Try upgrading pub to the latest bleeding edge and running "pub cache repair". This should have been fixed in dart-lang/sdk@c0e3d5f.

It works, but the fact that it prints
"Wrong script snapshot version, expected 'f6711525cff9f7d0d08595166664b767' found 'a3a313ea90040f8a3aaa5f443ecbb3db'"
is not nice at all.
One way of avoiding this would be to add something like "dart --test-snapshot-compatibility file.snapshot", so one can ask the VM whether it can read the snapshot, instead of just trying to run it and see what happens :-/
If one would implement this, you could also use "exec dart ..." instead.

I agree. I filed issue dart-lang/sdk#20802 and issue dart-lang/sdk#20784 when we first started supporting snapshots, but nothing has happened there.
Added Fixed label.

Originally opened as dart-lang/sdk#21904
Reproduction on my machine:
$ pub global activate -sgit https://github.com/dart-lang/dart_style
$ dartformat
Wrong script snapshot version, expected 'f6711525cff9f7d0d08595166664b767' found '74629058babcf012a75ec8e5b364e464'
Pub should make sure to invalidate script snapshots and re-generate them (on demand) when the dart binary changed.
