PHP Fatal error: Class 'Drupal\Core\ContentNegotiation' not found

[huijing]

The error occurred when I ran drush pm-update on Drupal 8 Beta 14 to upgrade to Beta 15. The terminal output is as follows. This issue does not appear to have any significant implications from a functionality perspective. Drush version used is 8.0-dev.

Project drupal was updated successfully. Installed version is now 8.0.0-beta15.

This seems a spurious error, due to Remove ContentNegotiation and embed functionality in the middleware. The http_negotiation.format_negotiator service has been removed and the service container needs to be recompiled. I don't understand why the cache rebuild didn't do it though.

Same thing happened to me. No visible errors on the site though, everything seems to work.

The error is also occurring going from beta 13 to beta 15. The site generally seems to be working otherwise.

I get the same error, after that i can not create views, contenttypes or content.
I'm using postgres.

So, i tested to clear the cache, by step 5 i got this error:

Not a Drush issue. These are the troubles one has to fix (sometimes by hand) when adopting a Drupal 8 beta. We have no resources to support it here.
