在Peer节点执行下载chaincode命令时：

peer lifecycle chaincode install sacc.tar.gz

报错：

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: 2 "google.golang.org/protobuf/internal/flags

原因：

sacc.tar.gz 中 vendor中文件不全

解决方法：

根据你对应的fabric版本，去下载对应的 vendor、go.sum、go.mod

，将它们放到 对应的文件夹下

-------------------------------更新
（可以一试，但俺也不知道能否解决了）

-------------------------------再更新
上面的方法好像不对，sorrysorry

我现在用的 1.14版本的Go
在运行代码前可以执行

export GO111MODULE=on
export GOPROXY=https://goproxy.cn

设置Go依赖中国区下载路径。

在打包智能合约时，先执行

export GO111MODULE=on
export GOPROXY=https://goproxy.cn
go mod vendor

设置Go依赖中国区下载路径，并将依赖包下载到vendor中。

尝试上面的方法后，我就没遇到过这样的错了。
