无法让Golang在Ubuntu中工作 [英] Can't get Golang to work in Ubuntu

问题描述

好的，所以我已经下载了Go 1.1并把它放到$ HOME / Documents / go中。

然后，我修改了我的 .bashrc 为：

  export GOPATH = $ HOME / Documents / go 
 export GOROOT = $ GOPATH 
 export GOARCH = amd64 
 export GOOS = linux 
 export GOBIN = $ GOPATH / bin 
 export PATH = $ PATH：$ GOBIN 
  

我已经找到了 .bashrc ，并试过：

  jan @ janpc：〜$ go版本
 go版本go1.1 linux / amd64 
  

但我无法得到它来编译或安装任何依赖项。
例如。我尝试运行我的小测试程序：

  jan @ janpc：〜/ Documents / go / src / github.com / jan / scrypt $ go run scrypt.go 
警告：GOPATH设置为GOROOT（/ home / jan / Documents / go）没有效果
 scrypt.go：9：3：找不到软件包github.com / dchest / scrypt：
 /home/jan/Documents/go/src/pkg/github.com/dchest/scrypt（from $ GOROOT）
（$ GOPATH未设置）
 jan @ janpc：〜/ Documents / go / src / github.com / jan / scrypt 
  

当我尝试安装依赖项时：

  jan @ janpc：〜/ Documents / go / src / github.com / jan / scrypt $ go获取github.com/dchest/scrypt
警告：GOPATH设置为GOROOT（/ home / jan / Documents / go）无效
包github.com/dchest/scrypt：无法下载，$ GOPATH不得设置为$ GOROOT。有关更多详细信息，请参阅：go help gopath 
  

它在Mac上编译并正常工作。我想不出什么毛病我的配置，如果我尝试删除 $ GOROOT 或 $ GOPATH 什么作品，我不知道还有什么将它们设置为，以外的其他路径进入

编辑：
没有$ GOROOT上设置我的苹果电脑。但是如果我在ubuntu上删除 $ GOROOT ，当我尝试编译时，会遇到类似这样的错误。

<$ p
/ usr / local / go / src / pkg / fmt（from $ GOROOT）
/ home / jan / Documents $ p $ 无法找到软件包fmt / go / src / fmt（from $ GOPATH）


解决方案

您设置的环境变量

  $ export GOROOT = $ GOPATH 
  

是一个错误。没有这样的设置要求或建议。实际上，它会削弱Go构建系统所看到的环境。

删除该设置，重新创建您的环境（ .bashrc ）或打开一个新的终端，它应该工作（如果没有其他问题存在）。

另外，如果你不交叉编译，我建议删除这些：

 出口GOARCH = amd64 
出口GOOS = linux 
  

简而言之，正确导出的GOPATH是真正需要的 only 环境变量。一些更多的提示这里

编辑：好的，所以我下载了二进制发行版（go1.1.linux-amd64.tar.gz）。从自述文引用：

二元分布备注

如果您刚刚解散了二进制Go分发版，则需要将
环境变量$ GOROOT设置为go
目录（包含此README的目录）的完整路径。如果将它解压缩到/ usr / local / go中，或者通过运行all.bash（请参阅doc / install.html）从源重新生成
，则可以省略
变量。
您还应该将Go二进制目录$ GOROOT / bin
添加到shell的路径中。例如，如果您将tar文件解压缩到$ HOME /去，你可能
将在.profile如下：

  export GOROOT = $ HOME / go 
 export PATH = $ PATH：$ GOROOT / bin 
  

有关更多详细信息，请参阅doc / install.html。

<从这一点来看，很明显，你必须没有遵循上述说明。解决这个问题，我希望它能为你工作。

Ok, So I've downloaded Go 1.1 and put it into $HOME/Documents/go.

Then, I've modified my .bashrc to be:

export GOPATH=$HOME/Documents/go                                                
export GOROOT=$GOPATH
export GOARCH=amd64
export GOOS=linux
export GOBIN=$GOPATH/bin
export PATH=$PATH:$GOBIN

Than I've sourced the .bashrc, and tried:

jan@janpc:~$ go version
go version go1.1 linux/amd64

But I can't get it to compile or install any dependencies. Eg. I try to run my little test program:

jan@janpc:~/Documents/go/src/github.com/jan/scrypt$ go run scrypt.go 
warning: GOPATH set to GOROOT (/home/jan/Documents/go) has no effect
scrypt.go:9:3: cannot find package "github.com/dchest/scrypt" in any of:
    /home/jan/Documents/go/src/pkg/github.com/dchest/scrypt (from $GOROOT)
    ($GOPATH not set)
jan@janpc:~/Documents/go/src/github.com/jan/scrypt$ 

And when I try to install dependencies:

jan@janpc:~/Documents/go/src/github.com/jan/scrypt$ go get "github.com/dchest/scrypt"
warning: GOPATH set to GOROOT (/home/jan/Documents/go) has no effect
package github.com/dchest/scrypt: cannot download, $GOPATH must not be set to $GOROOT. For more details see: go help gopath

It compiles and works fine on mac. I can't figure out whats wrong with my config, if I try to remove $GOROOT or $GOPATH nothing works, and I don't know what else to set them to, other than the path to Go.

EDIT: There is no $GOROOT set on my mac. But if I remove $GOROOT on ubuntu, I get bunch of errors like these when I try to compile.

cannot find package "fmt" in any of:
    /usr/local/go/src/pkg/fmt (from $GOROOT)
    /home/jan/Documents/go/src/fmt (from $GOPATH)

解决方案

Your enviroment variable you've set by

$ export GOROOT=$GOPATH

is a mistake. Nowhere is such setting required nor recommended. Actually, it cripples the environment seen by the Go build system.

Remove that setting, recreate your environment (. bashrc) or open a new terminal and it should work (if no other problems exists).

Additionally, if you're not cross compiling, I recommend to remove also these:

export GOARCH=amd64
export GOOS=linux

In short, proper exported GOPATH is the only environment variable which is, in the first approximation, really needed. Some more hints here.

EDIT: Okay, so I've downloaded the binary distribution (go1.1.linux-amd64.tar.gz). Quoting from README:

Binary Distribution Notes

If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this README). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install.html). You should also add the Go binary directory $GOROOT/bin to your shell's path.

For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile:

export GOROOT=$HOME/go
export PATH=$PATH:$GOROOT/bin

See doc/install.html for more details.

From this it's clear that you must have not followed properly the above instructions. Fix that and I hope it will work for you then.
