【问题描述】：

将我的 Playwright 项目打包到 Docker 映像中后出现一些错误。我在 Playwright 中使用 Firefox。

Dockerfile

FROM mcr.microsoft.com/playwright:next

WORKDIR /app

COPY package.json package-lock.json ./

RUN npm ci

COPY . .

RUN npx playwright install

CMD ["node","index.js"]

Package.json 依赖项

"@extra/humanize": "^4.2.2-next.616",
"playwright": "^1.15.0",
"playwright-extra": "^4.2.1-next.616"

index.js

const { firefox } = require('playwright');

(async () => {
  const browser = await firefox.launch();
  const page = await browser.newPage();
  await page.goto('http://whatsmyuseragent.org/');
  await page.screenshot({ path: `example.png` });
  await browser.close();
})();

它构建得很好，但是当我运行它时，我收到了这个错误：

browserType.launch: Protocol error (Browser.enable): Browser closed.

==================== Browser output: ====================

<launching> /ms-playwright/firefox-1225/firefox/firefox -no-remote -headless -profile /tmp/playwright_firefoxdev_profile-q4UuZi -juggler-pipe -silent

更新：

如果有人遇到同样的问题，我发现 Docker 映像在 MacBook M1（我正在运行）上无效:(

【问题讨论】：

嘿！对于 1.16+ 版本（大约一个月后发布），应该有可用的 M1 Docker 映像。目前您已经可以使用docker pull mcr.microsoft.com/playwright:next-focal，这应该可以工作。

标签： docker firefox playwright

【解决方案1】：

正如您已经说过的，这是一个错误（现在在功能请求中），因为 MS Devs 提供的 docker 文件在 M1 Mac 上失败。
