Question

当我跑

时

composer network start -c PeerAdmin@hlfv1 -a test-network.bna -A admin -S adminpw

花了很长时间才得到超时错误

Error: Error trying to instantiate composer runtime. Error: No valid responses from any peers.
Response from attempted peer comms was an error: Error: REQUEST_TIMEOUT

docker ps

$ docker ps

composer network start命令正在创建一个新的docker容器并在该容器中使用npm install，因此您的超时可能是系统创建容器的速度慢和/或npm install命令性能降低的结果。

默认超时为300秒，但您可以使用环境变量public class User { @OneToMany(mappedBy = "sender") private List<Request> senderOf; @OneToMany(mappedBy = "receiver") private List<Request> receiverOf; }

增加该值

如果查看用于启动Fabric的docker-compose yaml文件（特别是Peer），则可以为此环境变量添加一行。

如果您使用的是默认的Dev Fabric，那么您要查找的文件可能是：CORE_CHAINCODE_EXECUTETIMEOUT=800s

v0.18.1错误，无法启动网络
