HarmonyOS 文本计算不准

定位到问题点是计算的时候fontsize必须带px，否则就会计算不准

代码如下

import measure from '@ohos.measure'
@Entry
@Component
struct Index {
  textSize : SizeOptions = measure.measureTextSize({
    textContent: "Hello word",
    fontSize: '50px'
  })
  build() {
    Row() {
      Column() {
        Text(`The width of 'Hello World': ${this.textSize.width}`).width(this.textWidth)
        Text(`The height of 'Hello World': ${this.textSize.height}`).width(this.textWidth)
      }
      .width('100%')
    }
    .height('100%')
  }
}
