Import local folder of Golang code

Question

I have an 'example.go' file where I'm trying to import a directory in the same folder.

I have 'example.go' and the 'lucky' dir in the same folder called 'project'.

Here's how I'm trying to import the 'lucky' dir:

import (
    "fmt"
    golucky "goLucky"
    "io/ioutil"
    "os"
)

But when I run example.go, it looks like it is trying to import it from the go source because it throws the error:

    cannot find package "goLucky" in any of:
    /usr/local/go/src/pkg/goLucky (from $GOROOT)
    ($GOPATH not set)

How can I import the local folder in the same dir as the file?

@chengbo what if I want to import an online dir. like github.com/philipsoutham/golucky/v0.0.1, how can I do that? — gomangomango

set your GOPATH, and then go get github.com/xxxxx, import github.com/xxx/yyy see golang.org/doc/code.html#remote — chengbo

export GOPATH=/path/to/go, see golang.org/doc/code.html#GOPATH — chengbo

@chengbo Thank you. I made the directory look how it is supposed to. But when I Run $ GoPath = /Projects/dirName/, I get -bash: GOPATH: command not found — gomangomango

You need to set your GOPATH environment variable and locate your lucky dir within that. See http://golang.org/doc/code.html#Organization

So for example, if you set GOPATH=~, then put your lucky.go file in ~/src/lucky/lucky.go then you should be able to import "lucky" successfully.

what do I type in my .go file to set the GoPath?

Evan Over a year ago

GOPATH is an environment variable and is not set in your .go file, it is set in your shell or system settings.

Oh, okay. I made the directory look how it is supposed to. But when I Run $ GoPath = /Projects/dirName/, I get -bash: GOPATH: command not found

Please read the documentation I've already linked. As indicated both in the wikipedia article and the Go documentation, you must run export GOPATH=... in order to set its value in bash (other shells may be different).
