現場Railsを出版6年後にやってみる

$ rails _5.2.1_ new taskleaf -d postgresql

したら

.rbenv/versions/3.3.5/lib/ruby/gems/3.3.0/gems/psych-5.2.3/lib/psych.rb:370:in `load': wrong number of arguments (given 2, expected 1) (ArgumentError)

で怒られた。 rubyは 3.3.5

$ ruby -v                                          
=> ruby 3.3.5 (2024-09-03 revision ef084cc8f4) [arm64-darwin23]

これが関連していそう？

Ruby 2.5.1 って書いてあったのでそのバージョンを入れたいが、ビルドエラー

(macOS 14.4.1 on arm64 using ruby-build 20250130)

M1 Mac だからか？ログ見てねって書いてあるのでログを見る

html2slim が bundle insall でコケる

Installing hpricot 0.8.6 with native extensions
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

…中略…

An error occurred while installing hpricot (0.8.6), and Bundler cannot continue.

In Gemfile:
  html2slim was resolved to 0.2.0, which depends on
    hpricot

https://zenn.dev/yksn/articles/aff65f3afb73d0 を参考にさせていただき、最新の html2slim を使うように

bootstrapを追加したところ次のエラー

Gem Load Error is: bootstrap-rubygem requires a Sass engine. Please add dartsass-sprockets, sassc-rails, dartsass-rails or cssbundling-rails to your dependencies.

大人しく言われたやつ全部追加する。

gem 'bootstrap'
gem 'dartsass-sprockets'
gem 'sassc-rails'
gem 'dartsass-rails'

すると TSort::Cyclic エラーが出るので、sassc-rails だけを残す

gem 'bootstrap'
gem 'sassc-rails'
