The specific steps are as follows:

1. Download the go language development package

Everyone You can download the Go language development package under Windows system from the Go language official website (https://golang.google.cn/dl/), as shown in the figure below.

Here we download the 64-bit development package. If the reader’s computer is a 32-bit system, you need to download the 32-bit development package, as shown in the picture above Scroll down on the page to find the download address of the 32-bit development package, as shown in the figure below.

Note: When downloading the Windows version of the Go language development package, try to choose the MSI format, because it can be installed directly into the system without additional operations.

3. Install the go language development package

Double-click the Go language development package we downloaded to start the installation program, as shown in the figure below. This is the user license agreement for the Go language. No need to worry about it. Just check "I accept..." and click "Next".

Under Windows systems, the Go language development package will be installed in the Go directory of the C drive by default. It is recommended to install it in this directory, which is more convenient to use. Of course, you can also choose other installation directories, and click "Next" after confirming that it is correct, as shown in the figure below:

There is no other installation method for the Go language development package. For the options that need to be set, click "Install" to start the installation, as shown in the following figure:

Wait for the program to complete the installation, and then click "Finish" to exit the installation program .

#After the installation is completed, some directories and files will be generated in the installation directory we set, as shown in the figure below:

The structure of this directory follows the GOPATH rules. This concept will be mentioned in the following chapters. The meaning of each folder in the directory is as shown in the following table.

#When developing, there is no need to pay attention to these directories. If readers want to understand the underlying principles in depth, they can continue to explore through the above introduction.

4. Set environment variables

After the development package is installed, we also need to configure the GOPATH environment variable before we can use the Go language for development. GOPATH is a path used to store code packages needed for development.

Right-click "This Computer" (or "My Computer") on the desktop or explorer → "Properties" → "Advanced System Settings" → "Environment Variables", as shown in the figure below.

Find the option corresponding to GOPATH in the pop-up menu and click Edit to modify it. If not, you can choose to create a new one and fill in the variable name as GOPATH and set the variable value. It can be any directory (try to choose an empty directory), such as D:\Go.

Tip: After filling in, you need to click "OK" in each open window to save the settings.

Other environment variables in the installation package will be automatically set. By default, Go will be installed in the directory c:\go, but if you modify the installation directory during the installation process, you may need to manually modify the values ​​of all environment variables.

After the environment variables are set, open the cmd window and enter the go env command to test.

Only part of the results are shown above. If results similar to the above appear after executing the go env command, it means that our Go development package has been installed successfully.
