"The system cannot move the file to a different disk drive" running "pub run test"

[DanTup]

I don't know if pub run test is the righty way to run tests (I thought there was a pub test?!) however I got this strange error when running it...

I'm on Windows 10, happens in both PowerShell and standard command windows.

I cloned https://github.com/dart-lang/convert, ran pub get then pub run test and got the following:

PS M:\Coding\Applications\convert> pub run test
Directory listing failed, path = 'test\packages\analyzer\dart\*' (OS Error: The system cannot move the file to a different disk drive.
, errno = 17)
dart:io                                    _Directory.listSync
package:test/src/runner/loader.dart 91:49  Loader.loadDir
package:test/src/runner.dart 240:60        Runner._loadSuites.<fn>
dart:_internal                             ListIterable.forEach

package:test/src/runner.dart 239:24        Runner._loadSuites
package:test/src/runner.dart 116:18        Runner.run.<async>

This is an unexpected error. Please file an issue at http://github.com/dart-lang/test
with the stack trace and instructions for reproducing the error.
PS M:\Coding\Applications\convert>

I've gotta go out, but I'll try and do some more debugging later.

AFAIK you can't have the Dart code on network drives.

It's just a standard drive:

My guess is that it's related to pub cache being on a different drive to my Dart code, I think the "move" in the error is a bit misleading.

[DanTup]

Ok, this is because pub cache is on a different drive. Therefore this is a dupe of dart-lang/pub#880. It kinda sucks, but the symlinks stuff kinda sucks anyway. For me it's trivial for me to move my cache so it's not a big deal.

dart-lang/pub#880

AFAIK it is one of the next tasks to make test compatible with --no-package-symlinks which would solve this issue.
