Golang: Błąd katalogu instalacyjnego?

Question

mam błąd:

go install: no install location for directory /Users/xwilly/Dropbox/go/project/src outside GOPATH 

używam odchodzenie w wersji 1.1 na OS X.

mogę zbudować & uciekać, ale nie można zainstalować pakiety.

Moja okolica:

GOPATH=/Users/xwilly/Dropbox/go/project 
PATH=/Library/Frameworks/Python.framework/Versions/2.7/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/go/bin:/Users/xwilly/Dropbox/go/project/bin 

drzewo projektu:

/Users/xwilly/Dropbox/go/project 
bin 
pkg 
src 

mogę budować bez błędów:

..:src xwilly$ go build test.go 
..:src xwilly$ go install test.go 
go install: no install location for directory /Users/xwilly/Dropbox/go/project/src outside GOPATH 

Oto prosty przykład:

xwilly$ cat test.go 
package main 

import (
    "fmt" 
) 

func main() { 
    fmt.Println("Bonjour") 
} 
xwilly$ go run test.go 
Bonjour 
xwilly$ go install test.go 
go install: no install location for directory /Users/xwilly/Dropbox/go/project/src/learning outside GOPATH 

Answer 1

Command go

GOPATH environment variable

Each directory listed in GOPATH must have a prescribed structure:

The src/ directory holds source code. The path below ' src ' determines the import path or executable name.

The pkg/ directory holds installed package objects. As in the Go tree, each target operating system and architecture pair has its own subdirectory of pkg (pkg/GOOS_GOARCH).

If DIR is a directory listed in the GOPATH , a package with source in DIR/src/foo/bar can be imported as " foo/bar " and has its compiled form installed to " DIR/pkg/GOOS_GOARCH/foo/bar.a ".

The bin/ directory holds compiled commands. Each command is named for its source directory, but only the final element, not the entire path. That is, the command with source in DIR/src/foo/quux is installed into DIR/bin/quux, not DIR/bin/foo/quux . The foo/ is stripped so that you can add DIR/bin to your PATH to get at the installed commands. If the GOBIN environment variable is set, commands are installed to the directory it names instead of DIR/bin .

Here's an example directory layout:

GOPATH=/home/user/gocode 

/home/user/gocode/ 
    src/ 
     foo/ 
      bar/    (go code in package bar) 
       x.go 
      quux/    (go code in package main) 
       y.go 
    bin/ 
     quux     (installed command) 
    pkg/ 
     linux_amd64/ 
      foo/ 
       bar.a   (installed package object) 

Twoja struktura katalogów jest nieprawidłowa. Próbujesz zainstalować polecenie (package main). Powinien znajdować się w katalogu źródłowym nazwanym po twoim poleceniu. Zobacz powyższe polecenie quux.

W twoim przypadku, załóżmy, że twoje polecenie zostanie nazwane billy.

$ mkdir -p /Users/xwilly/Dropbox/go/project/src/billy 

który jest w Twoim GOPATH. Przenieś swój plik test.go do tego katalogu. Uruchom

$ go install billy 

Polecenie billy powinno, chyba że ustawione GOBIN być instalowany w katalogu

/Users/xwilly/Dropbox/go/project/bin 

wewnątrz GOPATH, który powinien być w swoim PATH.
