godep：exec：“执行”：在$ PATH中找不到可执行文件？

I am trying to run make run. But getting this. I do not know to how to set this.

You need to set the path variable to where your go package is installed. Typically on ubuntu is installed on the /bin folder. So in your case you have to set it to:

$ export PATH=$PATH:$GOPATH/bin
