安装后，去写代码试试
首次使用时，会下载Chromium，约100MB
如果不想内部自动安装，则手动事先安装：pyppeteer-install
which pyppeteer-install /Users/crifan/.pyenv/shims/pyppeteer-install
发现是有的。
那去安装试试：
pyppeteer-install [W:pyppeteer.chromium_downloader] start chromium download. Download may take a few minutes. 2%|█▎ | 1607680/86759503 [00:09<05:22, 263751.77it/s]
安装完毕：
pyppeteer-install [W:pyppeteer.chromium_downloader] start chromium download. Download may take a few minutes. 100%|████████████████████████████████████████████████████████████████████████| 86759503/86759503 [02:38<00:00, 546119.68it/s] [W:pyppeteer.chromium_downloader] chromium download done. [W:pyppeteer.chromium_downloader] chromium extracted to: /Users/crifan/Library/Application Support/pyppeteer/local-chromium/588429
继续去写代码
import asyncio
from pyppeteer import launch
async def main():
browser = await launch()
page = await browser.newPage()
baiduUrl = "https://www.baidu.com"
await page.goto(baiduUrl)
await page.screenshot({'path': 'baidu.png'})
await browser.close()
asyncio.get_event_loop().run_until_complete(main())调试发现：
没有启动Chrome浏览器啊
但是可以继续调试
不过后续功能是正常的：
可以截图出来
至此，算是环境基本OK了。
但是要去搞清楚：
【已解决】pyppeteer功能正常但是没有启动Chrome浏览器
至此，环境才算正常。
【总结】
Mac中搭建pyppeteer的环境：
（1）安装pyppeteer
pip install pyppeteer
（2）安装（脚本运行时所需的）Chromium浏览器（约100MB）
pyppeteer-install
此处安装到了：
/Users/crifan/Library/Application Support/pyppeteer/local-chromium/588429
（3）写代码
import asyncio
from pyppeteer import launch
async def main():
browser = await launch(headless=False)
page = await browser.newPage()
baiduUrl = "https://www.baidu.com"
await page.goto(baiduUrl)
await page.screenshot({'path': 'baidu.png'})
await browser.close()
asyncio.get_event_loop().run_until_complete(main())即可：
启动Chromium浏览器，并打开百度，和本地截图
效果：
