Node.js is an open source, cross-platform JavaScript running environment. It uses the Google V8 engine to compile JavaScript code so that JavaScript can be run on the server side, thereby quickly processing a large number of concurrent requests. Since Node.js is open source and developing very quickly, a new version is released every few weeks with better performance and features. However, many beginners don't know how to upgrade Node.js to the latest version, so this article will introduce how to upgrade Node.js to the latest stable version.

1. Install nvm

The easiest way to upgrade Node.js is to use nvm, the full name is Node version manager. nvm makes it easy to install and manage multiple Node.js versions at any time, and switch versions easily. To upgrade Node.js, you first need to install nvm. nvm runs on various operating systems and can be downloaded from the official documentation and installed according to the instructions.

2. Query the available versions

After installing nvm, you can use the following command to view the available Node.js versions:

nvm ls-remote

This command will list all stable versions that can be installed version and development version. Among them, the stable version is the officially supported version, while the development version is the test version before each version is released. It is recommended to use the stable version.

3. Install the latest version

Now you can use the following command to install the latest stable version:

nvm install node --lts

Among them, --lts means to install only the latest stable version. Note that --lts only works with version managers on Linux and macOS systems.

4. Verify the installation

After the installation is complete, you can run the following command to verify the version of Node.js:

node -v

This command will output the installed Node.js version.

5. Upgrade existing version

If you have installed Node.js instead of using nvm, you can upgrade the version using the following command:

sudo npm cache clean -f
sudo npm install -g n
sudo n stable

This will clear the npm cache everything in, then install n-tools, and finally use n-tools to upgrade the current version to the latest stable version.

Summary

By using nvm, you can easily install and manage multiple Node.js versions, as well as switch versions. Use the --lts option to quickly install the latest stable version. If you are not using nvm, you can use the above command to upgrade to the latest version.

Upgrading Node.js not only brings better performance and more features, but also improves development efficiency by using the latest technologies and tools. Therefore, it is recommended that you upgrade Node.js in time and keep the latest version.
