安装指定的浏览器, 如果本机已经安装过了,就不会安装了
playwright install chromeplaywright install msedge
Google Chrome 或 Microsoft Edge 安装不会被隔离。它们将安装在默认的全局位置,具体取决于您的操作系统。
如果提示已经在系统里面安装了chrome

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