How to install nodejs on virtual machine ubuntu

Ubuntu is a popular open source operating system that is secure, easy to use, and easy to customize. Node.js is a JavaScript runtime based on the Chrome browser V8 engine. It performs well on the server side and has the advantages of fast response and high stability. In this article, we will introduce how to install Node.js on the virtual machine Ubuntu, so that you can develop and run Node.js applications more conveniently.

Step 1: Install the virtual machine

First, we need to install a virtual machine software on the Windows computer, such as VMware Workstation, etc. A virtual machine is a virtual computer environment that can completely simulate a computer's hardware, operating system, application software and other elements, allowing us to run the Ubuntu operating system on a Windows system. After the installation is complete, you can start downloading the Ubuntu image file.

Step 2: Install the Ubuntu system

Put the downloaded Ubuntu installation disk image file (ISO) into the virtual machine software and create a new virtual machine.

After starting the virtual machine, you will automatically enter the Ubuntu installation interface. Follow the interface prompts to install. During this process, you can choose to install the Ubuntu system in a virtual machine, or you can choose to install the Ubuntu system on the hard disk of a real computer.

Note: It is recommended that the hard disk space allocated to Ubuntu should not be less than 20G for subsequent use. It is also recommended to allocate enough memory and processor cores to the virtual machine so that Node.js can run smoothly.

Step 3: Install Node.js

After installing Ubuntu, use the following command in the terminal to update the Ubuntu software source:

sudo apt update

Then install Node.js, and make sure it is the latest version:

sudo apt install nodejs

sudo apt install npm

These two commands will automatically install Node.js from Ubuntu software Download the Node.js and npm packages from the source and install them into your Ubuntu system. After the installation is complete, you can verify the version of Node.js:

node -v

npm -v

These commands will output the version numbers of Node.js and npm , proving that the installation of Node.js and npm has been completed.

Step 4: Test Node.js

In order to verify whether Node.js is successfully installed and running normally, you can enter the following command in the terminal:

node - e "console.log('Hello, Node.js')"

This command will output the "Hello, Node.js" string, indicating that Node.js is installed successfully and you can start writing and running Node.js Applied.

Summary:

The above is how to install Node.js on a virtual machine. In a virtual machine, installing Ubuntu system and Node.js is basically the same as on a physical machine, except that there is an additional virtualization process. If you are a beginner or want to learn Node.js, this method is a good choice. You can make full use of the characteristics of the virtual machine and achieve quick installation of the software. Hope this article can help you.
