Hyperledger Fabcar：错误：无法组装交易，错误提案响应不成功

Question

我试图在我的本地机器上运行最新的 Fabric 1.4 Fabcar。 iv 安装了清理 docker 镜像的先决条件并运行以下命令

fabric-samples/fabcar: ./startFabric.sh java

我可以看到正在对等节点上安装的链代码，但是一旦它到达通道，我就会收到以下错误

`错误：无法组装交易，错误提案响应不成功，错误代码500，msg链码注册失败：容器退出254'

我也试过了

./startFabric.sh javascript and ./startFabric.sh

但我得到了相同的结果。我能够运行并查询 '''first-network''' ok，但无法启动 Fabcar :(

另外，如果我从 java 应用程序进行 mvn 测试，我会得到 ​​p>

Answer 1

失败的原因可能有很多，要么是路径设置不正确，要么是链码安装的对等点可能无法访问。

您可以尝试使用这些命令并尝试再次启动

docker kill $(docker ps -q) docker rm $(docker ps -aq) docker rmi $(docker images dev-* -q)

Answer 2

因此，解决问题的根本问题 java.net.UnknownHostException 问题的解决方案是通过添加以下内容来更改 /etc/hosts 中的系统主机文件...

127.0.0.1 orderer.example.com

127.0.0.1 peer1.org1.example.com
127.0.0.1 peer0.org2.example.com
127.0.0.1 peer0.org1.example.com
127.0.0.1 peer1.org2.example.com

127.0.0.1 ca_peerOrg1
127.0.0.1 ca_peerOrg2
127.0.0.1 couchdb1 
127.0.0.1 couchdb2
127.0.0.1 couchdb3
127.0.0.1 couchbd0

mvn 测试然后 :) 希望这对其他人有所帮助
