Go language is a rapidly developing programming language. Through continuous updates and improvements, its functions become more powerful. When new versions are released, upgrading is the best way to ensure your applications and code stay up to date and most secure. Well, in this article, we will explore how to upgrade the Go language.
Before we delve into how to upgrade the Go language, it is first necessary to understand the number of Go language versions and the differences between them. Versions of the Go language include:
Therefore, we can conclude that upgrading the Go language means upgrading to the next minor or patched version of Go, that is, updating from Go 1.13 to Go 1.14.
Based on understanding the Go language version, let’s take a look at the steps on how to upgrade the Go language.
Before upgrading the Go language, it is best to back up your code first. This is very important as incorrect operation may cause code to be lost or changed. Please make sure that the backup is returned intact so that the original code can be restored if any errors occur.
Download the latest version of the Go language. You can download the Go language installer from the official website (https://golang.org/dl/) and choose the version compatible with your operating system.
After installing the new Go version, you need to update your computer environment variables. You can check the current version by running the following command in the terminal:
go version
If the version has been updated, update the environment variables to reflect the new version update. You can update environment variables as follows:
export GOROOT=/usr/local/go export GOPATH=$HOME/go export PATH=$GOPATH/bin:$GOROOT/bin:$PATH
After completing the update of the environment variables, use the following command to compile your application and test whether it runs normally under the new version:
go build
go test
If your application does not run properly under the new version, please Check the code and dependencies to find the problem.
When you confirm that the new version of the Go language can run your application smoothly, you need to delete the old version. You can uninstall it using the command line or in the control panel.
The method for uninstalling the Go language can vary by operating system, but generally includes:
sudo rm -rf /usr/local/go

~/.bashrc
Path to any old versions of the Go language added in the file. Through this article, we have learned how to upgrade the Go language and understood the main steps. Upgrading the Go language is one of the best ways to keep your code and applications up to date and most secure.
