I was trying to do: arc diff --update to update svn diff for review and
PHP Fatal error: Class 'ArcanistDifferentialRevisionRef' not found in
on line 201
<<<  <exec> 31,061,830 us
[2013-10-08 07:15:04] EXCEPTION: (Exception) Unable to read results from
background linting and unit testing. You can try running arc diff again
with --background 0 at
#0 ArcanistDiffWorkflow::run() called at
Does anyone know how to fix this problem? i upgrade arcanist and
libphutil to newest version, but it doesn't work.
I found a email about the same problem in hive-user email group
but there is no answer.
