Setting environment variables

Configure Goroot and Gopath:

Copy Code code as follows:

To create a Go folder under the directory: mkdir ~/go

The following items are placed in the. BASH_RC (or maybe. bash_profile or. ZSHRC)

Export path= $PATH: $GOROOT/bin

Download Pkg under Mac Double-click to install, super simple, default installation path:/usr/local/go

Copy Code code as follows:

SOURCE ~/.bash_profile

Now that the Golang installation is complete, let's experience the following:

Copy Code code as follows:

Go env
Go version

Run Result:

Copy Code code as follows:

Liuxinmingdemacbook-pro:gotest liuxinming$ Go env

Development tool Configuration (Sublime Text 2)

Sublime Text 2 Download Address: HTTP://WWW.SUBLIMETEXT.COM/2

After downloading, the installation can be done directly.

Sublime Text 2 can be used free of charge, just save the number of times to reach a certain number will be prompted to buy, click Cancel can continue to use, and the official registered version without any difference.

Start the Golang Journey

Command + Shift + P to open package control and enter go, carriage return (this will cause code hints)

Create a new Hello.go

Copy Code code as follows:

Package Main

Import "FMT"

Func Main () {
Fmt. Printf ("Hello, world\n")
}

For the prepared file, use the shortcut command + B to open the terminal of Sublime Text 2, and enter the Go Build (name) to compile it: "Note: I test, the direct shortcut is automatically compiled, do not need any input"

The problem is, the default installed sublime does not have a go build, so you need to create one yourself.

Add the Go language build for sublime Text2

Tools-> Build System-> New build System

Enter the following code:

Copy Code code as follows:

{
"cmd": ["/usr/local/go/bin/go", "Run", "$file"],
"File_regex": "^ (... *?):( [0-9]*]:? ([0-9]*) ",
"Working_dir": "${file_path}",
"Selector": "Source.go"
}

Then select the build file: Go

Then COMMAND + B will have the output.
