如果提示已经在系统里面安装了chrome

可以先关闭正在运行的chrome 浏览器，使用以下命令安装到最新版

playwright install --force chrome  


安装完成会显示版本号，以及安装的位置

指定 channel 打开浏览器

默认情况下，chromium.launch() 不带 channel 参数打开的是 chromium 浏览器

from playwright.sync_api import sync_playwright
# 上海悠悠 wx:283340479  
# blog:https://www.cnblogs.com/yoyoketang/

with sync_playwright() as pw:
    browser = pw.chromium.launch(headless=False)
    page = browser.new_page()

    page.goto("https://www.baidu.com/")

Google Chrome 和 Microsoft Edge浏览器都是用的 chromium 内核，所以只需加一个channel="chrome" 即可打开谷歌浏览器

from playwright.sync_api import sync_playwright
# 上海悠悠 wx:283340479  
# blog:https://www.cnblogs.com/yoyoketang/

with sync_playwright() as pw:
    browser = pw.chromium.launch(headless=False, channel="chrome")
    page = browser.new_page()

    page.goto("https://www.baidu.com/")

添加channel="msedge" 即可打开Microsoft Edge浏览器

from playwright.sync_api import sync_playwright
# 上海悠悠 wx:283340479  
# blog:https://www.cnblogs.com/yoyoketang/

with sync_playwright() as pw:
    browser = pw.chromium.launch(headless=False, channel="msedge")
    page = browser.new_page()

    page.goto("https://www.baidu.com/")
