ruby-on-rails - Rails 的脚手架 - 引导应用程序

问题描述

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，这可能是由于无法制作 scaffold.scss 文件。

我对 Rails 的了解太少，无法理解执行结束时的解释：

rails generate scaffold Something first second

最后脚手架被打破了解释：

1. 带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'
  ...

2.没有bootsnap

      ...
        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'
  ...

解决方案

我尝试运行时遇到了类似的错误rails generate scaffold --help。它是

.../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 Gemfile 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。这就是为我解决的问题。
