How to Pass NPM Custom Args on Windows 10: A Simple Guide

If you are working with Node.js and NPM (Node Package Manager), you might have encountered the need to pass custom arguments while installing packages. This is particularly important when you want to customize the installation of packages, such as Puppeteer. However, Windows 10 users may face some challenges due to differences in how command-line commands are interpreted compared to Linux. In this guide, we will address a common issue and provide step-by-step instructions to help you pass custom NPM arguments seamlessly on Windows 10.

The Problem

Imagine trying to install a specific version of Puppeteer for Firefox on Windows, using a command like this:

This can be frustrating, especially when the same command works perfectly fine on Linux. So, how do you fix this on your Windows machine?

The Solution

Passing custom arguments on Windows requires a slightly different syntax. Here’s a straightforward process to successfully install Puppeteer for Firefox on Windows 10.

Step 1: Initialize Your NPM Project

If you haven’t already initialized your project, start by doing so. Run this command in your terminal:

This command sets up a new package.json file, which is essential for managing your project's dependencies.

Step 2: Install Puppeteer with Custom Argument

Once your project is initialized, you can proceed to install the desired version of Puppeteer along with the custom argument. Use the following command:

Step 3: Clean Up If Necessary

Important Note: If you are working within an existing project and have previously installed Puppeteer, you might run into issues where the correct Firefox build isn’t downloaded.

Solution: Before running the above installation command, delete the node_modules directory if it already exists in your project folder. You can easily do this by running:

This step ensures that a fresh version of Puppeteer is installed without conflicting with previous installations.

Conclusion

With these steps, you can easily pass custom NPM arguments on your Windows 10 machine without running into errors. The key points to remember are initializing your project with npm init, using the set command to specify environment variables, and ensuring a clean installation by removing the node_modules directory if it already exists.

Now you can confidently install NPM packages with custom arguments on Windows 10, making your development process more efficient and hassle-free! If you have any questions or encounter further issues, feel free to comment below.
