How to install Node.js offline under Windows system

It is very common to use Node.js in daily development, but sometimes you want to install Node.js without a network but cannot complete it. At this time, you need to install it offline. This article will introduce how to install Node.js offline under Windows systems.

1. Download the Node.js installation package

First, we need to download the Node.js installation package from the official website. In the download page, we can select the corresponding version to download. Usually we can select the LTS version to download.

Download address: https://nodejs.org/zh-cn/download/

2. Install Node.js

After the download is completed, double-click to run the installation package , enter the installation interface, click "Next" to continue.

In the next interface, we need to select the installation path of Node.js. By default, Node.js will be installed in the C:\Program Files\nodejs path, which can be changed according to your needs.

Next, we need to choose the components to use. Normally, we can choose two options, npm and Add to PATH, which make it easier for us to use Node.js and npm commands.

Click "Next" to continue, then click "Install" to start the installation. After the installation is complete, click "Finish" to exit the installation program.

3. Configure npm

After Node.js is installed, we also need to configure npm so that it can use offline mode. The specific steps are as follows:

1. Create a new folder. For example, we can create a new folder "npm-offline" in the root directory of drive D.
2. Use npm to initialize the folder: Enter the following command in the command line:

npm init --offline

3. Modify the npm configuration file: Set the path of the npm configuration file (npmrc) is D:\npm-offline. Enter the following command in the command line:

npm config set cache D:\npm-offline --global

4. Use offline mode

After completing the above steps, we can use Node.js for offline development. It should be noted that when using npm to install a third-party module, you need to first download the installation package of the module from the official website and place it in the D:\npm-offline path.

In the command line, we can use the following command to install the local module:

npm install <module> --offline</module>

If you need to install the global module, enter the following command in the command line:

npm install -g <module> --offline</module>

So far, we have completed the offline installation and configuration of Node.js.

Summary: Node.js plays a very important role in daily development, but it is often embarrassing to install it without a network. Through the offline installation method introduced in this article, we can easily solve this problem, providing more possibilities for our development work.
