    折腾：
    【未解决】Mac中用playwright自动操作浏览器实现百度搜索
    期间，参考Python版Playwright的官网教程：
    microsoft/playwright-python: Python version of the Playwright testing and automation library. (github.com)
    去Mac中搭建开发环境和初始化。

    page=<Page url='about:blank'>
    page=<Page url='https://www.baidu.com/'>
    说明正常能跑了。初始化结束了。
    不过要搞清楚，如何显示浏览器，即非无头模式：
    看到官网
    microsoft/playwright-python: Python version of the Playwright testing and automation library. (github.com)
    “# Use playwright.chromium, playwright.firefox or playwright.webkit
    # Pass headless=False to see the browser UI”
    去试试：
    ?
    1
    browser = chromiumBrowserType.launch(headless=False)
    结果：
    是可以启动Chromium浏览器的。
    继续，是可以看到打开了百度首页的：
    【总结】
    此处Mac中初始化Python版Playwright环境：
    安装playwright：
    ?
    1
    pip install playwright
    初始化playwright，去安装浏览器内核：
    ?
    1
    playwright install
    此处下载安装了：
    • chromium
      • 位置：/Users/xxx/Library/Caches/ms-playwright/chromium-857950
      • 效果：
    • firefox
      • 位置：/Users/xxx/Library/Caches/ms-playwright/firefox-1238
      • 效果：
    • webkit
      • 位置：/Users/xxx/Library/Caches/ms-playwright/webkit-mac10.14-special-1443
