I am going through the open-source Spree commerce tutorial. I am new to Ruby, so I just installed Ruby 2.7.2 and Rails 6.1. Unfortunately, Spree doesn't support Rails 6.1 yet, as described here: Bundler could not find compatible versions for gem “rails”.... So, I followed the solutions provided on that SO post and modified my Gemfile to set rails (and railties) to 6.0.3. That seemed to fix the error mentioned on that SO post...
But now when trying to run the command from the tutorial
"bundle exec rails g spree:install --user_class=Spree::User", I'm getting the error:
C:/Program Files/Ruby27-x64/lib/ruby/gems/2.7.0/gems/railties-6.0.3/lib/rails/application/configuration.rb:156:in `load_defaults': Unknown version "6.1" (RuntimeError)
Why is this happening, and how do I resolve this error?
Thank you in advance!
Get to the config/application.rb file in your app's folder and set the line with
config.load_defaults 6.1
to the below
config.load_defaults 6.0
The problem is, when you initially ran rails new command, the generators set the rails version to 6.1, which doesn't change when you specified 6.0.0 as version in Gemfile.

Goal: Upgrade legacy app step by step as recommended by the RailsGuides: Upgrading Ruby on Rails (from ruby 2.3.1 and rails 4.2.2)
Expected result: rake assets:precompile completes successfully without a gem psych alias error: Psych::BadAlias
Help needed: Can someone please tell me how to implement the recommended solution: Psych::AliasesNotEnabled: Alias parsing was not enabled. To enable it, pass `aliases: true` to `Psych::load` or `Psych::safe_load` . What is (a) the code and (b) which file does it belong in. Full details follow.
Actual result:
I am updating an application from ruby 2.3.1 and rails 4.2.2: I stepped through major ruby revisions, i.e., 2.4, 2.5, 2.6, and am currently running 2.7.0 I updated rails to ~> 5.0 and then issues with the psych gem arose:
Problem: Running: rake assets:precompile led to: rake aborted! / Psych::BadAlias: Cannot load database configuration / Unknown alias: default / Caused by: Psych::BadAlias: Unknown alias: default / error: Precompiling assets failed
The recommended solution is: Psych::AliasesNotEnabled: Alias parsing was not enabled. To enable it, pass `aliases: true` to `Psych::load` or `Psych::safe_load`
I learned that psych 3.1.0 is a "default gem" (when I tried to delete / reinstall psych since it wasn't in my Gemfile or Gemfile.lock). So, I added gem 'psych', '~> 5.0', '>= 5.0.1' to the Gemfile and installed it, ran bundle install, and then ```rake assets:precompile`` -- which returned the same psych aliases error.
Unfortunately, I don't know how to pass `aliases: true` to `Psych::load` or `Psych::safe_load`
The accepted answer to this SO Q&A was helpful: visit_Psych_Nodes_Alias: Unknown alias: default (Psych::BadAlias)
Adding the recommended module YAML as lib/yaml.rb (the right place?) didn't resolve the issue.
I did more research and discovered a Rails patch: https://discuss.rubyonrails.org/t/cve-2022-32224-possible-rce-escalation-bug-with-serialized-columns-in-active-record/81017 which noted that rails 5.2.8.1 (among others was "fixed"). So I upgraded to rails 5.2.8.1 and the error persisted.
Then, since the SO Q&A cited above ended with a "Note for Rails users (>= 7.0.3.1)" and the rails patch said rails 7.0.3.1 was a "fixed version", I upgraded to rails 7.0.3.1 and added the recommended code - from the Note - to resolve the psych issue:
# config/initializers/activerecord_yaml.rb
ActiveRecord.use_yaml_unsafe_load = true
It didn't work. rails app:update recommended numerous changes and, when running rake assets:precompile, I get an unrelated sprockets / popper.js error (probably higher in the stack than the psych error). So, I downgraded the app to rails 5.2.8.1 (with ruby 2.7.0) and am again getting the psych alias error when running rake assets:precompile
Hopefully, resolution is as simple as someone telling me how to implement the recommended solution: Psych::AliasesNotEnabled: Alias parsing was not enabled. To enable it, pass `aliases: true` to `Psych::load` or `Psych::safe_load` .
Also, what's a reasonable approach for the step-by-step upgrade of my code. I.e., once this issue is resolved for rails 5.2.8.1 should I skip ahead to the next fixed version (6.0.5.1)? The SO Q&A suggests different versions of psych for different versions of ruby; the issues are also related to different versions of rails.
Thank you in advance for your help. (I've returned to coding after a 3+ year break.)
use a psych version below 4 and it should work again. It's because of a breaking change in PSYCH:load in v4. If you want to use a newer version, aliases: true would be necessary... am also upgrading old rails apps. it started breaking on upgrade rails 5.0 to 5.1
I popped this error when running rails db:seed after updating a legacy Rails app.
Fixed this error by removing gem versions in my gem file and running bundle update
My Faker gem was set to ~> 2.7.0 and wasn't updating with the rest of my app.
It should tell you which gem is causing the YAML parsing error. It's most likely not the PSYCH gem.
Thank you this community for getting me started on the right path. Specifying rails version to use when creating a new application gets me close, but the differing ruby version is what is throwing me off. I'm running into an error after running rails new that I'm not sure where to begin to resolve it. I gather from the error that my command is missing a parameter, but I can't determine what it is.
Any advice?
I would like to create a rails 5.2.6 project and I'm finding consistent responses elsewhere indicating that my approach to getting a rails project created with a specific version is to:
install the rails gem with gem install rails -v 5.2.6
create a new rails project, specifying the rails version with rails _5.2.6 new appName
I think I'm on to it. Did a specific google search for compatibility of Ruby 3 with Rails 5 and appears this is the likely problem.
I've now run 'rvm install 2.7.4' then 'rvm use 2.7.4' but still seems to be using ruby 3 in the command. The new error:
user#ubuntudev:~/railsprojects$ rails _5.2.6_ new rpapitest
/home/user/.rbenv/versions/3.0.0/lib/ruby/3.0.0/rubygems.rb:281:in `find_spec_for_exe': can't find gem railties (= 5.2.6) with executable rails (Gem::GemNotFoundException)

Try with rbenv global 2.7.4 if you have rbenv installed
When deploying basic app for the first time to Heroku I had to change my Rails Version to 6.0.3.5 from 6.1.3 because Heroku wasn't working on Rails 6.1.3. After changing the version to 6.0.3.5 in the Gemfile and running "bundle" and "bundle update". I am getting a Runtime error as attached. I am a beginner, help to right direction would be great.
Look into your config/application.rb file. You will find there following line:
config.load_defaults 6.1
Rails are trying to load default configuration for version 6.1, but it is not there on rails 6.0.
Just change this line to:
config.load_defaults 6.0
and it should work unless you are using more stuff from 6.1 in your app.
I am trying to run an old rails app, but I am receiving this error after calling $ rails server:

I am brand new to Rails, and I really don't know what this means/where to start. The app is supposedly built on 2.3.8. My computer says I have 2.4.1 and 2.3.18 installed.
I would like to know if I should install 2.3.8, or if I should upgrade to the latest version? Also I don't understand the error that is coming up, where should I look in the app to fix this - or is this a Rails problem?
Verify the version your project is built type bundle show inside it. It's gonna show all the gems and your respective versions.
And to check the rails version just type rails -v in your terminal.
The gemfile in the app folder should tell you what version of rails it is.
You can use bundle update to update the version or if you have a newer version and want an older version, do gem uninstall rails and then gem install rails -v "version number" for example, gem install rails -v 2.3.8.
You can check the rails version on Gemfile.
Try the command rake about to see the application environment.
I would suggest to have your environment setup same on the Gemfile, your application might have compatibility issues if you use a lower version.
I am trying to run https://github.com/netguru/people but keep getting issues. When I push it to heroku i get errors, when I copied the files to my projects folder and run 'rails server' I get rails server
Your Ruby version is 2.1.1, but your Gemfile specified 2.0.0
I updated the ruby version in gem file but still run into issues.
Any help would be appreciated. Running Mac OSX Mavericks
I believe you've got your answer here https://github.com/netguru/people/issues/3
try to do:
gem install bundler rails
and then just do
bundle
