I have a problem with redmine plugin migration. While migrating:
exec rake redmine:plugins:migrate RAILS_ENV=production
I get errors:
/var/lib/gems/2.3.0/gems/htmlentities-4.3.1/lib/htmlentities/mappings/expanded.rb:465: warning: key "inodot" is duplicated and overwritten on line 466
yard not installed (gem install yard)
Migrating ...
...
Most interesting, that
sudo gem install yard
gives
...
Successfully installed yard-0.9.5
Done installing documentation for yard after 0 seconds
1 gem installed
but after that
$ bundle show yard
Could not find gem 'yard'.
Did you mean yard?
So how should I install yard?
I have installed Redmine V3.3.1 on Ubuntu 16.04 with apache2 and passenger, Ruby V2.3
