I am trying to resize an image with node-imagemagick library, but it is not working.
the code i am using to resize is
im.resize({
srcPath: __dirname+'originalimage.jpg',
dstPath: __dirname+'resized.jpg',
width: 50
}, function(err, stdout, stderr){
if (err) throw err;
});
It throws the error
Error: Command failed: Invalid Parameter - -set

On windows you also need to install the imagemagick exe. The nodejs imagemagick library is just a wrapper for imagemagick exe. So it will not work untill the imagemagick exe is intalled and convert and identify executable are in path.
It is just that you haven't installed ImageMagick in your system. If you are using a Linux distribution you can do:
sudo apt-get install imagemagick
