找不到 gm/convert 二进制文件 Node.js pdf 到图像的转换

Question

I am using https://www.npmjs.com/package/pdf2pic to convert my PDF to image.

const PDF2Pic = require('pdf2pic');

const pdf2pic = new PDF2Pic({
  density: 100, // output pixels per inch
  savename: 'untitled', // output file name
  savedir: './images', // output file location
  format: 'png', // output file format
  size: '600x600', // output size in pixels
});

const file = "/Users/kar1/Downloads/bw.pdf"
async function recognizeFile(file) {
  pdf2pic.convertBulk(file, -1).then((resolve) => {
    console.log('image converter successfully!');

    return resolve;
  });
}

recognizeFile(file)

The error:

(node:32605) UnhandledPromiseRejectionWarning: Error: Could not execute GraphicsMagick/ImageMagick: gm "identify" "-ping" "-format" "%p" "/Users/kar1/Downloads/bw.pdf" this most likely means the gm/convert binaries can't be found

I tried:

brew install imagemagick

And the issue still persists. How can I solve this?
