尝试使用puppeteer插件，但我一直收到未处理的承诺拒绝错误：ReferenceError：找不到变量：require

如何解决尝试使用puppeteer插件，但我一直收到未处理的承诺拒绝错误：ReferenceError：找不到变量：require

我的程序应该在一个名为suplexed.com的网站上搜索给定的运动鞋代码，并返回给定运动鞋可用的最小尺寸的价格。当我使用节点在控制台中运行单个.js文件时，我确实得到了我想要的值。但是，当我运行应该使用.js文件的HTML文件时，出现以下错误

Unhandled Promise Rejection: ReferenceError: Can't find variable: require

这是我的JavaScript代码，名称为“ scrapers.js”。我添加了评论以更好地理解。使用节点在控制台中运行.js文件时，没有问题。但是，当使用通过HTML的实时服务器运行目录时，该目录不起作用。这里的问题在于代码的前几行，因为它不会过去

async function scrapestockx(url){
  const site = "stockx.com";
  let puppeteer = require('puppeteer-extra');
  let pluginStealth = require('puppeteer-extra-plugin-stealth');
  puppeteer.use(pluginStealth());

  puppeteer = require('puppeteer');
  
  const browser = await puppeteer.launch({headless: false})
  const page = await browser.newPage();
  await page.goto(url,{waitUntil: 'networkidle0'});


  // get the value for the row sneaker size for stockx
  await page.waitForXPath('//*[@id="pricer_table"]/tbody/tr[4]/td[1]');
  const [sneakersize]= await page.$x('//*[@id="pricer_table"]/tbody/tr[4]/td[1]');
  
  const sneakersizeTxt = await sneakersize.getProperty('textContent');
  const sneakersizeRawTxt = await sneakersizeTxt.jsonValue(); 


  // get the value for the row sneaker size price for stockx
  await page.waitForXPath('//*[@id="pricer_table"]/tbody/tr[4]/td[2]/span[1]');
  const [sneakerPrice]= await page.$x('//*[@id="pricer_table"]/tbody/tr[4]/td[2]/span[1]');
   
  const sneakerPriceTxt = await sneakerPrice.getProperty('textContent');
  const sneakerPriceRawTxt = await sneakerPriceTxt.jsonValue(); 
  
  // print the sneaker size and price to verify TO CONSOLE
  console.log(printSizeAndPrices(sneakersizeRawTxt,sneakerPriceRawTxt,site)); 

  // print the sneaker size and price TO WEBSITE
  let sneakerPrint = document.createElement("p");
  sneakerPrint.textContent = printSizeAndPrice(sneakerPriceRawTxt,site)
  document.querySelector("body").appendChild(sneakerPrint);

  browser.close();
}

document.querySelector("#search-form").addEventListener("submit",function(e){
  e.preventDefault()

  // get sneaker code using the textBox created in html
  // const sneakerCode = e.target.elements.enterBox.value
  
  // manually enter a unique sneaker code
  const sneakerCode = "XXXXXX-XXX";

  // print sneaker code to console to verify
  console.log("sneakerCode: " + sneakerCode)
 
  // create the website address of the sneaker
  const address = ('https://suplexed.com/web/' + sneakerCode)

  // print website address to verify
  console.log("address: " + address)

  // call the function to retrieve the wanted values for the chosen sneaker
  scrapestockx(address)
})

function printSizeAndPrice(sneakersizeRawTxt,site){
  return `${sneakersizeRawTxt} is ${sneakerPriceRawTxt} on ${site}`;
}

这是我的HTML代码

<!DOCTYPE html>
<html>
    <head>
    
    </head>
    <body>
        <p>Enter a sneaker code and hit the button to search</p>

        <form id = "search-form">
            <input type = "text" placeholder = "XXXXXX-XXX" name = "enterBox">
            <button>Search</button>
        </form>

        <script src = "scrapers.js"></script>
    </body>
</html>

解决方法

这不是解决问题的完整方法，但确实使我遇到了一个新的错误，现在我正在研究该错误。在index.html文件中，我只是在包含require.js文件的主要js标签之前添加了一个脚本标签

<script src = "require.js"></script>
