我正在尝试在raspberry上创建网络hyperledger，为了测试它我开始从官方hyperledger存储库下载的基本网络。我使用官方docker repo中的frbrkoala图像版本armv7l-1.0.1修改了docker-compose.yml文件，但是我在创建频道时遇到了问题。我的输出是：
# Create the channel
docker exec -e "CORE_PEER_LOCALMSPID=Org1MSP" -e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/Admin@org1.example.com/msp" peer0.org1.example.com peer channel create -o orderer.example.com:7050 -c mychannel -f /etc/hyperledger/configtx/channel.tx
