缺少的第三方依赖包已重新添加到 vendor/ 中，现在应该可以了。麻烦你重新拉取一下

$ go get -u github.com/EDDYCJY/go-gin-example

from go-gin-example.

还有错误

@weihuahuang 你是 windows 系统？

from go-gin-example.

是的

from go-gin-example.

@weihuahuang Windows 的话，把这块代码放出来：https://github.com/EDDYCJY/go-gin-example/blob/master/main.go#L39-L48

平滑重启这块的代码 Windows 不支持，因此要注释掉：https://github.com/EDDYCJY/go-gin-example/blob/master/main.go#L51-L62

from go-gin-example.

@weihuahuang 你环境上 runtime.GOOS 输出出来的值是什么呢？

from go-gin-example.

删除了项目，重新拉取的时候报错。

@weihua2018 你应该

$ go get -u github.com/EDDYCJY/go-gin-example

from go-gin-example.

另外如果你是 windows 系统的话，应该把如下代码打开注释：https://github.com/EDDYCJY/go-gin-example/blob/master/main.go#L36-L46

把 endless 的相关代码给注释了：https://github.com/EDDYCJY/go-gin-example/blob/master/main.go#L48-L59
