解决方案

GOPATH 会被讨论在 cmd / go 文档中：

GOPATH 环境变量列出了查找Go代码的位置。在
Unix上，该值是冒号分隔的字符串。在Windows上，值为
分号分隔的字符串。在计划9中，该值是一个列表。

GOPATH 必须设置为在外部获取，构建和安装包
标准Go树

GOROOT 安装说明：

Go二进制发行版假设它们将安装在
/ usr / local / go （或 c：\ Go 在Windows下），但可以将
Go工具安装到其他位置。在这种情况下，您必须将
GOROOT 环境变量设置为指向安装
的目录。

例如，如果您安装了Go到您的主目录，您应该将
以下命令添加到 $ HOME / .profile ： p>

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





GOROOT 安装到自定义位置。

解决方案

GOPATH is discussed in the cmd/go documentation:

The GOPATH environment variable lists places to look for Go code. On Unix, the value is a colon-separated string. On Windows, the value is a semicolon-separated string. On Plan 9, the value is a list.

GOPATH must be set to get, build and install packages outside the standard Go tree.

GOROOT is discussed in the installation instructions:

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.
