无法在 Puppeteer 上查询选择器（类型错误：selector.startsWith 不是函数）

我安装了 Puppeteer 并想查询一个选择器来处理它。 但是我遇到了

TypeError: selector.startsWith is not a function

我试图通过添加

toString()

这是我试过的两种表达方式：

await page.$eval('#firstName', elem => elem.click());

await page.waitForSelector('#firstName');

两者均无效并产生相同的错误。

我还尝试安装旧的 puppeteer 和 node 版本，但仍然相同。 我该如何解决这个问题？

所有错误日志信息为：

file:///C:/Users/User/Desktop/mail/node_modules/puppeteer-core/lib/esm/puppeteer/common/GetQueryHandler.js:51
                if (selector.startsWith(prefix)) {
                             ^

我产生相同错误的完整代码示例是：

const puppeteer = require('puppeteer');

(async () => {
  const browser = await puppeteer.launch({headless: false});
  const context = await browser.createIncognitoBrowserContext();
  if (context) {
    const page = await browser.newPage();

    await page.goto(';cc=TR&dsh=S-519439412%3A1682412535258329&flowEntry=SignUp');
  
    // Set screen size
    await page.setViewport({width: 1080, height: 1024});
    //await page.$eval('#firstName', elem => elem.click());
    const username = await page.waitForSelector('#firstName');
    await page.focus(username)
    await page.keyboard.type('test54')
  }

})();

您需要单击选择器

#firstName

await page.focus(username);

到

await username.click();

这将解决错误，如果你想使用隐身，那么

const page = await browser.newPage();

应该是

const page = await context.newPage();
