Troubleshooting issues with Discourse environments
Are you having trouble setting up Discourse? Here are some basic things to check before reaching out to the community for help:
Are you running Ruby 2.5 or later?
Discourse is designed for Ruby 2.5 or later. We recommend 2.5.2 or later. You can check your version by typing
ruby -vand checking the response.
Are you on Postgres 10 or later with HSTORE enabled?
You can check your postgres version by typing
psql --version. To see if hstore is installed, open a session to postgres and type
\dxand see if hstore is listed.
Have you run
We frequently update our dependencies to newer versions. It is a good idea to run
bundle installevery time you check out Discourse, especially if it's been a while.
Did you run
bundle updatewill download gem versions that we haven't tested with. The Gemfile.lock has the gem versions that Discourse currently uses, so
bundle installwill work. If you ran update, then you should uninstall the gems, run
git checkout -- Gemfile.lockand then run
Have you migrated your database?
Our schema changes fairly frequently. After checking out the source code, you should run
bundle exec rake db:migrate && RAILS_ENV=test bundle exec rake db:migrate
Do the tests pass?
If you are having other problems, it's useful to know if the test suite passes. You can run it by first using
RAILS_ENV=test bundle exec rake db:drop db:create db:migrateand then
bundle exec rspec. If you experience any failures, that's a bad sign! Our master branch should always pass every test.
Have you updated host_names in your database.yml?
If links in emails have localhost in them, then you are still using the default host_names value in database.yml. Update it to use your site's host name(s).
Are you having problems bundling:
ArgumentError: invalid byte sequence in US-ASCII An error occurred while installing active_model_serializers (0.7.0), and Bundler cannot continue. Make sure that `gem install active_model_serializers -v '0.7.0'` succeeds before bundling.
Try this in console:
$ export LANG="en_US.UTF-8" $ export LC_ALL="en_US.UTF-8"
