Ruby on rails Rails搭建的脚手架-引导应用程序

是否有人知道如何通过选择gem'rails'、'5.2.0'和'bootstrap'、'4.3.1'来解决脚手架问题，可能是因为无法生成scaffold.scss文件

我在Rails方面的知识太贫乏，无法理解以下项目执行结束时的解释：

rails generate scaffold Something first second

最后，脚手架断裂，原因如下：

1。使用bootsnap

  ...
        invoke    scss
        create      app/assets/stylesheets/somethings.scss
    /usr/local/rvm/gems/ruby-2.4.3/gems/bootsnap-1.4.0/lib/bootsnap/load_path_cache/core_ext/kernel_require.rb:21:in `require': cannot load such file -- sass/css (LoadError)
          from /usr/local/rvm/gems/ruby-2.4.3/gems/bootsnap-1.4.0/lib/bootsnap/load_path_cache/core_ext/kernel_require.rb:21:in `block in require_with_bootsnap_lfi'
          from /usr/local/rvm/gems/ruby-2.4.3/gems/bootsnap-1.4.0/lib/bootsnap/load_path_cache/loaded_features_index.rb:80:in `register'
  ...

      ...
        invoke    scss
        create      app/assets/stylesheets/somethings.scss
    /usr/local/rvm/gems/ruby-2.4.3/gems/activesupport-5.2.2/lib/active_support/dependencies.rb:291:in `require': cannot load such file -- sass/css (LoadError)
          from /usr/local/rvm/gems/ruby-2.4.3/gems/activesupport-5.2.2/lib/active_support/dependencies.rb:291:in `block in require'
          from /usr/local/rvm/gems/ruby-2.4.3/gems/activesupport-5.2.2/lib/active_support/dependencies.rb:257:in `load_dependency'
  ...

2。没有启动快照

  ...
        invoke    scss
        create      app/assets/stylesheets/somethings.scss
    /usr/local/rvm/gems/ruby-2.4.3/gems/bootsnap-1.4.0/lib/bootsnap/load_path_cache/core_ext/kernel_require.rb:21:in `require': cannot load such file -- sass/css (LoadError)
          from /usr/local/rvm/gems/ruby-2.4.3/gems/bootsnap-1.4.0/lib/bootsnap/load_path_cache/core_ext/kernel_require.rb:21:in `block in require_with_bootsnap_lfi'
          from /usr/local/rvm/gems/ruby-2.4.3/gems/bootsnap-1.4.0/lib/bootsnap/load_path_cache/loaded_features_index.rb:80:in `register'
  ...

      ...
        invoke    scss
        create      app/assets/stylesheets/somethings.scss
    /usr/local/rvm/gems/ruby-2.4.3/gems/activesupport-5.2.2/lib/active_support/dependencies.rb:291:in `require': cannot load such file -- sass/css (LoadError)
          from /usr/local/rvm/gems/ruby-2.4.3/gems/activesupport-5.2.2/lib/active_support/dependencies.rb:291:in `block in require'
          from /usr/local/rvm/gems/ruby-2.4.3/gems/activesupport-5.2.2/lib/active_support/dependencies.rb:257:in `load_dependency'
  ...

我在尝试运行

rails-generate-scaffold-help

时遇到了类似的错误。是的

.../ruby-2.6.0/gems/activesupport-5.2.3/lib/active_support/dependencies.rb:291:in `require': cannot load such file -- sass/css (LoadError)

我的gem文件中没有bootsnap，但我有sassc-rails gem

# Use SCSS for stylesheets
gem 'sassc-rails', '~> 2.1'

sassc rails的最新版本是2.1.2。尝试运行

bundle update sassc rails

。这就是我修复它的原因。
