原书第16页pyteer.py执行报错

[cailuo]

原书第16页代码执行时报以下错误：
pyppeteer.errors.BrowserError: Browser closed unexpectedly:
[0310/181827.222752:ERROR:zygote_host_impl_linux.cc(89)] Running as root without --no-sandbox is not supported. See https://crbug.com/638180.
系统：Ubuntu 18.04.4 LTS

解决办法：修改相应代码
browser = await launch()
修改为
browser = await launch({'args': ['--no-sandbox']})
