Question

当我这样做

gem 'bootstrap', '~> 4.1.3'

然后

bundle install

它显示了我

An error occurred while installing sassc (2.4.0), and Bundler cannot continue.
Make sure that `gem install sassc -v '2.4.0' --source 'https://rubygems.org/'`
succeeds before bundling.

In Gemfile:
  sass-rails was resolved to 6.0.0, which depends on
    sassc-rails was resolved to 2.1.2, which depends on
      sassc

我建议您避免使用Ruby 2.3.3。只需2.4.0或更高版本即可。

您的错误是在2.3.3中使用Rails 5。它根本行不通-存在很多冲突，尤其是与nokori，sqlite3，sass和tzinfo依赖项有关。将Rails降级到4.2.8或4.2.11。

我还可以知道哪个操作系统吗？如果是Windows，请避免使用Railsinstaller-这全都坏了。改用Rubyinstaller + Devkit-可能会有一些有关sql-adapter的弹出式窗口，您可以在Gemfile中使用以下方法进行修复：

gem 'sqlite3', platforms: [:mingw, :mswin, :x64_mingw, :jruby]
