Error during the easy_gantt plugin installation

Added by Salvatore La Rocca about 6 years ago

Hello to everyone!

I'm trying to install the easy_gantt plugin with this commands:

1) $ bundle install
2) $ bundle exec rake db:migrate RAILS_ENV=production
3) $ bundle exec rake redmine:plugins:migrate RAILS_ENV=production

but, after the command number 2, i'm getting this error:

Rails Error: Unable to access log file. Please ensure that /opt/bitnami/apps/redmine/htdocs/log/production.log exists and is writable (ie, make it writable for user and group: chmod 0664 /opt/bitnami/apps/redmine/htdocs/log/production.log). The log level has been raised to WARN and the output directed to STDERR until the problem is fixed.
rake aborted!
