hyperledger-fabric - Fabric v1.3 链码在导入“shim/ext/statebased”时无法实例化

问题描述

由于我尝试了 Fabric v1.3 的新功能：key-level-endorsement从此文档中，我必须通过 KeyEndorsementPolicy.Policy() 函数生成我的密钥级背书策略。

但是，导入包后无法实例化链码github.com/hyperledger/fabric/core/chaincode/shim/ext/statebased

以下是错误日志：

2018-12-11 09:58:25.518 UTC [dockercontroller] deployImage -> ERRO 053 Error building images: Failed to generate platform-specific docker build: Error returned from build: 1 "opt/gopath/src/github.com/hyperledger/fabric/core/chaincode/shim/ext/statebased/statebasedimpl.go:14:2: cannot find package "github.com/hyperledger/fabric/common/cauthdsl" in any of:
    /opt/gopath/src/github.com/hyperledger/fabric/vendor/github.com/hyperledger/fabric/common/cauthdsl (vendor tree)
    /opt/go/src/github.com/hyperledger/fabric/common/cauthdsl (from $GOROOT)
    /chaincode/input/src/github.com/hyperledger/fabric/common/cauthdsl (from $GOPATH)
    /opt/gopath/src/github.com/hyperledger/fabric/common/cauthdsl
"

我知道这意味着ccenv容器缺少这种依赖，所以我尝试将我vendor的 gopath 目录添加到我的实例化请求的链码路径目录。然后我又试了一次，仍然有错误：

我怀疑图像中仍然缺少一些 c/c++ 库ccenv。

[]byte那么，如果没有这个，我怎么能生成一个关键级别的背书策略KeyEndorsementPolicy呢？或者，我怎样才能导入这个shim/ext/statebased包？

解决方案

那是因为 fabric-sdk-node 的一个错误，这里是链接。

升级到fabric-client@1.3.0后，问题解决：

npm install fabric-client@1.3.0
npm install fabric-ca-client@1.3.0
