nodeJS에서 pdf2pic 사용 시 에러

Question

import fromPath from 'pdf2pic' import fs from 'fs-extra' const { writeFileSync } = fs const pdfPath = process.argv[2] || 'untilted.pdf' const savePath = process.argv[3] || '.' const options = { density: 100, savePath }; const convert = new fromPath(pdfPath, options) const converted = [] convert.bulk(-1, true).then((outputs) => { for (let outputIndex = 0; outputIndex < outputs.length; ++outputIndex) { converted.push(outputs[outputIndex].base64) } writeFileSync(savePath + `/bundles`, JSON.stringify(converted)) })우분투 서버에서 작업 중입니다. 제가 작성한 코드가 아니라 분석하는 중인데 에러가 나더군요 그래서 GraphicsMagick 설치해줬는데도 아래 에러가 뜹니다.. pdf2pic 사용해보신 분 있으실까요?!(node:23) UnhandledPromiseRejectionWarning: Error: Could not execute GraphicsMagick/ImageMagick: gm "identify" "-ping" "-format" "%p" "-" this most likely means the gm/convert binaries can't be found at ChildProcess.

결국 외부 프로그램을 서브 프로세서에서 작동하는데 /usr/bin 경로에 관련된 프로그램을 설치하지 않았거나 pdf2pic이 설마 자기 모듈 경로에서 프로그램을 찾도록 하드 코딩을 .. 한 것은 아니지 않겠나요.
