go+realize实现热更新

看看作者对它的描述：

Realize is the Golang Task Runner which enhance your workflow by automating the most common tasks and using the best performing Golang live reloading.

习惯了webpack多年，Golang Web开发环境中怎么能少了热更新功能呢，于是搜索发现一款还不错的工具，在我的windows机器上安装，过程中发现了三个坑，还好最终都解决了。好了，上教程！

安装realize

因为之前项目里面安装了 gin 作为 web 框架，所以路由都已经写好了，供后面测试的时候用。

go get github.com/oxequa/realize

安装的时候可能会提示安装某个包失败（golang.org开头），不用慌，这几个包可以去 golang 的仓库克隆下来，放到 $GOPATH/src/golang.org/x 目录下。

配置

realize initpkill

修改realize包

依次执行下面命令

cd /go/src/github.com/oxequa/realize
git fetch
git checkout v2.0.2
go get github.com/oxequa/realize

realize start
