我尝试通过修改来自build your first networkchaincode_example02的 byfn 脚本在我提出的网络上安装和实例化链代码。我正在使用 2 个组织，每个组织有 1 个同伴。我重命名了组织。

对等容器即将出现，我能够在两个组织的对等设备上安装链代码。当我实例化时，链码容器出现了。该命令不返回任何错误。

但我无法查询链码。我无法在peer chaincode list --instantiated -C mychannel.

我尝试在不进行任何修改的情况下运行 byfn 脚本，并且能够完成端到端测试。

生成后的链码容器连接到与对等节点和排序节点不同的网络。我更改了文件中的CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE属性peer-base.yaml以匹配文件中的网络docker-compose-cli.yaml以解决此问题。

它清楚地表明对等方无法连接订购者

[OrdererMSP] >> 为什么它出现在 orderer 端点列表中？我假设你做错了什么

[{localhost:7050 [OrdererMSP]}]<<< 错误的表示

请在此处粘贴 peer manifest、orderer manifest 和 configtx.yaml

为了调查问题
