How to install the latest version of nodejs

With the development of Internet technology, Node.js has become the mainstream of Web development. Whether it is front-end or back-end development, you can use Node.js to improve work efficiency. If you haven't installed the latest version of Node.js yet, this article will introduce you to how to install the latest version of Node.js.

1. Download the latest version of Node.js

First we need to download the latest version of Node.js from the Node.js official website. On the https://nodejs.org/en/ website, we can see two different versions: LTS and Current.

LTS (Long-term support) version is a long-term support version. It is more stable and suitable for use in production environments, but its version update speed is slower and will not include the latest features. The Current version is the latest version and contains the latest features and optimizations, but due to the faster update speed, there may be some instability issues.

If you want to use Node.js in a production environment, it is recommended that you download the LTS version, otherwise it is recommended to download the Current version.

2. Install Node.js

After downloading the Node.js installation package, we can run it directly for installation. There are some issues you need to pay attention to during the installation process:

1. For Windows users, you need to install Microsoft Visual C 2015 Redistributable before installing Node.js.
2. For Linux and macOS users, you can install directly using the package manager. For example, on Debian/Ubuntu, you can use the following command to install:

sudo apt-get update
sudo apt-get install nodejs

For different systems, installation methods It may be slightly different, you need to refer to the corresponding documentation for operation.

3. Configure environment variables

After completing the installation of Node.js, we also need to configure some environment variables. These environment variables allow us to run Node.js and NPM (Node.js Package Manager) directly from the command line.

For Windows users, you can follow these steps:

1. Click "My Computer," right-click "Properties," and then select "Advanced System Settings."
2. In the "Advanced" tab, click "Environment Variables".
3. In "User Variables", find the "Path" line and click "Edit".
4. In the new interface that pops up, click "New" and then enter the installation path of Node.js, such as "C:\Program Files\nodejs".
5. Click "OK" to save the settings.

For Linux and macOS users, you need to enter the following command in the terminal:

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

Replace "/ usr/local/bin” with the installation path of Node.js.

4. Verify installation

Finally, we need to verify whether the Node.js we installed is available. Enter the following command on the command line:

node -v

If you can see the version number of Node.js, the installation is successful. If the prompt "node: command not found" is displayed, it means that Node.js has not been correctly added to the system environment variables. You need to check if there are any omissions in the previous steps.

Summary

It is not difficult to install the latest version of Node.js, just follow the steps above. After the installation is complete, we also need to configure some environment variables so that Node.js can run directly in the command line. If you want to learn Node.js in depth, you can check out the official documentation, which contains detailed usage instructions and sample code.
