我试图像这样安装doozer:

$ goinstall github.com/ha/doozer

我得到这些错误。

不建议使用GOPATH和GOROOT配置。

您可以使用GO模块。

例如:

mkdir go_app
cd go_app
go mod init go_app

其他回答

值应该是(MACOS):

GOROOT="/usr/local/go" --> all binaries file core go
GOPATH="/Applications/proyectos/go" --> the route to workspace (custom workspace)

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.

(更新版的克里斯·邦奇的回答。)

对于所有新手,如果你正在使用Ubuntu,他们可以简单地导出GOPATH=$HOME/go,或者去帮助GOPATH获取更多信息。

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。
