Error: Error trying to instantiate composer runtime. Error: No valid responses from any peers.
Response from attempted peer comms was an error: Error: chaincode error (status: 500, message: chaincode instantiation policy violated(Failed to authenticate policy))

Answer 1

错误“错误：尝试实例化 Composer 运行时时出错。” 表明您尚未运行composer运行时安装命令，例如 composer runtime install -c PeerAdmin@fabric-network -n tutorial-network 或者该命令未成功完成。

另一种可能是您的织物已停止或无法接触。
