            psql: error: connection to server on socket "/tmp/.s.PGSQL.5432" failed: No such file or directory
            Asked 2022-Apr-04 at 15:46

            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:

            1. Rebooting my machine (using MBA M1 2020)
            2. Restarting PostgreSQL using homebrew brew services restart postgresql
            3. Re-installing PostgreSQL using Homebrew
            4. Updating PostgreSQL using Homebrew
            5. I also tried following this link but when I run cd Library/Application\ Support/Postgres terminal 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!

            Resetting PostgreSQL

            My original answer only included the troubleshooting steps below, and a workaround. I now decided to properly fix it via brute force by removing all clusters and reinstalling, since I didn't have any data there to keep. It was something along these lines, on my Ubuntu 21.04 system:

            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).

            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 aliases: true argument.
            • The old YAML loading methods (Psych 3) do not support the aliases keyword.

            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.

            Rails 7 asset pipeline SassC::SyntaxError with Tailwind

            Answered 2021-Dec-18 at 05:58

            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.

            That's related to some unexpected issue related to the use of --nomultiline or IRB.conf[:USE_MULTILINE] = false inside .irbrc file.

            Similar issue with the hack

            To avoid that issue, you can just skip using --nomultiline option, when launching your rails console.

            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.

            UPD: on January 6th, 2022 Rails 7.0.1 was released:

            The focus of this release is bring support to Ruby 3.1

            Amongh other Ruby 3.1-related issues it brought a fix for this problem. So upgrade to Rails >= 7.0.1.

            Add gem 'net-smtp', require: false to your Gemfile and run bundle.

            Similarly I assume you may have problems with net-imap and net-pop and so have to add them until a new mail gem version is released.
