ubuntu16.04 fabric-sample 中测试网络中设置链码问题

问题：
fabric samples在执行./network.sh deployCC时会报以下错误：
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 "

解决：

一、更换go语言版本，1.13 -> 1.15
1.下载

curl -L https://golang.google.cn/dl/go1.15.linux-amd64.tar.gz -o go1.15.linux-amd64.tar.gz

2.解压

sudo tar -C /usr/local -xzf go1.15.linux-amd64.tar.gz

3.配置环境变量

vim ~/.bashrc

在文件中添加以下语句

export GOPATH
