Not really sure what caused this but most likely exiting the terminal while my rails server which was connected to PostgreSQL database was closed (not a good practice I know but lesson learned!)
I've already tried the following:
- Rebooting my machine (using MBA M1 2020)
- Restarting PostgreSQL using homebrew
brew services restart postgresql
- Re-installing PostgreSQL using Homebrew
- Updating PostgreSQL using Homebrew
- I also tried following this link but when I run
cd Library/Application\ Support/Postgresterminal tells me Postgres folder doesn't exist, so I'm kind of lost already. Although I have a feeling that deleting postmaster.pid would really fix my issue. Any help would be appreciated!

In this link you will see how it is solved (in C#) --> Selenium - SendKeys("@") write an "à"

I updated from ruby 2.7.1 to 3.1.1, then removed Gemfile.lock and ran
bundle update (it's on a dev branch, so I can throw it away if this is a bad idea, I just wanted to see if it would work).
bundle update succeeds, but when I start the server:

The problem is related to the Ruby 3.1 / Psych 4.x incompatibility described in this issue: https://bugs.ruby-lang.org/issues/17866
Ruby 3.0 comes with Psych 3, while Ruby 3.1 comes with Psych 4, which has a major breaking change (diff 3.3.2 → 4.0.0).
- The new YAML loading methods (Psych 4) do not load aliases unless they get the
- The old YAML loading methods (Psych 3) do not support the
At this point, it seems like anyone, anywhere that wants to load YAML in the same way it worked prior to Ruby 3.1, need to do something like this:

This seems to a be a known issue with Rails 7 and Devise now. To fix it in the meantime simply add the following line to your devise.rb.

From rails tailwind readme
Tailwind uses modern CSS features that are not recognized by the sassc-rails extension that was included by default in the Gemfile for Rails 6. In order to avoid any errors like SassC::SyntaxError, you must remove that gem from your Gemfile.

I have a standard rails app on rails 7 and I'm seeing this warning but not even sure where it comes from, any idea?...

There is currently an issue in the
mime-types-data gem related to a duplicate definition of this mime type. If you look inside your
Gemfile.lock file, you’ll probably find this gem used as a dependency. Luckily, this is just a warning without any consequences. Possible solutions are discussed in the issue.
