Javascript Cheerio无法获取文本数据

我正在尝试从网站DOM节点获取文本值，并且我正在遵循一些google示例，但是我无法获取文本

const cheerio = require('cheerio');
const request = require('request-promise');

async function iniciar() {
    const $doc = await request({
        uri: '*******************',
        transform: body => cheerio.load(body)
    });
    const coat_price = $doc('#product-info > div > span.product-content-info-offer-price.offer-price.offer-price-js.product-price-amount-js');
    console.log(coat_price)
    console.log(coat_price.text())
}

这是输出的数据指令。所选文本输出为空白。

initialize {
  '0': {
    type: 'tag',
    name: 'span',
    namespace: 'http://www.w3.org/1999/xhtml',
    attribs: [Object: null prototype] {
      class: 'product-content-info-offer-price offer-price offer-price-js product-price-amount-js',
      'data-amount': ''
    },
    'x-attribsNamespace': [Object: null prototype] {
      class: undefined,
      'data-amount': undefined
    },
    'x-attribsPrefix': [Object: null prototype] {
      class: undefined,
      'data-amount': undefined
    },
    children: [ [Object] ],
    parent: {
      type: 'tag',
      name: 'div',
      namespace: 'http://www.w3.org/1999/xhtml',
      attribs: [Object: null prototype],
      'x-attribsNamespace': [Object: null prototype],
      'x-attribsPrefix': [Object: null prototype],
      children: [Array],
      parent: [Object],
      prev: [Object],
      next: [Object]
    },
    prev: {
      type: 'text',
      data: '\n\t\t\n\t\t',
      parent: [Object],
      prev: null,
      next: [Circular]
    },
    next: {
      type: 'text',
      data: '\n\t\t\n\t\t\t\t',
      parent: [Object],
      prev: [Circular],
      next: [Object]
    }
  } .....
}

有人知道会发生什么？

谢谢你的阅读

Maibe问题是我在网页上使用开发工具，而不是在源代码中？
