golang 的GOPATH设置的问题

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
