Error: CalcHist - object has no property: ranges

[black-posterus]

使用官方进行读取图片并进行直方图计算
代码如下

  const img = cv.imread(imgPath, cv.IMREAD_GRAYSCALE);
  const histSize = [256];
  const channels = [0];
  const ranges = [0, 256];
  console.log('img',img)
  const hist = cv.calcHist(img, channels, new cv.Mat([256], [1], cv.CV_32F), histSize, ranges);
  return hist;

打印的图片数据如下

img Mat {
  step: 375,
  elemSize: 1,
  sizes: [ 3243, 375 ],
  empty: false,
  depth: 0,
  dims: 2,
  channels: 1,
  type: 0,
  cols: 375,
  rows: 3243 }

你好，方便给我一份编译之后的opencv4nodejs么，我本机怎么都安装不上，试了网上各种办法，放弃了，想着直接拷贝到项目内部引用
