Hyperledger Fabric 通道块不是使用 golang 创建的，而是使用手动 cli 成功创建的

Question

我在 Go 中有一个自动生成通道配置块的程序。如果我使用终端手动执行它，它会成功生成一个块，如下所示：

export CORE_PEER_ADDRESS=peer0.debutinfotech.com:7051
export CORE_PEER_LOCALMSPID=debutinfotechMSP
export CORE_PEER_MSPCONFIGPATH=/home/akshay/go/src/ConfigTool/Go/network/crypto-config/peerOrganizations/debutinfotech.com/users/Admin@debutinfotech.com/msp
export FABRIC_CFG_PATH=/home/akshay/.fabdep/config
peer channel create -o orderer0.example.com:7050 -f network/channel-artifacts/mychannel.tx -c mychannel
2018-11-19 16:28:16.162 IST [channelCmd] InitCmdFactory -> INFO 001 Endorser and orderer connections initialized
2018-11-19 16:28:16.205 IST [cli/common] readBlock -> INFO 002 Got status: &{NOT_FOUND}
2018-11-19 16:28:16.205 IST [channelCmd] InitCmdFactory -> INFO 003 Endorser and orderer connections initialized
2018-11-19 16:28:16.413 IST [cli/common] readBlock -> INFO 004 Received block: 0

我可以在目录中看到mychannel.block。

但是当我使用 Go 程序做同样的事情时。它会抛出如下所示的错误：

2018-11-19 16:22:42.639 IST [channelCmd] InitCmdFactory -> INFO 001 Endorser and orderer connections initialized
2018-11-19 16:22:42.644 IST [common/tools/configtxgen/localconfig] Load -> CRIT 002 Error reading configuration:  Unsupported Config Type ""

程序源代码如下：

dir := utils.GetRootDir()

        os.Setenv("CORE_PEER_MSPCONFIGPATH", *peerOrg.UserDir+"/Admin@"+peerOrg.OrgDomain+"/msp")
        os.Setenv("CORE_PEER_LOCALMSPID", peerOrg.MSPID)
        os.Setenv("CORE_PEER_ADDRESS", "peer0."+peerOrg.OrgDomain+":7051")
        os.Setenv("FABRIC_CFG_PATH", os.ExpandEnv("$HOME")+"/.fabdep/config")
        command := exec.Command("peer", "channel", "create", "-o", "orderer0."+ordererOrg.OrgDomain+":7050", "-c", channel.Name, "--outputBlock", dir+"/network/"+channel.Name+".block")
        command.Env = os.Environ()

        result, err := command.CombinedOutput()

我已经设置了与终端相同的 FABRIC_CFG_PATH 路径，但我仍然不知道这有什么问题。

非常感谢任何建议/评论。

CORE_PEER_MSPCONFIGPATH 不正确。设置正确的路径解决了我的问题
