Bootstrap过去在Rails上表现出色！现在，我遇到了一个非常奇怪的错误。
我以前使用的是Bootstrap gem的旧版本（如果我没记错的话，它是4.1.3）。但是，当我按下Rails应用程序时，Github给了我这个有关警报的提示：
在4.3.1之前的Bootstrap 4和3.4.1之前的Bootstrap 3中，XSS为 可能在工具提示或弹出式窗口数据模板属性中。欲了解更多 信息，请参阅： https://blog.getbootstrap.com/2019/02/13/bootstrap-4-3-1-and-3-4-1/
了解，这是我想的。现在，逻辑上要做的是更新我的gemfile，以使bootstrap gem依赖项语句如下所示：
gem "bootstrap", ">= 4.3.1"
足够容易。添加完后，运行bundle install，然后重新启动服务器，我得到了这个错误：
/Users/myusername/.rvm/gems/ruby-2.5.1/gems/bootsnap-1.4.4/lib/bootsnap/load_path_cache/core_ext/kernel_require.rb:22:in `require': cannot load such file -- bootstrap (LoadError)
很奇怪吧？我实际上在两种不同的情况下遇到此错误：
我该如何解决该错误？任何帮助表示赞赏！
这是我的完整堆栈跟踪记录
