出现错误“无法下载，$ GOPATH未设置”，但我有它 [英] Got error "cannot download, $GOPATH not set," yet I have it set

问题描述

然而，当我已经设置它。我甚至创建了子目录，我不知道是否需要：

  $ echo $ GOPATH&& ls -r $ GOPATH 
 /home/cyrus/.go 
 src pkg bin 
 
 $ echo $ GOROOT&& ls $ GOROOT 
 / usr / local / go 
 api作者bin贡献者doc favicon.ico include lib LICENSE misc PATENTS pkg README robots.txt src test VERSION 
  

为什么我在执行操作时仍然遇到错误：

  $ go获取code.google.com/p/go-tour/gotour 
包code.google.com/p/go-tour/gotour：无法下载，未设置$ GOPATH。有关详细信息，请参阅：go help gopath 
  

解决方案

一个像这样的变量：

  GOPATH = $ HOME / go 
  

它不会被导出到任何子流程。它只适用于该过程。如果您想将其导出到子流程，请使用 export ：

 导出GOPATH 
  

您也可以合并赋值和导出：

  export GOPATH = $ HOME / go 
  

However when I have already set it. I've even created sub directories which I don't know if necesary:

$ echo $GOPATH && ls -r $GOPATH
/home/cyrus/.go
src  pkg  bin

$ echo $GOROOT && ls $GOROOT
/usr/local/go
api  AUTHORS  bin  CONTRIBUTORS  doc  favicon.ico  include  lib  LICENSE  misc  PATENTS  pkg  README  robots.txt  src  test  VERSION

Why do I still get the error when I do:

$ go get code.google.com/p/go-tour/gotour                                                                                                               
package code.google.com/p/go-tour/gotour: cannot download, $GOPATH not set. For more details see: go help gopath

解决方案

If you set a variable like this:

GOPATH=$HOME/go

It won't be exported to any subprocesses. It's only available to that process. If you want to export it to subprocesses, use export:

export GOPATH

You can also combine the assignment and export:

export GOPATH=$HOME/go
