What happens if you run "pub serve --verbose" from the command line?

I try run "pub serve --verbose" show message below

"Dart_LoadScriptFromSnapshot: Unable to deserialize snapshot correctly"

[nex3]

It looks like pub isn't executing at all. This sounds like a VM issue.

Removed Area-Pub, Pub-Serve labels.
Added Area-VM label.

I'm also seeing this. Is there a snapshot cache that can be cleared out?

[sethladd]

Did you happen to use the auto-update feature of Dart Editor?

I'm currently getting the same error, but my use case is different. I'm using the Sublime Text dart plugin.

And I'm install dart using Harald's ppa at: https://launchpad.net/~hachre/+archive/ubuntu/dart

My SDK path is set up correctly for the sublime package.

Here is my output from the console:

Running pub...
Dart_LoadScriptFromSnapshot: Unable to deserialize snapshot correctly.
[Finished in 0.1s with exit code 255]

I got it when using webstorm. It's not a dart editor issue, it appears to
be a go issue triggered by running pub (trying to deserialize a snapshot
created by a previous version of the vm, I assume).

Reinstalling the DartEditor solved the issue.

This happened to me too when I updated from 1.6 to 1.7.2 using the "Check for update…" option on the Help About dialog (on a Windows 8.1, 64 bit machine). However, I was pleasantly surprised to discover that my working environment was restored simply by replacing the original install with a version downloaded and installed (unpacked) from the Dart web site rather than via the editor.

For myself, using the ppa on ubuntu, doing apt-get upgrade also solved this issue.

I'm also on Windows 8.1 64-bit

Upgrading from 1.6.0 to 1.7.2 using the "Check for Update" button also made pub fail constantly. Trying fresh reinstall now.

Windows 7 64-bit

Upgraded from 1.6.x to 1.7 via "Check for Update"

pub cache repair didnt work
deleting the snapshots did not help
reinstalling Dart Editor helped :)

What are an official position of Google Dart developers?
What do they recommend?

[clayberg]

In versions prior to 1.7, there were some known cases where the update would only partially complete (usually due to Dartium currently running at the same time as the update and thereby preventing Dartium itself from being updated). That problem should be fixed in 1.7 but the fix won't really have an effect until users are updating from 1.7 to 1.8 in the future. We are speculating that this issue might be due to a partial update (although several comments also suggest it might be a separate problem or that there are a couple different problems being reported here). We had not seen Dart_LoadScriptFromSnapshot reference in an issue related to a failed update, so the original report might be unrelated to an update issue (even if many of the follow-up comments are update related).

A reinstall of Dart Editor (which also means a reinstall of the Dart SDK, Dartium, etc.) is always a good idea if you are experiencing weird problems like this. Most of the time, that seems to fix the problem.

Removed Area-VM label.
Added Area-Editor, Editor-Updater labels.

[clayberg]

I'm not convinced that the original issue reported here is update related. If it is, then it is a dup of Issue #17018 which was fixed for 1.7 a few weeks ago.

Added this to the 1.8 milestone.
Removed Priority-Unassigned label.
Added Priority-Medium, Duplicate labels.
Marked as being merged into #17018.
