Golang environment construction

With the continuous development of programming technology, as a relatively new programming language, golang has great advantages in productivity and code performance, so it has attracted more and more attention from developers. However, if you want to use golang for development, you must first set up the environment. In this article, I will introduce to you how to set up a golang environment in different operating systems.

1. Golang environment construction under Windows system

1. Download the golang installation program

Go to the golang official website https://golang.org/dl /Download the latest version of golang installer. After the download is completed, double-click to run the installer to start installing golang.

2. Add the golang installation path to the environment variable

After the installation is completed, you need to add the golang installation path to the environment variable so that you can run the golang command in the command line window . In the Windows 10 system, open the Control Panel, select "System and Security" --> "System" --> "Advanced System Settings", select "Environment Variables", find the "Path" variable in the system variables, and add golang The installation path is sufficient.

3. Advanced environment variable settings

In the current user variables and system variables, create new GOROOT and GOPATH variables, where GOROOT is the installation path of golang and GOPATH is the working directory .

4. Test the installation process

Enter the "go version" command in the command line window. If the golang version number is correctly output, it means that the golang environment is installed successfully.

2. Golang environment construction under Linux system

1. Download the tar.gz file of golang

On the golang official website https://golang.org /dl/Download the tar.gz file of the latest version of golang. After the download is complete, unzip the file to the /usr/local directory.

2. Modify the .bashrc file

Open the .bashrc file and add the following command:

export GOROOT=/usr/local/go
export GOPATH=$HOME/workspace/go
export PATH=$GOPATH/bin:$GOROOT/bin:$PATH

Here set goroot to the decompression path of golang and gopath to us The path to save the code.

3. Test the installation process

Enter the "go version" command in the command line window. If the golang version number is correctly output, it means that the golang environment is installed successfully.

3. Golang environment construction under MacOS system

1. Download the pkg file of golang

On the golang official website https://golang.org/dl /Download the pkg file of the latest version of golang. After the download is completed, double-click to run the pkg file to start installing golang.

2. Modify the .bash_profile file

Open the .bash_profile file and add the following command:

export GOROOT=/usr/local/go
export GOPATH=$HOME/workspace/go
export PATH=$GOPATH/bin:$GOROOT/bin:$PATH

Here set goroot to the installation path of golang and gopath to us The path to save the code.

3. Test the installation process

Enter the "go version" command in the command line window. If the golang version number is correctly output, it means that the golang environment is installed successfully.

Summary:

The above is the method of building golang environment in different operating systems. For beginners, they should first be familiar with the usage and development tools of golang, and then build the environment. In order to efficiently carry out code writing, testing and deployment work. I hope this article can be helpful to everyone, and welcome your valuable comments and suggestions.
