puppeteer的使用问题

问答

Qquanpf2481发布于8 年前最后回复8 年前|18 回复21823 浏览0 收藏

在阿里云服务器上，系统是Debian8.9，安装puppeteer是使用cnpm i puppeteer的命令安装的，安装也成功了，在进行测试的时候出现了问题，我的测试代码如下： const puppeteer = require('puppeteer');

(async () => { let browser = await puppeteer.launch({ executablePath: './chromium/chrome.exe', headless: false }); const page = await browser.newPage(); await page.goto('http://music.163.com/'); await page.screenshot({path: 'music.png'}); browser.close(); })(); 运行后出现如下的错误： (node:23748) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: Failed to launch chrome! spawn ./chromium/chrome.exe ENOENT

TROUBLESHOOTING: https://github.com/GoogleChrome/puppeteer/blob/master/docs/troubleshooting.md

(node:23748) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code. 请问一下有没有碰到这样的，怎么样来解决呢？？？感谢！！！

Error: Failed to launch chrome! spawn ./chromium/chrome.exe ENOENT

错误很明显chrome启动失败，executablePath: './chromium/chrome.exe' linux不可以用Windows的chromium，cnpm安装成功的话puppeteer不需要额外指定chromium路径。

@Zero2key 感谢回复！！！我修改了一下程序如下： const puppeteer = require('puppeteer');

(async () => { try{ let browser = await puppeteer.launch(); const page = await browser.newPage(); await page.goto('http://music.163.com/'); await page.screenshot({path: 'music.png'}); // browser.close(); }catch(err) { console.log('pid: ',process.pid,' ',err.stack); }

})(); 再次运行还是出现了如下错误： pid: 26774 Error: Failed to launch chrome! /var/webSpider/node_modules/_puppeteer@1.9.0@puppeteer/.local-chromium/linux-594312/chrome-linux/chrome: error while loading shared libraries: libX11-xcb.so.1: cannot open shared object file: No such file or directory

@atian25 我现在npm包的安装路径是/var/webSpider/，在这个路径下node_modules文件里包含一个_puppeteer@1.9.0@puppeteer，请问一下，chrome的路径应该怎么来设置呢？？新手，还望见谅。

那段报错的意思是，系统缺少依赖库，然后后面给了一个 URL，里面有相关的脚本

@atian25 感谢回复，对于这个问题我真的是一点头绪都没有，这个报错应该怎么来解决呢？？是因为我的npm依赖包不完整嘛？？？

安装puppeteer还有一种方法是跳过下载Chromium，然后手动安装chrome，比如下面

npm i --save puppeteer --ignore-scripts

手动安装chrome

sudo apt install google-chrome

截图功能

const puppeteer = require('puppeteer');

(async () => {
    const browser = await puppeteer.launch({ executablePath: 'google-chrome' });
    const page = await browser.newPage();
    await page.goto('https://y.qq.com');
    await page.screenshot({path: 'yqq.png'});
    browser.close();
})();
