Go，Golang：使用GOROOT导入外部软件包

Question

Go, Golang : does not make sense that I have to have files before import

I am trying to go to next step but keep getting errors

1. I have the package that I want to import ready.
2. All I need to do is to import the external package from github and be able to use it on any code.

So this is what I did.

mkdir $HOME/go
export GOPATH=$HOME/go
go get github.com/user/project

This runs successfully. I downloaded it onto here with source code files from github

/Users/user/go/src/github.com/user/project/project.go

So to use this package that I just import I do

go run /Users/user/Desktop/code.go

But I am getting the following errors

 MacBook-Air:~ user$ go run /Users/user/Desktop/code.go 
 Desktop/code.go:32:8: cannot find package "project" in any of:
        /usr/local/go/src/pkg/project (from $GOROOT)
        /Users/user/go/src/project (from $GOPATH)

What should I do? AM I missing something? Thanks in advance and please help me. I wrote a lot of code but being very frustrated not being able to distribute it because of this.

It looks like you've got the external package in the same folder as your main package which uses it. In go, all packages must be in separate directories. It looks like the github project itself is actually doing that. If you separate the packages into different directories it should work properly.
