Error! Unknown option '-'

[linen1996]

I directly run cwebp.exe like this bat code, it works, but the JavaScript code webpConverter.cwebp(input, output, options, callback), it got error Error! Unknown option '-'.

:: bat code
D:\Workspaces\front-end\project\image2html\node_modules\webp-converter/lib/libwebp_win64/bin/cwebp.exe -q 75 "D:/Workspaces/front-end/project/image2html/images/4 - 28172-1565573276-704911963.png" -o "D:/Workspaces/front-end/project/image2html/images/imagemin/4 - 28172-1565573276-704911963.webp"

// JavaScript code
let imageDirPath = 'D:/Workspaces/front-end/project/image2html/images'
let imageminRelativeFolder = 'imagemin'

function getImageminDir (dirPath) {
  return `${imageDirPath}/${imageminRelativeFolder}`
}

function toWebp (file) {
  let input = `"${imageDirPath}/${file}"`
  let output = `"${getImageminDir()}/${util.replaceExtnameToWebp(file)}"`
  let options = `-q 75`
  let callback = function (status, error) {
    if (status == 101) {
      console.log('101, error)
    }
  }
  webpConverter.cwebp(input, output, options, callback)
}
