正在运行的Fabcar示例返回错误：未能批准安装链码

Question

我在Ubuntu 19.10上，已安装所有先决条件，并已下载fabric-samples git存储库。

我正在关注此link的教程

我运行了第一个网络示例，它运行良好。现在，当我尝试通过运行命令./startFabric.sh javascript运行fabcar示例时，出现以下错误：

...

看起来好像在执行时产生了错误：

docker exec -e CORE_PEER_LOCALMSPID=Org2MSP -e CORE_PEER_ADDRESS=peer0.org2.example.com:9051 -e CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/[email protected]/msp -e CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt cli peer --tls=true --cafile=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem --orderer=orderer.example.com:7050 lifecycle chaincode install fabcar.tar.gz

我假设我使用最新版本的hyperledger-fabric v2.0.0，因为我在fabric-samples存储库的master分支中。我在做什么错？

Answer 1

我将删除安装结构二进制文件的原始目录，并清理docker中的所有内容。确保您的环境干净。并在启动fabcar脚本之前设置PATH。

祝你好运。>>
