执行以下指令安装链码时报错
peer lifecycle chaincode install basic.tar.gz
Error: chaincode install failed with status: 500 - failed to invoke backing implementation of 'InstallChaincode': could not build chaincode: docker build failed: docker image build failed: docker build failed: Error returned from build: 1 "go: github.com/golang/protobuf@v1.3.2: Get "https://proxy.golang.org/github.com/golang/protobuf/@v/v1.3.2.mod": dial tcp 172.217.24.17:443: connect: connection refused
解决方案，到链码所在的目录下提前下载依赖包
cd fabric-samples/asset-transfer-basic/chaincode-go
更改go代理
go env -w GOPROXY=https://goproxy.io,direct go env -w GO111MODULE=on go mod vendor
重新打包智能合约并安装链码
peer lifecycle chaincode package basic.tar.gz --path ../asset-transfer-basic/chaincode-go/ --lang golang --label basic_1.0 peer lifecycle chaincode install basic.tar.gz
成功解决Error: chaincode install failed with status: 500 - failed to invoke backing implementation of 'InstallChaincode': could not build chaincode: docker build failed: docker image build failed: docker build failed: Error returned from build: 1 "go: github.com/golang/protobuf@v1.3.2: Get "https://proxy.golang.org/github.com/golang/protobuf/@v/v1.3.2.mod": dial tcp 172.217.24.17:443: connect: connection refused的问题。
