我的安裝GO1.13.6版本指南手冊之搭建環境

因好奇而走進go語言，讓你不在只聞其聲，不見其形。

https://golang.org/doc/install；這裏是go語言的官網文檔。吃不透英文，終究會被限制在有限的區域，一詞詞的吃透。

安裝包下載地址爲：https://golang.org/dl/。

若是打不開能夠使用這個地址：https://golang.google.cn/dl/。https://golang.google.cn/doc/install。

想了想，具體步驟就不提了，英文內容夠全了。

說一下關於SettingGOPATH的中外差異：

就像原文所說，「 If no GOPATH is set, it is assumed to be $HOME/go on Unix systems and %USERPROFILE%\go on Windows.」

那麼這個GOPATH竟然是在環境變量的用戶變量中；

那麼，原文中：

Your workspace can be located wherever you like, but we'll use C:\go-work in this example.

NOTE: GOPATH must not be the same path as your Go installation.

• Create folder at C:\go-work.
• Right click on "Start" and click on "Control Panel". Select "System and Security", then click on "System".
• From the menu on the left, select the "Advanced systems settings".
• Click the "Environment Variables" button at the bottom.
• Click "New" from the "User variables" section.
• Type GOPATH into the "Variable name" field.
• Type C:\go-work into the "Variable value" field.
• Click OK.

這段就是說將GOPATH這個環境變量的值由原來的%USERPROFILE%\go替換爲你的go工做空間的目錄。保存環境變量更改後，記得重啓電腦是其生效（win10）。

原文中是這樣使test.go生效的並測試的：

Check that Go is installed correctly by setting up a workspace and building a simple program, as follows.

Create your workspace directory, %USERPROFILE%\go. (If you'd like to use a different directory, you will need to set the GOPATH environment variable.)

Next, make the directory src\hello inside your workspace, and in that directory create a file named hello.go that looks like:

package main

import "fmt"

func main() {
	fmt.Printf("hello, world\n")
}

Then build it with the go tool:

C:\> cd %USERPROFILE%\go\src\hello
C:\Users\Gopher\go\src\hello> go build

The command above will build an executable named hello.exe in the directory alongside your source code. Execute it to see the greeting:

C:\Users\Gopher\go\src\hello> hello
hello, world

If you see the "hello, world" message then your Go installation is working.

You can run go install to install the binary into your workspace's bin directory or go clean -i to remove it.

Before rushing off to write Go code please read the How to Write Go Code document, which describes some essential concepts about using the Go tools.

可是，按舊有方式，還可在終端執行：go run hello.go

 

 使用原文中的生成hello.exe文件得使用當前目錄相對路徑執行hello.exe這種方式。

 

更新：

1. 由於go version >= 1.13，因此go env -w GO111MODULE=on修改相應依賴模式，go env查看
