centos 7下使用puppeteer访问页面报错解决

完整的报错信息如下:

{ Error: socket hang up
    at createHangUpError (_http_client.js:330:15)
    at Socket.socketOnEnd (_http_client.js:423:23)
    at Socket.emit (events.js:164:20)
    at endReadableNT (_stream_readable.js:1062:12)
    at process._tickCallback (internal/process/next_tick.js:152:19) code: 'ECONNRESET' }
(node:29975) UnhandledPromiseRejectionWarning: Error: socket hang up

    at endReadableNT (_stream_readable.js:1062:12)
    at process._tickCallback (internal/process/next_tick.js:152:19)

通过Google在https://github.com/GoogleChrome/puppeteer/issues/391#issuecomment-325420271找到可用的解决方法:

yum install pango.x86_64 libXcomposite.x86_64 libXcursor.x86_64 libXdamage.x86_64 libXext.x86_64 libXi.x86_64 libXtst.x86_64 cups-libs.x86_64 libXScrnSaver.x86_64 libXrandr.x86_64 GConf2.x86_64 alsa-lib.x86_64 atk.x86_64 gtk3.x86_64 ipa-gothic-fonts xorg-x11-fonts-100dpi xorg-x11-fonts-75dpi xorg-x11-utils xorg-x11-fonts-cyrillic xorg-x11-fonts-Type1 xorg-x11-fonts-misc -y

完整安装以上依赖就可以解决错误。

另外,在linux root账号下启动的puppeteer必须使用无沙箱模式,即:

const browser = await puppeteer.launch({ args: ['--no-sandbox']})

否则会报错。
