我试图像这样安装doozer:

$ goinstall github.com/ha/doozer

我得到这些错误。

截至2020年和Go版本1.13+,在Windows中更新GOPATH的最佳方法是在命令提示符中输入:

setx GOPATH C:\mynewgopath

其他回答

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.

截至2020年和Go版本1.13+,在Windows中更新GOPATH的最佳方法是在命令提示符中输入:

setx GOPATH C:\mynewgopath

你可以使用一个命令:go env 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。

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
