ruby-on-rails - 无法加载此类文件 -- autoprefixer-rails (LoadError) | 导轨 5

Question

几天来，我不知道原因，但每次我想开始或做一个动作并且gem 'bootstrap', git: ' https://github.com/twbs/bootstrap-rubygem'我的应用程序 rails 5 上安装了 boostrap ( ) 时，它总是给我同样的错误： /Users/Admin/.rvm/gems/ruby-2.5.3/bundler/gems/bootstrap-rubygem-2f5416832341/lib/bootstrap/engine.rb:3:in 'require': cannot load such file -- autoprefixer-rails (LoadError)

我已经尝试多次卸载所有内容（rails + all gems），但仍然无法正常工作。

完整的错误信息：

无论命令如何，都会出现此消息：rails db:migrate, rails s, rails c, 等等...

编辑：

我也尝试了该命令gem pristine --all，但它没有改变任何东西，我仍然有这个错误。

你的 Gemfile 应该是：

source "https://rubygems.org"
gem "singularitygs", "~>1.4"
gem "autoprefixer-rails", "~>5.1.0"

然后运行bundle install看看有没有帮助...
