A brief analysis of how to build a golang environment under Win and Linux

Golang is a programming language developed by Google. Due to its high efficiency, concurrency, simplicity and other characteristics, it is favored by more and more developers. Before developing Golang, we need to set up the Golang environment first. This article will introduce in detail how to build a Golang environment on Windows and Linux operating systems.

1. Golang construction in Windows environment

1. Download Golang

First, we need to download the Golang installation program. You can find the latest version of the Golang installer on the download page of the Golang official website https://golang.google.cn/dl/, and select the Windows platform version to download.

2. Install Golang

After the download is completed, run the downloaded installation program directly and follow the prompts to complete the installation.

3. Configure environment variables

After completing the installation, you need to configure the environment variables. The specific steps are as follows:

• ① First, right-click "Computer" and select "Properties".

• ② Click "Modify Settings" to open the "System Properties" window.

• ③ In the "System Properties" window, select the "Advanced" tab and click the "Environment Variables" button.

• ④ In the "Environment Variables" dialog box, find and select the "Path" variable, and click the "Edit" button.

• ⑤ In the pop-up editing dialog box, add the installation path of Golang, for example: C:\Go\bin, and then click the "OK" button.

• ⑥ Set GOPATH (Golang’s working path) to your own working directory, for example: C:\Users\YourUserName\go.

4. Test Golang environment

After completing the configuration of environment variables, open the command prompt (CMD) and enter "go version". If it works If the Golang version number is correctly output, it means that the Golang environment has been successfully built.

2. Golang construction in Linux environment

1. Download Golang

Similarly, in Linux environment, we need First download the Golang installer. You can find the latest version of the Golang installer on the download page of the Golang official website https://golang.google.cn/dl/, and select the version suitable for the Linux platform to download.

2. Install Golang

After the download is complete, unzip the downloaded installation program, then open the terminal window (Terminal) and enter the following command:

$ sudo tar -C /usr/local -xzf go1.17.linux-amd64.tar.gz

3. Build environment variables

After completing the installation of Golang, we need to configure environment variables. The specific steps are as follows:

• ① Enter the following command in the terminal window:

$ nano ~/.bashrc

• ② In the open file , add the following content:

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

Among them, "$HOME/go" is the working path of Golang, which can be modified to other paths according to personal preferences.

• ③ Press the Ctrl X key to exit the edit mode, then enter "Y" to save the changes, and finally press the Enter key to exit.

• ④ Then enter the following command to make the environment variables take effect:

$ source ~/.bashrc

4. Test Golang environment

After completing the configuration of the environment variables, open a terminal window and enter "go version". If the Golang version number can be correctly output, it means that the Golang environment has been set up successfully.

Summary

The above are the steps for setting up the Golang environment in Windows and Linux environments. During the construction process, you can set GOPATH and other related variables according to your own habits. It is recommended that after setting up, you first conduct a simple test to ensure that the Golang environment is running normally.
