Solving the Puppeteer Installation Issue in Node.js: A Troubleshooting Journey

As developers, we often face challenges while working with different tools and libraries. One of the issues I encountered recently was with installing puppeteer, the popular browser automation library, in a Node.js environment. The error message I received left me scratching my head, and I want to share my troubleshooting journey with you. Hopefully, this post will save you some valuable time if you find yourself in a similar situation.

The Problem: Unusual Node.js Error During Puppeteer Installation
While installing puppeteer, I encountered a strange error that read:

npm error command failed
npm error command C:\WINDOWS\system32\cmd.exe /d /s /c node install.mjs
npm error 'node' is not recognized as an internal or external command,
npm error operable program or batch file.

At first glance, this looked like a typical issue with the Node.js installation, and I assumed something was wrong with my setup. However, this was very misleading because all other dependencies and my Node.js app worked fine without any issues. The error was solely related to the installation of puppeteer. So why would Node.js suddenly complain about the node command?

Step 1: Investigating the Root Cause
Given that the error suggested Node.js wasn't recognized, I started by verifying that the Node.js binary was properly installed and accessible from my command line. I ran the following command:

node -v

The response was the expected output, confirming that Node.js was installed and working correctly. This made the error message even more perplexing, as it directly contradicted the results of this simple test.

I also checked the system's PATH environment variable, which should ensure the correct location of the Node.js executable. To my surprise, this didn't resolve the issue either. The error persisted, which led me to believe that the problem wasn't with the PATH configuration but something more specific to how puppeteer handles its installation scripts.

After a half day of trouble shooooot..........

I then realized that the issue might be specific to the way puppeteer handles its installation scripts. It turns out that puppeteer uses a script (install.mjs) to install its necessary components, and this is where things were failing.

Step 2: Trying Puppeteer-Core as a Solution

At this point, after much frustration and multiple attempts at fixing the issue, I stumbled upon a suggestion to use puppeteer-core. This is essentially a lighter version of puppeteer that doesn’t come with a bundled Chromium browser, and it’s designed for environments where you want to provide your own Chromium or Chrome installation.

The command I used was:

npm install puppeteer-core

Surprisingly, this worked without any errors, and the installation completed successfully. The issue was that puppeteer was trying to download and install Chromium automatically, which was likely conflicting with my system’s environment or some other configuration.

Step 3: Conclusion – The Lesson Learned

This experience was frustrating because of the misleading error message. Instead of an informative message related to the issue, I received a generic node not recognized error, which made it seem like a problem with Node.js itself. In reality, the issue was with the specific way puppeteer was being installed, especially when it attempts to download and set up its Chromium dependency.

The solution turned out to be using puppeteer-core instead of the full puppeteer package. This version of the library doesn’t require the automatic Chromium installation, and thus bypasses the issue entirely.

Why This Is Important for Developers

This kind of experience is a great reminder that error messages in Node.js (and any other environment) can sometimes be misleading. A vague or generic message might not be directly related to the root cause. When troubleshooting, it’s essential to think critically about the context of the problem, experiment with different approaches, and don’t hesitate to search for alternative solutions.

This issue with puppeteer also highlights the importance of understanding the libraries and dependencies you’re using. By being aware of the differences between puppeteer and puppeteer-core, you can make more informed decisions based on your environment and needs.

Final Thoughts

If you’re facing this same issue with nodejs, I hope this post helps you resolve it faster than I did. The key takeaway is that not all installation issues are related to the basics, such as Node.js installation itself.
