我无法在Hyperledge Fabric中实例化chaincode。

执行时:

peer chaincode instantiate -o orderer -n test_cc -C test-channel -v 0.1 -c '{"Args":["initLedger"]}'

我得到错误:
peer0       | 2018-04-17 13:02:11.097 UTC [dockercontroller] Start -> ERRO 046 start-could not start container: API error (400): {"message":"OCI runtime create failed: container_linux.go:348: starting container process caused \"exec: \\\"chaincode\\\": executable file not found in $PATH\": unknown"}

在Internet上搜索时,错误消息与[OCI Runtimer Error when installing Hyperledger Chaincode via Java-SDK和[OCI runtime error when sending Hyperledger Fabric's chaincode instantiation request to peers]上的原始帖子相同,但这些帖子上的评论并没有使我找到解决方案。

我正在使用以下软件版本:
super 账本1.1.0
Docker版本18.03.0-ce(在Linux上),Hyperledger Docker镜像:x86_64-1.1.0

成功执行以下步骤:
  • 构建链码。该代码编译没有错误。除了两个必需的“github.com/hyperledger/fabric/core/chaincode/shim”和
    “github.com/hyperledger/fabric/protos/peer”
  • 包装链码。
  • 签名链码。
  • 安装chaincode(它最终出现在对等方的/var/hyperledger/production/chaincodes/test_cc.0.1中。

  • (根据Hyperledger文档的步骤:[http://hyperledger-fabric-docs.readthedocs.io/en/latest/chaincode4noah.html]]

    在CLI Docker容器中,文件位于目录/opt/gopath/src/chaincode/go/test_cc/中,该目录中存在4个文件:test_cc, test_cc.go, test_cc_pack.out, test_cc_signed_pack.out(二进制文件,源文件,打包文件和签名打包文件)。

    似乎存在一些路径问题,但是链代码容器的创建过程以及影响该过程的变量。

    我现在已经把这个问题弄乱了几天(!),尝试了所有路径组合,例如将文件放在/opt/gopath/bin等中,但无济于事。

    谁能在这个问题上大放异彩?还是知道正确的路径是什么,它们在哪里,或者应该在哪里定义?

    谢谢

    最佳答案

    问题是在Go源文件中,我使用了“package test_package”,在构建时,它不会创建可执行文件,而是可链接的目标文件。

    在Go文件中包含“package main”,然后进行重建和重新打包,使“peer chaincode安装”和“peer chaincode实例化”命令按预期工作。
