When running pub_release from the alpha.11 build the following error is returned:

This occurs when trying to release pubspec_manager using the current package version number.

This is quite severe and brakes operation of DCLI

I do actually have a partial fix on master for this issue and with a little more work it is completely fixable.
However at the moment I'm trying to deal with a bigger issue:

dart-lang/sdk#52121

If you look at the final comment you can read about the problem.

This may mean that we have to make the dcli process calls async...

this should be resolved in 4.0.1-beta.1
