I tried pub serve on a couple of different projects (and with a couple of different ports)... same results.

[nex3]

This is caused by an IsolateSpawnException when loading the plugin isolate -- almost certainly because it can't find "package:polymer/transformer.dart".

Rob, did you run "pub get" before "pub build"? Are you sure your polymer version is up-to-date? Can you post your pubspec.lock file?

Yup. Up to date:

What surprises me the most is that Rob previously run 'pub build' and that worked fine.

Nathan - any clues on something windows specific that could be going on here?

Still seeing the same pub serve crash with 0.8.10.0_r29746.

I'm on Windows 8.1 64 bit and have the same issue. Not only with the polymer transformer, also with my own one. pub build works fine, but pub serve not.

Dart Editor version 0.8.7_r29341
Dart SDK version 0.8.7.0_r29341

I am running 32 bit Linux and have the same issue.

pub build without issue..
pub serve.. Transformer library "package:polymer/transformer.dart" not found.

Dart VM version: 0.1.2.0_r29778 on "linux_ia32"

I don't think this is Windows-specific. https://codereview.chromium.org/49293003/ should provide more information about what the underlying error is here, but we're holding off on committing it for the time being.

On my Mac, it looks like the issue may be that the pub server bound to "localhost" gets bound to an IPv6 address, which the isolate then fails to find. The actual error is:

IsolateSpawnException: 'HTTP error.'file:///var/folders/00/0v3s8000h01000cxqpysvccm003cg5/T/pub_Js1Jjo/runInIsolate.dart': Error: line 1 pos 1: library handler failed
import "http://::1:8080/packages/myapp/transformer.dart";

Note the "::1". Maybe we should use "127.0.0.1" as the default hostname?

I was having this problem on Mac too and I can confirm that removing the IPv6 directives from /etc/hosts solved the problem.

[sgjesse]

See issue #14924 regarding a URL with an IPv6 literal. It needs to be enclosed in square brackets. The import

import "http://::1:8080/packages/myapp/transformer.dart";

is wrong. It should be:

import "http://[::1]:8080/packages/myapp/transformer.dart";

[munificent]

Thanks, Søren! I have a proper fix for this in now.
