How to install Golang under macOS system and set its installation path

Go language (Golang) is a programming language developed by Google. Its advantages include simplicity, efficiency, good concurrency processing, and cross-platform support. This article will introduce how to install Golang under macOS system and set its installation path.

Installation process

1. Go to the Golang official website https://golang.org/dl/ to download the installation package corresponding to the macOS system, as shown in the figure:

2. Double-click the installation package and follow the prompts to complete the installation, as shown in the figure:

3. After the installation is completed, we can open the terminal ( Terminal) and enter the following command to check whether Golang is installed successfully:

$ go version

If the following information appears, Golang has been installed successfully:

Set the installation path

By default, Golang will be installed in the /usr/local/go path. However, if we want to install it to another path, we need to configure it as follows:

1. Create a new directory in the terminal, for example:

$ sudo mkdir /mynewpath

2. Set the permissions of the directory :

$ sudo chown $USER /mynewpath

This will make the directory readable and writable by the current user.

3. Open the environment variable file

$ vi ~/.bash_profile

If there is no such file, you can use the command to create a new one:

$ touch ~/.bash_profile

4. Add the following command to the end of the file:

export GOPATH=/mynewpath
export PATH=$PATH:$GOPATH/bin

Among them, GOPATH represents the installation path of Golang, and PATH is used to specify the search path of the command. Press the "i" key to enter the editing mode and enter these commands to edit.

5. Press the "esc" key to exit the edit mode and enter ":wq" to save and close the file.

6. Execute the following command to make the configuration file take effect:

$ source ~/.bash_profile

7. Finally, we can enter the following command to see if GOPATH is successfully set:

$ echo $GOPATH

Among them, The echo command is used to output variable values. If the variable is set successfully, the terminal will output the set path value.
