Just got this with Dart 3.1.5 SDK:

$ dart pub global activate webdev

Hi @mnordine! What Dart version are you on?

@elliette

Just got this with Dart 3.1.5 SDK

[mnordine]

Entire company is stalled on this, major deploy from yesterday delayed in CI. Any workarounds?

[mnordine]

I figured it out with dart run build_runner build for now.

Glad you got it working! I'm unable to reproduce with the WebDev 3.0.7+1 and Dart 3.1.5 (build completes successfully, see below), so I'm going to close this issue.

I was able to "fix" it locally on my machine by dart pub upgrade, and the transitive dep build_daemon went from 4.0.0 to 4.0.1.

Seems to have worked after that.

Perhaps something was broke in that version. If so, users will hit it. Hopefully they dart pub upgrade or find this.
