Jimp.measureTextHeight例外：errorTypeError：无法读取的未定义的属性“lineHeight是”

    let Jimp = require('jimp');
    var sizeOf = require('image-size');
    var mergeImg =require('merge-img');
    var dimensions = sizeOf('image/wall.png');
    console.log(dimensions.width, dimensions.height);        
    let image = new Jimp(dimensions.width, dimensions.height, 'green', (err,       image) => {
      if (err) throw err
    })        
    let message = 'Here the text is being added in the bottom center of the image.'
    let x = 10
    let y = 10  

    try{
    var textHeight=  Jimp.measureTextHeight(Jimp.FONT_SANS_32_BLACK, 'Some string', 100);        
    console.log("text height -"+textHeight);     
    }catch(ex)
    {
     console.log("error" + ex)

    Jimp.loadFont(Jimp.FONT_SANS_16_BLACK)
      .then(font => {
