我正在尝试在本地计算机上运行最新的Fabric 1.4 Fabcar。 iv安装先决条件清理docker映像并运行以下命令
fabric-samples/fabcar: ./startFabric.sh java
我可以看到链码已安装在对等节点上，但是一旦到达频道，我就会收到以下错误消息
`错误：无法组装交易，错误的提案响应未成功，错误代码500，味精链码注册失败：容器退出并显示254'
IV也尝试过
./startFabric.sh javascript and ./startFabric.sh
但是我得到相同的结果。我可以运行并查询'''first-network'''，但是无法启动Fabcar :(
如果我从Java应用程序执行mvn测试，我也会得到
Caused by: org.hyperledger.fabric.sdk.exception.TransactionException:

失败的原因可能很多，要么路径设置不正确，要么安装的链码对等体无法访问。
您可以使用这些命令尝试一下，然后尝试重新启动
docker kill $（泊坞窗ps -q） 泊坞窗rm $（docker ps -aq） 泊坞窗rmi $（泊坞窗图像dev- * -q）

因此解决java.net.UnknownHostException问题的解决方案是该问题的根本问题，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
然后mvn测试成功了：)希望这对其他人有帮助
