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

Question

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 ：

(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

我试过了 ：

brew install imagemagick

而且这个问题仍然存在。我该如何解决这个问题？
