我想测试Fabric Go SDK。然后克隆this存储库 我按照以下步骤操作：
$ make populate
$ go run fabric-cli.go
$ make example-network
打开另一个shell并转到CLI目录
$ cd $GOPATH/src/github.com/securekey/fabric-examples/fabric-cli/cmd/fabric-cli
然后我想创建频道mychannel
$ go run fabric-cli.go channel create --cid mychannel --txfile ../../fabric-sdk-go/test/fixtures/fabric/v1.1/channel/mychannel.tx --config ../../test/fixtures/config/config_test_local.yaml
但是我得到了错误：
