Issue: I am trying to start postgres server via command "postgres". I am getting the following error "zsh command not found postres"

I installed postgres@12 via homebrew. I see postgresql@12 in /usr/local/var/

The only things in /usr/local/var are: homebrew, log, and postgresql@12

My .zshrc file looks like this as it stands

I have tried this a number of different ways. First I tried with RVM and it was just error after error and missing dependencies. Then I tried Rbenv and it was very much the same. Now, I have a combo of chruby and ruby-install to handle my versions of Ruby, but I can't update Bundler. It says that I am currently on 1.17.2, but I need 1.17.3. How do I upgrade this? I have searched everywhere, but all the solutions seems to be for RVM.

When I try to update Bundler this is the error that I get:

I've tried this in both Ruby 3.0.2 and Ruby 2.73, with similar results. It shouldn't matter for the problem at hand, as I've also tried this under different shells and ruby managers, but this is primarily being tested under:

• fish, version 3.3.1
• chruby: 0.3.9
• chruby-fish: 0.8.2
• macOS 11.6

I'm trying to use the poorly (or possibly even undocumented) DelegateClass from the Delegator class to create a facade for YAML::Store that allows me to read and write arbitrary keys to and from a YAML store. However, I clearly don't understand how to properly delegate to the YAML::Store instance, or to override or extend the functionality in the way that I want.

For simplicity, I wrote my example as a self-executing Ruby file names example.rb, so please scroll to the end to see the actual call to the classes. I'm hoping that my mistake is fairly trivial, but if I'm fundamentally misunderstanding how to actually perform the delegation of CollaboratorWithData#write and ollaboratorWithData#read to MultiWriter, please educate me.

Note: I know how to solve this problem by simply treating YAML::Store as an object instantiated within my class, or even as a separate object that inherits from YAML::Store (e.g. class MultiWriter < YAML::Store) but I'm very much trying to understand how to properly use Forwardable, SimpleDelegator, and Delegate to wrap objects both in the general case and in this particular use case.

Hello it's my first question here. I'm trying to build a redmine system on my server but facing some problems.

my system - ubuntu20.04 + nginx1.18 + mariadb10.3.30 + ruby2.7.4 + redmine4.2.2 / use rbenv to install ruby

when I'm trying to connect the redmine server, I got this error

I've been trying to fix this error, but I can't find a solution yet. I'm about to deploy a Rails application to production using nginx, puma, and capistrano, but I get an error when running this command line bundle exec cap production deploy:initial. Right after initializing 'PUMA:START' Top Task, my terminal throws an error message and exit the process.

shared/bundle/ruby/2.6.0/gems/puma-5.2.2/lib/puma/cli.rb:50:in `initialize': invalid option: --daemon (OptionParser::InvalidOption) puma stderr: Nothing written Tasks: TOP => puma:start (See full trace by running task with --trace)

I think this is caused by a wrong command line executed before which is:

I am wanting to update my Rails EB Linux to 2.12.2 from 1.11.8, so I cloned the environment and committed to it but I am getting this error:

I'm new to ruby, I was trying to run my first app but when I start the server I get this error:

I saw a lot of similar questions here, but nothing of provided advises has helped. Every time I run cap production deploy I got error:

I've been at this for about 16 hours and throwing in the towel. I've successfully deployed an rails app with capistrano before and I copied everything initially, but I can't get past assets:precompile. Migration doesn't work either, but one thing at the time.
