Playwright: [BUG] unable to launch webkit on virtual box windows

[arjunattam]

Context:

• Playwright Version: 1.1.1
• Operating System: Windows 10 build 1809 (running on Virtualbox)
• Node version: 12.8
• Browser: WebKit

Code Snippet

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

(async () => {
  const browser = await webkit.launch({ headless: false });
  const page = await browser.newPage();
  await page.goto('https://example.com');
  await browser.close();
})();

Describe the bug

WebKit does not launch, in headless/headful modes. I can see the PlaywrightLibrary.dll file in the right directory though - unclear what the error message is referring to

Works for me out of the box on a fresh Win10 install

I get the same issue Window 2012 R2
Testing:
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();
}
})();

Chromium and Firefox output correctly.

Can you try Dependency Walker to find out what is the missing DLL for PlaywrightLib.dll.

[arjunattam]

That was helpful, @fujii! I realized I was on Windows 10 N that was missing a host of api-ms-win-core-* dlls. I installed Media Feature Pack and now I can run WebKit 🎉

@niksimms - can you try running Dependency Walker?

[fujii]

Ah, it's my fault. I assumed no one is using Windows 10 N.
I filed a WebKit bugzilla ticket.

If you are willing to contribute a patch, I'd be glad to review the patch.

I got the same error, I am on windows 7
Other browsers seems to work fine, except webkit

[fujii]

I believe upstream WebKit WinCairo port fiexed the issue. https://trac.webkit.org/r264188

Closing as the should be fixed in recent builds and we now also have launch doctor functionality which should help debugging such issues.
