Hyperledger- composer : composer网络启动错误:Error: REQUEST_TIMEOUT命令失败

Question

在我创建了一个程序并完成了模型设计/ query.qry / acl之后。我在当地的游乐场测试了它，它运行成功。当我尝试创建管理卡(运行composer network start)时，我失败了。它启动了一个ccenv对等体，但没有响应。

我在谷歌中找不到任何其他类似的错误。这让我很困惑。

预期的Behavior Composer网络启动命令应成功运行。并且应该正确地创建管理卡。

实际行为无法创建卡片。用一个随机的名字发起了一个奇怪的同龄人。当我再次尝试运行:composer network start -n cmusic PeerAdmin@hlfv1peeradmin@hlfv1 -V 0.0.1 -A admin -S adminpw时，它显示已经启动。

可能的修复我不知道为什么和如何修复它。我尝试重新加载环境，但同样的错误仍然存在。

Answer 1

我已经解决了这个问题。关键是在同一时间网络中只能有一个链码。如果同时部署多个，则会出现此错误。

尝试这两种方法并重新启动网络。

docker stop $(docker ps -aq) docker container prune
