🐛 BUG: Port 8787 in use fails, but doesn't exist

[geelen]

What version of Wrangler are you using?

2.0.2

What operating system are you using?

Mac

Describe the Bug

Had something else running on 8787, and running wrangler dev I got this:

for people googling:

⬣ Listening at http://localhost:8787
✘ [ERROR] 12:43:36 pm Error: listen EADDRINUSE: address already in use 127.0.0.1:8787

      at Server.setupListenHandle [as _listen2] (node:net:1334:16)
      at listenInCluster (node:net:1382:12)
      at GetAddrInfoReqWrap.doListen [as callback] (node:net:1520:7)
      at GetAddrInfoReqWrap.onlookup [as oncomplete] (node:dns:73:8) {
    code: 'EADDRINUSE',
    errno: -48,
    syscall: 'listen',
    address: '127.0.0.1',
    port: 8787
  }

If I hit b, I get a browser window open like nothing happened, it's just showing the wrong project.

Can this automatically jump to an open port? Or at least crash completely?

Thanks for the issue @geelen - we were prematurely setting the configuration port value to the default of 8787 rather than doing it in the wrangler dev command, where it uses a library called getPort().

I have a fix coming within the hour.
