ERROR: Failed to download Chromi

https://github.com/GoogleChrome/puppeteer/issues/1597

使用国内Chromium源
https://npm.taobao.org/mirrors

# // > https://npm.taobao.org/mirrors
# // export PUPPETEER_DOWNLOAD_HOST=https://npm.taobao.org/mirrors
# // set PUPPETEER_DOWNLOAD_HOST=https://npm.taobao.org/mirrors

npm config set puppeteer_download_host=https://npm.taobao.org/mirrors
npm i puppeteer

或者用淘宝的cnpm 安装，自动使用国内源

npm install -g cnpm --registry=https://registry.npm.taobao.org
cnpm i puppeteer

还可以手动下载Chromium文件，解压后放在本地
https://npm.taobao.org/mirrors/chromium-browser-snapshots/

• 放在模块的默认读取目录下
  例如 node_modules\puppeteer\.local-chromium\win64-526987(系统类型-版本号)\chrome-win32(下载的文件名)\
  版本号来自 puppeteer/package.json->puppeteer.chromium_revision，具体见lib/Downloader.js
• 放在其他目录，运行时设置路径参数
  puppeteer.launch({executablePath:'ChromiumExePath'})
