【问题描述】：

在Node.js 项目中更新/升级Playwright 的正确方法是什么？
我试图在官方文档中找到它，但没有找到任何具体内容。

即我有这个简单的项目：

{
  "name": "cool-tests",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {},
  "keywords": [],
  "author": "",
  "license": "ISC",
  "devDependencies": {
    "@playwright/test": "^1.28.1"
  }
}

使用最新的Playwright 版本以及兼容的浏览器维护该项目的最佳方式是什么？

【解决方案1】：

您可以npm i @playwright/test@latest 获取最新版本

然后npx playwright install 安装浏览器。

【解决方案2】：

检查包是否需要更新：

npm outdated @playwright/test

Playwright updade 可以通过运行进行：

npm i @playwright/test

通常在 Playwright 更新后，浏览器需要更新：

npx playwright install

常见问题

如果在 Playwright 版本更新后未执行命令 npx playwright install，并且测试运行如下：

npx playwright test

然后 Playwright 会自动识别旧浏览器，抛出错误并建议安装更新的浏览器。
