Hello, I’m attempting to install Discourse for development on my PC, however running bundle exec rake db:migrate causes this error to appear:

```plaintext
ArgumentError: wrong number of arguments (given 1, expected 0; required keywords: site_setting_name, title, raw)
/home/mihco/discourse/lib/seed_data/topics.rb:126:in `create_topic'

/home/mihco/.rbenv/versions/3.0.1/bin/bundle:23:in `<main>'
Tasks: TOP => db:migrate
(See full trace by running task with --trace)

```

It is an issue with the create\_topic function, but I am unable to figure out how to change the parameters being passed as the migration is happening. What can I do about the extra arguments being passed?

Hello Michal 👋🏾

Which of the #dev-install guides did you follow to do this install?

Beginners guide to install Discourse on Windows 10 for Development. I’m using WSL2 with Ubuntu 2 for the installation. The installation went smoothly at first and I was able to run the server successfully when I installed Discourse about 2 weeks ago but now it started to show me that error

I had a similiar problem. Downgrading ruby from 3.0.0 to 2.7.2 solved it for me.

Yes, Discourse master isn’t yet compatible with Ruby 3. I got past the seeding errors by adding two double-splats to [topics.rb](https://github.com/discourse/discourse/blob/master/lib/seed_data/topics.rb), but then get _Job exception: wrong number of arguments_ errors when starting the server.

The [README](https://github.com/discourse/discourse/blob/master/README.md) currently asks for “Ruby 2.7+”, so it should be changed.
