前言

playwright 默认会下载 chromium,firefox 和 webkit 三个浏览器，目前支持通过命令下载的浏览器有：chromium、chrome、chrome-beta、msedge、msedge-beta、msedge-dev、firefox、webkit

命令行下载

使用playwright install命令默认会安装chromium,firefox 和 webkit 三个浏览器。

可以通过playwright -h命令查看目前支持的浏览器

>playwright install --helpUsage: playwright install [options] [browser...]ensure browsers necessary for this version of Playwright are installedOptions:--with-deps install system dependencies for browsers--dry-run do not execute installation, only print information--forceforce reinstall of stable browser channels-h, --help display help for commandExamples:- $ installInstall default browsers.- $ install chrome firefoxInstall custom browsers, supports chromium, chrome, chrome-beta, msedge, msedge-beta, msedge-dev, firefox, webkit.

从命令行帮助信息中可以看到支持的浏览器有:chromium, chrome, chrome-beta, msedge, msedge-beta, msedge-dev, firefox, webkit

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

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:/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("/")
