hyperledger-fabric - Hyperledger Composer v0.16.0 网络启动错误

Question

我正在尝试 Hyperledger Composer v0.16.0。根据这个procedure ，我想将 BNA 部署到云端的 Fabric 网络。但发生以下错误。
请让我知道如何解决它。

命令:

composer network start --card PeerAdmin@myfabric --networkAdmin admin --networkAdminEnrollSecret adminpw --archiveFile trade-network.bna --file networkadmin.card

结果:

tarting business network from archive: trade-network.bna
Business network definition:
    Identifier: trade-network@0.1.13
    Description: Commodities Trading Business Network

Processing these Network Admins: 
    userName: admin

✖ Starting business network definition. This may take a minute...
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

Error: No valid responses from any peers可能是 b/c 你没有 ./startFabric (在 fabric-tools 文件夹中)或者可能是 .acl文件 (permissions.acl) 有错误(尝试将其更改为初始版本)。
