Golang is an efficient programming language that is widely used to build various types of web applications and services. Due to its high performance and concise syntax, more and more programmers are using Golang as their language of choice. However, sometimes we may need to reinstall Golang to solve some problems or update to the latest version. In this article, we will discuss how to reinstall Golang.

Why we need to reinstall Golang

Before we start, we need to understand why we need to reinstall Golang. Here are some reasons:

  1. You may have encountered some issues related to Golang installation and configuration. This may cause your application to not function properly or cause various errors.
  2. You want to update Golang to the latest version to take advantage of new features and fix known vulnerabilities.
  3. There are situations where you want to uninstall Golang, for example, if you want to completely remove it from your computer.

Now that we understand why we need to reinstall Golang, let’s see how to perform this process.

Step 1: Uninstall the old version of Golang

If you have an old version of Golang installed, then you will need to uninstall it first. On Windows, you can uninstall Golang using the Control Panel's program uninstall feature. On Linux and Mac, you can uninstall Golang using a terminal command similar to the following:

$ sudo rm -rf /usr/local/go

This will delete all files and folders under the Go installation directory.

Step 2: Download the new Golang

Before you proceed to the next step, you need to download the latest version of Golang. You can find the download link on the official Golang website. After downloading the Golang installation package, you need to unzip it. On Linux and Mac, you can use the following command to unpack the .tar.gz file:

$ tar -xzvf go1.14.1.linux-amd64.tar.gz

This will create a directory called go in the current directory and copy all Golang files into that directory . If you are using a Windows operating system, you can double-click the installer to install it.

Step 3: Configure environment variables

Once you have downloaded and installed Golang, the next step is to configure environment variables. You need to add the path to Golang to the PATH system environment variable to be able to access it on the terminal. On Linux and Mac, you need to add the following code to your terminal configuration file (such as ~/.bashrc):

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

On Windows, you need to add the path of Golang to the PATH system environment in variables.

Step 4: Check if the installation is successful

Now you can check if Golang has been successfully installed by running the following command:

$ go version

If this command returns the Golang version number, That means you have installed Golang and can start using it.

Summary

In this article, we have discussed the process of Golang reinstallation. We explain why you need to reinstall Golang and provide some simple steps to uninstall the old version of Golang, download the new Golang, configure environment variables and check whether the installation was successful. Now you are ready to start using the latest version of Golang.
