Golang：安装目录错误？ [英] Golang: Installation directory error?

问题描述

我有错误：

  go install：no安装目录位置/ Users / xwilly / Dropbox / go / project / src outside GOPATH 
  

我在OS X上使用版本1.1。

我可以建立&

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安装test.go 
 go install：没有安装目录/ Users / xwilly / Dropbox / go / project / src在GOPATH之外的位置
  

这里是一个简单的例子：

  xwilly $ cat test.go 
 package main 
 
 import（ 
fmt
）
 
 func main（）{
 fmt.Println（Bonjour）
} 
 xwilly $ go run test.go 
 Bonjour 
 xwilly $ go安装测试。去
去安装：没有安装目录的位置/ Users / xwilly / Dropbox / go / project / src / learning GOPATH 
  

解决方案

命令行

GOPATH环境变量

在 GOPATH 中列出的每个目录都必须有一个规定的结构：

src / 目录保存源代码。 ' src '下的路径决定了
的导入路径或可执行文件名称。

pkg / 目录保存安装的软件包对象。和Go树一样，每个目标操作系统和架构对的
都有它自己的
子目录 pkg （ pkg / GOOS_GOARCH ）。

如果 DIR 是 GOPATH ，一个包含
DIR / src / foo / bar源文件的包可以导入为 foo / bar ，它的编译形式
被安装到 DIR / pkg / GOOS_GOARCH / foo / bar.a 。

bin / 目录保存已编译的命令。每个命令都以
的源目录命名，但只有最后一个元素，而不是整个路径。
也就是说，源代码位于 DIR / src / foo / quux 中的命令被安装到
DIR / bin / quux中，而不是 DIR /斌/富/ QUUX 。 foo / 被剥离，因此您
可以将 DIR / bin 添加到 PATH 来获取已安装的命令。如果设置了
GOBIN 环境变量，则将命令安装到它所指定的
目录，而不是 DIR / bin < code $。



以下是一个目录布局示例：



  GOPATH = / home / user / gocode 
 
 / home / user / gocode / 
 src / 
 foo / 
 bar /（在软件包栏中输入代码）
 x.go 
 quux /（在主包中去代码）
 y.go 
 bin / 
 quux（已安装的命令）
 pkg / 
 linux_amd64 / 
 foo / 
 bar.a（安装的包对象）
  




您的目录结构错误。您正试图安装一个命令（ package main ）。它应该位于以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 
  

它位于 GOPATH 。将 test.go 文件移动到此目录。运行

  $ go安装billy 
  

命令 billy 应该被安装在中，除非你已经设置 GOBIN / p>

  / Users / xwilly / Dropbox / go / project / bin 
   GOPATH 内的$ p> 
 
 
目录，该目录应位于 PATH 。
 
I have the error:
go install: no install location for directory /Users/xwilly/Dropbox/go/project/src outside GOPATH 
I'm using go version 1.1 on OS X.

I can build & run but can't install packages.

My environment:
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
Project tree:
/Users/xwilly/Dropbox/go/project
bin
pkg
src
I can build without error:
..: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
Here is a simple example:
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

解决方案

  
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)

Your directory structure is wrong. You are trying to install a command (package main). It should be in a source directory named after your command. See the quux command above.

In your case, assume your command is going to be named billy.
$ mkdir -p /Users/xwilly/Dropbox/go/project/src/billy
which is inside your GOPATH. Move your test.go file to this directory. Run
$ go install billy
The command billy should, unless you have set GOBIN, be installed in the 
/Users/xwilly/Dropbox/go/project/bin
directory inside your GOPATH, which should be in your PATH.
