TypeError [ERR_INVALID_ARG_TYPE]:“原始"参数必须是类型为puppeteer node js的函数

问题描述

我在这里呆了一段时间，我不明白问题所在.有人在这个问题上启发了我.这是代码.

I am stuck here for a while I didn't understand the problem. Kindly someone enlightens me on this topic. here's the code.

const puppeteer = require('puppeteer');
(async() => {
    let infourl = 'https://www.imdb.com/title/tt0111161/?ref_=fn_al_tt_3';
    let browser = await puppeteer.launch();
    let page = await browser.newPage();
    await page.goto(infourl, { waitUntil:'networkidle2' });
    let data = await page.evaluate( () =>{
        let stats = document.querySelector('div[class="title_wrapper"]').innerText;
        return {stats};
    });
    console.log(data);
    debugger;
    await browser.close();
})();

这是日志::

internal/util.js:209
    throw new errors.TypeError('ERR_INVALID_ARG_TYPE', 'original', 'function');
    ^

推荐答案

它是puppeteer的最新版本.
您的脚本将在较低版本中正常运行.

It occurred to the latest version of puppeteer.
Your scripts will work properly in the lower version.

尝试以下脚本:
npm i -save [email protected]

Try this script:
npm i -save [email protected]
