Error: Error trying install business network. Error: No valid responses from any peers. Response from attempted peer comms was an error: Error: Failed to connect before the deadline

即使所有容器都已启动并正在运行，错误仍然存​​在。 当我执行以下命令时：-

bcuser@CUSVLDEV1HFB01:~/fabric-dev-servers/tutorial-network$ composer network install --card PeerAdmin@hlfv1 --archiveFile tutorial-network@0.0.1.bna
â Installing business network. This may take a minute...
Error: Error trying install business network. Error: No valid responses from any peers.
Response from attempted peer comms was an error: Error: Failed to connect before the deadline
Command failed

查看屏幕截图并查看卡片，看来您以前已经连接OK，并且能够部署测试业务网络。因此，看起来您尝试连接的Fabric似乎不可用（未启动？）

您是否重新启动了承载Fabric的计算机？

在承载Fabric的计算机上，尝试使用命令docker ps，查看是否有任何Dock容器正在运行。您也可以尝试docker ps -a查看所有容器是否正在运行。

如果您的Fabric未运行，并且使用了Composer工具提供的“ Development Fabric”，请please see this posting了解startFabric.sh脚本的工作原理。
