Hyperledger fabric GO下载依赖包util、shim、peer

go build 链码编译出现的问题：
github.com/hyperledger/fabric/core/chaincode/shim: module github.com/hyperledger/fabric@latest found (v2.1.1+incompatible), but does not contain package github.com/hyperledger/fabric/core/chaincode/shim
github.com/hyperledger/fabric-collect/chaincode/hello imports

解决方法：下载依赖包

临时设置Go mod
set GO111MODULE=on

在当前目录中初始化新模块
go mod init chaincode //当前目录会多出文件夹go mod

下载依赖包
go get github.com/hyperledger/fabric/common/[email protected] //1.4版本

go get github.com/hyperledger/fabric/core/chaincode/[email protected]

go get github.com/hyperledger/fabric/protos/[email protected]

编译自己的go链码，生成二进制文件
go build -tags nopkcs11 hello.go //不需要pkcs11包，因为该包含有C代码
