GOPATH和GOROOT的值应该是什么?

我试图像这样安装doozer:

$ goinstall github.com/ha/doozer

我得到这些错误。

goinstall: os: go/build: package could not be found locally goinstall: fmt: go/build: package could not be found locally goinstall: io: go/build: package could not be found locally goinstall: reflect: go/build: package could not be found locally goinstall: math: go/build: package could not be found locally goinstall: rand: go/build: package could not be found locally goinstall: url: go/build: package could not be found locally goinstall: net: go/build: package could not be found locally goinstall: sync: go/build: package could not be found locally goinstall: runtime: go/build: package could not be found locally goinstall: strings: go/build: package could not be found locally goinstall: sort: go/build: package could not be found locally goinstall: strconv: go/build: package could not be found locally goinstall: bytes: go/build: package could not be found locally goinstall: log: go/build: package could not be found locally goinstall: encoding/binary: go/build: package could not be found locally

以下是我的简单设置:

directory for go related things: ~/programming/go
directory for go compiler/tools: ~/programming/go/go-1.4
directory for go software      : ~/programming/go/packages

GOROOT、GOPATH、PATH的设置如下:

export GOROOT=/home/user/programming/go/go-1.4
export GOPATH=/home/user/programming/go/packages
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin

所以，简而言之:

GOROOT是编译器/工具，来自go安装。 GOPATH是为你自己的项目/第三方库(下载“go get”)。

GOPATH的讨论如下:

GOPATH环境变量 GOPATH可以设置为一个以冒号分隔的路径列表，其中Go 可以找到代码、包对象和可执行文件。设置GOPATH使用goinstall来构建和安装您自己的代码和 Go树之外的外部库(并避免写入 makefile)。

这里讨论的是GOROOT:

$GOROOT Go树的根，通常是$HOME/ Go。默认为目录的父目录。Bash运行。如果你选择不去的话设置$GOROOT时，必须运行gomake而不是make或gmake 使用传统的makefile开发Go程序。

GOPATH不应该指向Go安装，而是指向您的工作空间(参见https://golang.org/doc/code.html#GOPATH)。当你使用go get或go install安装某个包时，它会落在GOPATH中。这就是为什么它警告你，你绝对不希望从互联网随机包被转储到你的正式安装。

在cmd/go文档中讨论了GOPATH:

GOPATH环境变量列出了寻找Go代码的位置。在 Unix，值是一个冒号分隔的字符串。Windows操作系统为以分号分隔的字符串。在Plan 9中，取值为列表。必须将GOPATH设置为在外部获取、构建和安装包标准围棋树。

安装说明中讨论了GOROOT:

The Go binary distributions assume they will be installed in /usr/local/go (or c:\Go under Windows), but it is possible to install the Go tools to a different location. In this case you must set the GOROOT environment variable to point to the directory in which it was installed. For example, if you installed Go to your home directory you should add the following commands to $HOME/.profile: export GOROOT=$HOME/go export PATH=$PATH:$GOROOT/bin Note: GOROOT must be set only when installing to a custom location.

我读了go help gopath文档，仍然非常困惑，但从另一个go文档页面中发现了这个小块:

GOPATH环境变量指定工作空间的位置。它可能是开发Go代码时需要设置的唯一环境变量。
