Golang : Installation directory error?

Question

我有错误:

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

我在 OS X 上使用 go 版本 1.1。

我可以构建和运行，但不能安装包。

我的环境:

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

项目树:

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

我可以毫无错误地构建:

..: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

这是一个简单的例子:

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

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)

您的目录结构错误。您正在尝试安装命令(package main)。它应该位于以您的命令命名的源目录中。请参阅上面的 quux 命令。

在您的情况下，假设您的命令将被命名为 billy。

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

在你的 GOPATH 中。将您的 test.go 文件移动到此目录。运行

$ go install billy

命令billy应该安装在

中，除非你设置了 GOBIN

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

你的 GOPATH 中的目录，它应该在你的 PATH 中。
