- Incorrect installation or configuration
- Module not installed globally
- Module not compatible with the Node.js version
- Cache issues or corrupted module installation
Step-by-Step Solution
Follow these comprehensive steps to resolve the “Node.exe cannot find module jspdf” error:
Step 1: Check jsPDF Installation
Verify that jsPDF is installed correctly by running the following command in your terminal or command prompt:
npm ls jspdfIf jsPDF is not installed, run:

Frequently Asked Question
Don’t let the “module not found” blues get you down! We’ve got the answers to your jspdf woes.
I’ve installed jspdf using npm, but node.exe still can’t find it. What’s going on?
Check your package.json file to ensure that jspdf is listed under dependencies. If it’s not, try installing it again with the –save flag: npm install jspdf –save. This will update your package.json file and ensure that jspdf is properly installed.
I’ve installed jspdf globally using npm install -g jspdf, but node.exe still can’t find it. What’s the deal?
Installing jspdf globally only makes it available to the global npm scope, not to your specific project. Try installing it locally in your project directory using npm install jspdf to make it available to your node script.
I’ve tried both of the above solutions, but node.exe still can’t find jspdf. What’s my next step?
Time to get detective! Check your node_modules directory to ensure that jspdf is actually installed. If it’s not, try deleting the node_modules directory and running npm install again to reinstall all dependencies. If it is installed, try requiring it in your node script using const jsPDF = require(‘jspdf’); to see if that throws any errors.
I’m using a TypeScript project, and I’ve installed @types/jspdf, but node.exe still can’t find jspdf. What’s the issue?
TypeScript can be a bit finicky! Make sure you’ve installed the @types/jspdf package, but also ensure that you’ve installed the jspdf package itself using npm install jspdf. The @types/jspdf package only provides type definitions, not the actual jspdf library.
I’ve tried all of the above solutions, and node.exe still can’t find jspdf. What’s my last resort?
If all else fails, try uninstalling and reinstalling node.js and npm. This will reset your npm cache and ensure that all dependencies are properly installed. It’s a nuclear option, but sometimes it’s necessary to start from scratch!
