本文解答了一位开发者在使用Go语言时遇到的问题：在正确设置了GOPATH的情况下，尝试运行一个包含本地包依赖的程序时遇到了找不到包的错误。通过检查发现，问题在于路径设置中的拼写错误。

go run footer.go 的时候呢， go会依次去GOPATH 和GOROOT设置的对应路径下面找对应的包（目录和文件）

找的时候呢，会在GoPATH 和GOROOT对应的目录后面再加一层路径 "/src/"哦

I have a sample project setup based on this article.

This is my directory structure:

goloang/
└── fooproject    └── src    ├── foo    │   └── foo.go    └── fooer    └── fooer.go

I have set the GOTPATH

$ echo $GOPATH
/Users/Bharat/Dev/golang/fooproject

I am trying to run foor.go but I get a cannot find package error even though it exists in the location referenced by GOPATH i.e. in src/foo.

This is how I am running it:

$ pwd
/Users/Bharat/Dev/goloang/fooproject/src/fooer $ go run fooer.go fooer.go:4:3: cannot find package "foo" in any of: /usr/local/go/src/foo (from $GOROOT) /Users/Bharat/Dev/golang/fooproject/src/foo (from $GOPATH)

These are the file contents.

src/foo/foo.go:

package foo

import ( "fmt" ) func Bar() { fmt.Println("bar") }

src/fooer/fooer.go:

package main

import ( "foo" ) func main() { foo.Bar() }

I get the same error when I try to do go build fooer.go.

Where am I going wrong with the project structure?

That might be because of a typo:

goloang
instead of
golang

You have:

$ echo $GOPATH
/Users/Bharat/Dev/golang/fooproject ^^^^^^ $ pwd /Users/Bharat/Dev/goloang/fooproject/src/fooer ^^^^^^^

goloang doesn't look like the correct spelling. – VonC Aug 20 '15 at 6:04

Aah!! My eyes seem bad. It was really a stupid mistake. Another pair of eyes looking at it was helpful! It works now. – Bharat Aug 20 '15 at 6:06

@Bharat 11PM in SF... I understand ;) I've been there many times. – VonC Aug 20 '15 at 6:07
