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))
推荐答案
Error: No valid responses from any peers可能是b/c，您不是./startFabric(在fabric-tools文件夹中)，也可能是.acl文件(权限. ACL)有错误(尝试将其更改为初始版本).
Error: No valid responses from any peers may be b/c you don't ./startFabric (in fabric-tools folder) or may be the .acl file (permissions.acl) have error (try change it to the beginning version).
