mac golang environment setup

In any programming language, environment construction is the most basic and important. When using Mac as a development environment, if you are learning or using Go language, then setting up a Go development environment on Mac has become a must-learn content.

In this article, I will introduce to you how to build a Golang development environment on Mac, so that you can easily start using Go programming.

1. Install command line tools

Mac OS X comes with a set of command line tools. You can quickly complete various tasks by running shell commands in Terminal. In most cases, these command line tools can meet our needs, but when programming in Golang, we also need to install additional command line tools.

To install the command line tool, first open the terminal and enter the following command in the terminal:

xcode-select --install

Follow the prompts to complete the installation of the command line tool.

2. Install Homebrew

Homebrew is a software package management tool for Mac OS X. It can easily install and manage various software packages for us. To install Homebrew, just enter the following command in the terminal:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Wait for Homebrew to be installed.

3. Installing Golang

Use Homebrew to install Golang. Just enter the following command in the terminal:

brew install go

Wait for Golang to be installed.

4. Configuring environment variables

After installing Golang, we need to perform some basic configurations. First, you need to configure environment variables so that Golang's command line tools can be accessed in the terminal.

Open the terminal and enter the following command:

cd ~
mkdir go
cd go
mkdir bin src pkg

This is to create a GOPATH directory to store our Go project and related files. Next, we need to configure the environment variable, open the terminal, and enter the following command:

echo "export GOPATH=$HOME/go" >> ~/.bash_profile
echo "export PATH=$PATH:$GOPATH/bin" >> ~/.bash_profile

This will add GOPATH to the environment variable. We need to reopen the terminal window for the configuration to take effect.

5. Testing Golang

Now we have successfully set up the Golang development environment on Mac. Next, we need to test whether our installation was successful.

Open the terminal and enter the following command in the terminal:

go version

If the Golang version number is output, it proves that our installation has been successful.

6. Developing with Golang

Now, we can start using Golang for development on Mac. We can use the commands provided in the terminal to create and run Golang projects, or we can use third-party IDEs such as Goland for development. Here, we recommend using Goland, which is a cross-platform IDE from JetBrains. It provides powerful editing, debugging and testing functions, which can greatly improve our development efficiency.

Before using Goland for development, we also need to make some basic settings. First, you need to open Goland, and then click "Preferences" in the menu bar to enter the settings interface. In the settings interface, find the "Go" option and click the "Go Path" tab. In the "Go Path" tab, you need to add the GOPATH directory we just created. Enter "$HOME/go" in the "Custom" input box.

Now, we have completed setting up the Golang environment on Mac. Whether you use command line tools or Goland, you can easily start developing with Golang.
