golang source package installation

Go language is a modern programming language that has significant advantages in development efficiency and execution efficiency. Therefore, more and more developers are starting to use Go language to write applications. Before using Go language for development, you need to set up the Go language environment first. Among them, the most important thing is to install the Go language compiler. This article will introduce how to correctly install the Go language source code package on Windows, Linux and macOS systems.

1. Download the Go language source code package

Before installing the Go language, we need to download the Go language source code package from the official website. Open the official Go language website (https://golang.org) and find the Downloads page. At the bottom of the page, you can see the download link for the source code package of the Go language.

Download address: https://golang.org/dl/

During the download, you need to select the version corresponding to your computer system. Here, we will introduce the installation method on Windows, Linux and macOS systems.

2. Install Go language on Windows system

Installing Go language on Windows system is relatively simple. You only need to download the msi file and then follow the steps.

1. Find the downloaded Go language installation package and double-click to run it.

2. In the installation wizard, click "Next".

3. Read the license agreement, click "Agree" if you agree, and then click "Next".

4. In the installation location interface, you can select the installation location. It is recommended to use the default location here and click "Next" directly.

5. Select the Start menu folder, or you can use the default, and then click "Next".

6. Click the "Install" button. The installation process will take place on your computer.

7. On the last interface, click "Finish".

8. Open the command prompt and enter "go version". If something like "go version go1.13.7 windows/amd64" appears, it means that the Go language has been successfully installed.

3. Installing Go language on Linux system

Installing Go language on Linux system is relatively more complicated and requires manual installation.

1. Find the downloaded Go language installation package, use the following commands to download and decompress (take go1.13.7 version as an example):

wget https://dl.google.com/go/go1.13.7.linux-amd64.tar.gz

sudo tar -C /usr/local -xzf go1.13.7.linux-amd64.tar.gz

2. Configure environment variables

• Use the following command to open the bashrc configuration file

sudo nano ~/.bashrc

• Add the following path to the last line of the file (the file may not exist and needs to be created)

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

Among them, GOPATH is the path to specify the go compiler package, which can be specified according to specific circumstances.

• Save the configuration file and refresh the local environment to make the changes take effect

source ~/.bashrc

3. Check whether the Go language is installed successfully

go version

If If words such as "go version go1.13.7 linux/amd64" are returned, the installation is successful.

4. Installing Go language on macOS system

Installing Go language on macOS system also requires manual installation.

1. Find the downloaded Go language installation package, use the following commands to download and decompress (take go1.13.7 version as an example):

curl -LO https://dl.google.com/go/go1.13.7.darwin-amd64.pkg

sudo installer -pkg go1.13.7.darwin-amd64.pkg -target /

2. Configure environment variables

Use the following command to open the bash_profile configuration file

sudo nano ~/.bash_profile

Add the following path to the last line of the file (the file may not exist and needs to be created)

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

Among them, GOPATH is the path that specifies the go compiler package and can be specified according to specific circumstances.

Save the configuration file and refresh the local environment to make the changes take effect

source ~/.bash_profile

3. Check whether the Go language is installed successfully

go version

If it returns "go version go1. 13.7 darwin/amd64", the installation is successful.

Summary:

Install go on Windows, Linux and macOS systems. Although the installation methods are slightly different, you can install them by downloading the installation package and configuring environment variables. It is recommended that developers follow the official recommended installation methods to avoid problems when using or developing golang applications.
