折腾:
【未解决】Mac中用puppeteer自动操作浏览器实现百度搜索
期间,先参考自己教程
puppeteer · 解放你的双手:自动化测试
puppeteer python
对应python版本是:pyppeteer
pyppeteer
pyppeteer · PyPI
pip install pyppeteer
pyppeteer/pyppeteer: Headless chrome/chromium automation library (unofficial port of puppeteer)
但是是非官方

安装后,去写代码试试
https://miyakogi.github.io/pyppeteer/index.html
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.

安装完毕:
 pyppeteer-install
[W:pyppeteer.chromium_downloader] start chromium download.
Download may take a few minutes.

[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:
