim-> github.com/hyperledger/fabric-chaincode-go/shim

1. peer --> github.com/hyperledger/fabric-protos-go/peer.
2. shim --> github.com/hyperledger/fabric-chaincode-go/shim

在运行go mod init命令之前，请确保添加peer和shim更改，或者如果您已经具有vendor目录，请尝试依次按go mod tidy和go mod vendor命令来更新软件包.

Make sure to add peerand shim changes before running go mod initcommand OR if you are already have a vendor directory then try go mod tidy and then go mod vendor commands to update the packages.
