Uglify-js In Nodejs "cannot Find Module"

Here i am creating application to compress a javascript file Steps i made, Installed nodeJS in my local machine checked node and npm is working Installed 'uglify-js' by 'npm insta

Solution 1:

You installed uglify globally, it won't be "visible" to your package. You want to run npm install uglify-js (without the -g) inside the directory/package where your script is located.

If you're keeping track of dependencies in a package.json (you should be!), npm install --save uglify-js will automatically add it there for you.
