hyperledger 2.0 go:unknown subcommand "mod"

2.0으로 체인코드 설치를 진행하다 아래와 같은 문제가 발생하였다.

$./network.sh deployCC
deploying chaincode on channel 'mychannel'

Vendoring Go dependencies ...
/opt/gopath/src/github.com/hyperledger/fabric-samples/chaincode/fabcar/go /opt/gopath/src/github.com/hyperledger/fabric-samples/test-network

Error: error getting chaincode bytes: listing deps for package ../chaincode/fabcar/go/ failed: exit status 2
!!!!!!!!!!!!!!! Chaincode packaging on peer0.org1 has failed !!!!!!!!!!!!!!!!

ERROR !!! Deploying chaincode failed

 

원인은 Golang 버전 이슈.

Go언어를 1.14버전으로 다시 설치해준다.

설치를 위해선 기존 버전을 지워주고 해야된다.(필자의 go dir은 /opt/go)

cd /usr/local/
sudo wget https://storage.googleapis.com/golang/go1.14.linux-amd64.tar.gz
sudo rm -rf /opt/go
sudo tar -C /opt -xzf go1.14.linux-amd64.tar.gz
go version
go version go1.14 linux/amd64

sudo vi /etc/profile

export GOPATH="/opt/gopath"
export GOROOT="/opt/go"
export PATH=$GOROOT/bin:$GOPATH/bin:$PATH

 

설치하고 디시 시도하면 정상 동작하는 것을 확인할 수 있다.
