测试运行
安装环境
开始之前请先确认已经安装配置好Go语言环境，安装包可以从https://golang.org下载，如果连不Go的官网请自行百度下安装包。gttc现在支持Go版本为 1.9.x、1.10.x 及1.11.x。
$ go version
go version go1.11 darwin/amd64
下载gttc
$ go get github.com/TTCECO/gttc
$ cd $HOME/go/src/github.com/TTCECO/gttc
# 如果安装Go时，自己指定了GOPATH，则
$ cd $GOPATH/src/github.com/TTCECO/gttc
国内用go get会比较慢，也可以直接git clone代码，放入对应的目录。
编译
测试的时候，我们只需要进入cmd/gttc编译这一个文件即可。
$ cd $HOME/go/src/github.com/TTCECO/gttc/cmd/gttc
$ go build
如果没有任何提示，那恭喜你，编译成功了，你会发现当前目录下多了一个gttc的文件
运行测试
$ ./gttc --testnet
如果出现如下提示，则说明已经连上我们部署的ttc测试网络，开始进行同步。
