我试图像这样安装doozer:

$ goinstall github.com/ha/doozer

我得到这些错误。

在osx中,我安装了brew,下面是适合我的设置

GOPATH="$HOME/my_go_work_space" //make sure you have this folder created

GOROOT="/usr/local/Cellar/go/1.10/libexec"

其他回答

第一次运行go env。 如果你看到go没有安装,你可以通过homebrew或包和/或其他方式安装它。 如果您看到输出,那么您的Go已经安装。 它向你展示了所有已设置和未设置的env。

如果你看到GOROOT为空:

在我的电脑上:/usr/local/go/bin/go 然后export GOROOT=/usr/local/go

如果你看到GOPATH为空:

在计算机的任何位置为go项目创建任意目录,在我的例子中是:~/GO_PROJECTS 然后导出GOPATH=~/GO_PROJECTS

安装Go lang之后,GOROOT是安装的根目录。

当我在Windows C:\目录中分解Go Lang二进制时,我的GOROOT应该是C:\ Go。 如果安装Windows安装程序,它可能是C:\Program Files\go(或C:\Program Files (x86)\ go, 64位包)

 GOROOT = C:\go

而我的GOPATH是Go lang源代码或工作区的位置。

如果我的Go lang源代码位于C:\Users\\GO_Workspace,那么你的GOPATH将如下所示:

 GOPATH = C:\Users\<xyz>\GO_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.

如上所述:

GOPATH环境变量指定您的 工作区。

对于Windows,这对我来说是有效的(在Ms-dos窗口中):

set GOPATH=D:\my_folder_for_go_code\

这将创建一个Ms-dos识别的GOPATH变量,使用如下:

cd %GOPATH%

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。
