gm/convert 找不到二进制文件 Node.js pdf 到图像的转换

gm/convert binaries can't be found Node.js pdf-to-image conversion

我正在使用 https://www.npmjs.com/package/pdf2pic 将我的 PDF 转换为图像。

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)

错误:

brew install imagemagick

问题依然存在。我该如何解决?
