1. 报错1：Most likely the page has been closed

pyppeteer.errors.NetworkError: Protocol Error (Runtime.callFunctionOn): Session closed. Most likely the page has been closed.

使用pyppeteer采集京东的时候,总数到7~8页的时候就报错.
谷歌发现了这样的解决方案:

照着修改了一下源码,就解决了这个问题,在此记录一下.

2. 报错2：error while loading shared libraries: libX11-xcb.so.1

在ubuntu16.04上，使用python3.6运行pyppeteer的demo：

import asyncio
from pyppeteer import launch

async def main():
    browser = await launch()
    page = await browser.newPage()
    await page.goto('http://example.com')
    await page.screenshot({'path': 'example.png'})
    await browser.close()

asyncio.get_event_loop().run_until_complete(main())

报错如下：

pyppeteer.errors.BrowserError: Browser closed unexpectedly:
/home/ubuntu/.local/share/pyppeteer/local-chromium/575458/chrome-linux/chrome: error while loading shared libraries: libX11-xcb.so.1: cannot open shared object file: No such file or directory

搜索后，找到这条答案github issue
发现安装以下依赖后，报错解决：

sudo apt-get install -y libx11-xcb1 libxrandr2 libasound2 libpangocairo-1.0-0 libatk1.0-0 libatk-bridge2.0-0 libgtk-3-0 libnss3 libxss1
