将 Playwright 项目包装在 Docker 镜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，我收到此错误:
browserType.launch: Protocol error (Browser.enable): Browser closed.

更新:
如果有人遇到同样的问题，我很遗憾地发现 Docker 镜像在 MacBook M1(我正在运行)上无效:(
最佳答案
正如您已经说过的，这是一个错误(现在位于功能请求中)，因为 MS Devs 提供的 docker 文件在 M1 Mac 上失败。
这里是功能请求的链接 - https://github.com/microsoft/playwright/issues/7723
