javascript - 为什么在 Linux 上运行简单的 puppeteer 脚本时会出现 "Browser is not downloaded"错误？

Question

我多次尝试手动下载 headless 浏览器以及其他一些尝试，但错误仍然存​​在。运行 Linux Mint。

                                                                                                                                           
(node:25262) UnhandledPromiseRejectionWarning: Error: Browser is not downloaded. Run "npm install" or "yarn install"
    at ChromeLauncher.launch (/home/oem/web-scraping/puppetering/node_modules/puppeteer/lib/Launcher.js:236:15)

代码如下:

#!/usr/bin/node

const puppeteer = require('puppeteer');

async function scrape() {
    const browser = await puppeteer.launch();
    const page = await browser.newPage();
    await page.goto('https://ratings.fide.com/top.phtml?list=men');
    const [ele] = page.$x('//*[@id="main-col"]/table[2]/tbody/tr[2]/td/table/tbody/tr[2]/td[2]/a')
    const name = await ele.getProperty('text')
    
    console.log(name)
};

scrape()

我已经以 root 身份使用全局标志安装了 puppeteer。然后，我以用户身份启动了一个项目，并遇到了与您相同的问题。

在项目中运行 npm install puppeteer --save 并作为用户触发 Chromium 的下载，并解决了此错误。

不知道为什么 pupeeter 的全局安装没有触发相同的依赖项。
