firefox 本地编剧

Question

您如何使用已安装的本地 firefox 运行 playwright？

笔记：。 我需要能够指定可执行文件，因为我实际上正在开发 firefox 所以我可能有一个自定义构建，但是。 第一步是让它在官方构建中运行。

我试过这个

// test.mjs
import { firefox } from 'playwright-core';

const executablePath =  "C:\\Program Files\\Mozilla Firefox\\firefox.exe";

async function main() {
  const browser = await firefox.launch({
    executablePath,
    headless: false,
  });
}

main();

但我得到了一堆错误

❯ node .\test.mjs
node:internal/process/promises:246
          triggerUncaughtException(err, true /* fromPromise */);
          ^

browserType.launch: Browser.enable): Browser closed.

  name: 'Error'
}

尝试了 MacOS 以及 Window（当然在 MacOS 上路径不同）。 此过程适用于 Chrome

我相信您的 FF 与 Playwright 支持的版本不匹配，

最新的Playwright 1.29.2支持107，而现在的FF是108。
