yaml - Hyperledger Fabric configtxgen - 读取配置时出错 : map merge requires map or sequence of maps as the value

Question

我正在尝试使用以下内容设置一个简单的 Fabric 网络:

• 订购者组织 [abccoinOrderers]
• 示例组织 [ABC]

使用 cryptogen 工具生成所有必需的文件后，运行 configtxgen 命令会出现以下错误:

student@abc:~/Desktop/fabric/network$ configtxgen -profile DefaultBlockOrderingService -outputBlock ./config/genesis.block -configPath $PWD
    2019-12-26 12:35:42.131 MST [common.tools.configtxgen] main -> WARN 001 Omitting the channel ID for configtxgen for output operations is deprecated.  Explicitly passing the channel ID will be required in the future, defaulting to 'testchainid'.

    panic: Error reading configuration:  While parsing config: yaml: map merge requires map or sequence of maps as the value [recovered]
        panic: Error reading configuration:  While parsing config: yaml: map merge requires map or sequence of maps as the value

这是configtx.yaml

Organizations:
    - &abccoinOrderers
        Name: abccoinOrderersMSP
        ID: abccoinOrderersMSP
        MSPDir: crypto-config/ordererOrganizations/abccoin.com/msp
    - &ABC
        Name: ABCMSP
        ID: ABCMSP
        MSPDir: crypto-config/peerOrganizations/ABC.abccoin.com/msp
        AnchorPeers:
          - Host: Andy.ABC.abccoin.com
            Port: 7051

Application: &ApplicationDefaults

Orderer:
    - &DevModeOrdering
        OrdererType: solo
        Addresses:  
            - Devorderer.abccoin.com:7050
        BatchTimeout: 2s
        BatchSize:
            MaxMessageCount: 1

Profiles:
    DefaultBlockOrderingService:
        Orderer:
            <<: *DevModeOrdering
            Organizations:
                - *abccoinOrderers
        Consortiums:
            SampleConsortium:
                Organizations:
                    - *ABC


    abcMembersOnly:
        Consortium: SampleConsortium
        Application:
            <<: *ApplicationDefaults
            Organizations:
                - *ABC

我已经尝试重新排列代码块，如 this post 中所述.如本期 YML document "<<: value" cannot be parsed #245 中所述，我还尝试在引号中调整“<<”键的步调但它没有帮助。

configtx.yaml 中有 2 个错误。

1. Orderer:是map类型或者object类型，不是array或者slice类型。当您使用 - 定义参数时，它在 yaml 中用作数组。

Orderer:
    // remove -
    &DevModeOrdering
      OrdererType: solo
      Addresses:  
          - Devorderer.abccoin.com:7050
      BatchTimeout: 2s
      BatchSize:
          MaxMessageCount: 1

1. Application:您必须声明 Organizations: 参数。它可以是空的。如果你不声明任何东西，它就不会编译。要检查您应该尝试在任何在线转换器中将 yaml 转换为 json。

Application: &ApplicationDefaults
    Organizations:
