NanoPi Node.js Installation

NanoPi is a great embedded system with high performance, low power consumption and reliability. It supports a variety of operating systems, including Linux, Android, etc., to meet the needs of different scenarios.

As a JavaScript runtime environment, Node.js allows developers to write programs on the server side and build high-performance, scalable network applications. Its features include event-driven, asynchronous I/O, etc., making it very suitable for the development of embedded systems.

This article will introduce how to install Node.js on NanoPi so that developers can use it to write applications on the platform.

Preparation work

Before starting to install Node.js, we need to do some preparation work:

1. Update system

The operating system used by NanoPi needs to be kept up to date so that it has the latest patches, features and security. We can update the system through the following command:

sudo apt-get update
sudo apt-get upgrade

2. Install the necessary software packages

Installing Node.js requires relying on some software packages, and we need to ensure that these packages have been Once installed in the system, you can run the following command to install:

sudo apt-get install build-essential libssl-dev curl

Install Node.js

There are two ways to install Node.js on NanoPi: one is through Node.js official Download the binary file from the website for installation; the other is to use the nvm tool for installation.

1. Installation through Node.js official website

This method requires developers to manually download the Node.js binary files and extract them to the specified directory. You can refer to the following steps for this process:

1.1 Download Node.js

You can download the binary file of Node.js through the Node.js official website, the download link is https://nodejs.org/ en/download/. It is recommended to download the latest stable version.

1.2 Unzip the file

After the download is completed, we need to unzip the file to the specified directory. You can use the following command to unzip:

cd ~
tar -xvf node-xxx.tar.gz
(其中 xxx 代表你下载的版本号)

1.3 Installation

After decompression is completed, we need to add the bin directory in the decompression folder to the PATH environment variable so that the node and npm commands can be used directly. You can use the following command to add:

export PATH=$PATH:/path/to/your/node/bin

(where /path/to/your/node/bin represents the bin directory path in your unzipped folder)

2. Use the nvm tool Installation

nvm is a Node.js version management tool that can easily install, switch and uninstall different versions of Node.js. Using nvm to install Node.js avoids us manually downloading binaries and makes it easier to manage multiple versions. The following are the specific steps:

nvm install stable

Run completed Finally, we can use the following command to detect whether Node.js is installed successfully:

node -v

If the version number of Node.js is displayed, the installation is successful.

Summary

Node.js is a development framework that is very suitable for embedded systems, and NanoPi is a hardware platform that is very suitable for embedded systems. In this article, we explain how to install Node.js on NanoPi so that developers can use it for development.
