## 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:
|
|
|
|
|
|
1. Are you running Ruby 2.0 or later?
|
|
|
|
Discourse is designed for Ruby 2.0 or later. We recommend 2.0.0 p353 or later. You can check your version by typing
|
|
`ruby -v` and checking the response.
|
|
|
|
|
|
2. Are you on Postgres 9.1 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 `\dx` and see if hstore is listed.
|
|
|
|
|
|
3. Have you run `bundle install`?
|
|
|
|
We frequently update our dependencies to newer versions. It is a good idea to run
|
|
`bundle install` every time you check out Discourse, especially if it's been a while.
|
|
|
|
4. Did you run `bundle update`?
|
|
|
|
Don't. Running `bundle update` will download gem versions that we haven't tested with.
|
|
The Gemfile.lock has the gem versions that Discourse currently uses, so `bundle install`
|
|
will work. If you ran update, then you should uninstall the gems, run
|
|
`git checkout -- Gemfile.lock` and then run `bundle install`.
|
|
|
|
5. Have you migrated your database?
|
|
|
|
Our schema changes fairly frequently. After checking out the source code, you should
|
|
run `rake db:migrate`
|
|
|
|
7. 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 `rake db:test:prepare` and then `rake spec`. If you
|
|
experience any failures, that's a bad sign! Our master branch should *always* pass
|
|
every test.
|
|
|
|
8. 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).
|
|
|
|
9. 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"
|
|
```
|
|
|
|
And/or this in top of `Gemfile`:
|
|
|
|
```
|
|
if RUBY_VERSION =~ /1.9/
|
|
Encoding.default_external = Encoding::UTF_8
|
|
Encoding.default_internal = Encoding::UTF_8
|
|
end
|
|
```
