Golang is an efficient programming language with fast compilation speed and good concurrency performance. However, when using Golang, we often need to upgrade the version to get better experience and functionality.

In this article, we will discuss how to upgrade Golang and what you need to pay attention to when upgrading.

1. Golang version upgrade method

Use the official download and installation package

Golang official website (https://golang.org/dl/) Various versions of Golang are provided for download and installation. We only need to download the corresponding installation package and then run the installation.

Use the operating system package manager

Many Linux distributions (such as Ubuntu, Debian, etc.) or MacOS provide a way to upgrade Golang through the package manager . If you are using these operating systems, then simply upgrade using the package manager provided by your operating system.

For example, if you are using Ubuntu, you can use the following command to upgrade Golang:

sudo apt-get update

sudo apt-get install golang

Using GVM

GVM is a Golang version management tool that allows us to easily install and manage multiple Golang versions. Using GVM you can easily switch between different Golang versions, and you can also easily install and upgrade Golang.

Install GVM as follows:

bash

After installing GVM, you can use the following command to install a new Golang version:

gvm install go_version

Where go_version is the Golang version number to be installed, for example gvm install go1.13.

2. Upgrade Notes

Backup Work

Before upgrading Golang, you should back up all related files and directories, especially important projects and configuration files. This prevents data loss or damage during the upgrade process.

Check code compatibility

Before upgrading to a new version of Golang, we need to ensure the compatibility of the code. When Golang updates its version, it may introduce new language changes or remove certain functions from the standard library, which may cause problems in the code. Before upgrading, we need to ensure that the code is supported by the new version of Golang.

Compile projects

After the upgrade is completed, we need to recompile all Golang projects to ensure that they can run normally. If compilation errors occur, it may be because we forgot to adjust the versions of some dependent packages or libraries. Therefore, after upgrading, you need to check the project dependencies to confirm that they are all the correct versions.

Understand the changes in the new version

Before upgrading to the new version of Golang, we need to understand the changes and new features of the new version. By understanding the changes in the latest version of Golang, we can plan and prepare for new features. At the same time, we also need to know the limitations, limitations and other impacts of the new version of Golang.

3. Summary

In this article, we discussed the upgrade method of Golang and what needs to be paid attention to when upgrading. Upgrading the Golang version is a key step for us to get better features and experience, so we need to follow the above methods to ensure a smooth upgrade. At the same time, we also need to consider the impact and changes caused by this upgrade on a more comprehensive level.

Finally, we hope that through this article, you can gain a better experience using Golang and improve development efficiency and code quality.
