无法启动webkit或使用playwright截图

Question

但它对铬起作用。

playwright: 1.8.0节点: 14.15 Ubuntu: 20.04

这是我的代码。

const playwright = require("playwright");

(async () => {
  for (const browserType of ["chromium", "firefox", "webkit"]) {
    const browser = await playwright[browserType].launch();
    const context = await browser.newContext();
    const page = await context.newPage();
    await page.goto("http://whatsmyuseragent.org/");
    await page.screenshot({ path: `example-${browserType}.png` });
    await browser.close();
  }
})();

Answer 1

我解决了我缺少libgstreamer-plugins-bad1.0-0:amd64这个库

Answer 2

在ubuntu20.04上，我在运行我的第一个playwright脚本时遇到错误:通过npm i -D playwright (playwright v1.10.0和v10.19.0)每个playwright install instructions安装后的node first_script.js

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

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

我看到的错误包括：

• “加载共享库时出错: libharfbuzz-icu.so.0:无法打开共享目标文件:没有这样的文件或目录”

根据几个bugs #1935 #2621，运行以下命令可以让我成功运行：

sudo apt-get install libgles2 gstreamer1.0-libav libharfbuzz-icu0 libwoff1 libgstreamer-plugins-bad1.0-0 libgstreamer-gl1.0-0 libwebp-dev

然后尝试在同一个ubuntu20.04 node second_script.js上用chrome(Chrome)，firefox和webkit运行第二个脚本

const playwright = require('playwright');

(async () => {
  for (const browserType of ['chromium', 'firefox', 'webkit']) {
    const browser = await playwright[browserType].launch();
    const context = await browser.newContext();
    const page = await context.newPage();
    await page.goto('http://whatsmyuseragent.org/');
    await page.screenshot({ path: `example-${browserType}.png` });
    await browser.close();
  }
})();

并得到错误：

文件/home/playwright/.cache/ms-playwright/firefox-1238/firefox/libxul.so：

• pid=532053 XPCOMGlueLoad错误pid=532053 libdbus-glib-1.so.2:无法打开共享对象文件:没有这样的文件或目录pid=532053无法加载XPCOM.

已安装firefox并成功运行第二个脚本：

sudo apt-get install firefox
