问题描述
我已经通过以下链接尝试过但没有得到任何帮助：-
Cannot load Ruby EventMachine in Rails console - no such file to load
Using Live Reload with Jekyll
Unable to load the EventMachine C extension; To use the pure-ruby reactor
从上面提到的第二个问题，我了解到 --livereload 带有 jekyll v3.7+。
我的机器有以下内容：
Pkg / Cmd Versions
--------- -------------------------------------------------------------
npm -v 6.14.13
ruby -v ruby 3.0.2p107 (2021-07-07 revision 0db68f0233) [x64-mingw32]
gem -v 3.2.22
jekyll -v jekyll 4.2.0
bundle -v Bundler version 2.2.23
现在，当我执行 bundle exec jekyll serve 或 jekyll serve 时，我得到以下输出：-
PS C:\Users\Vedant\source\repos\mine\phougatv.github.io> jekyll serve

当我执行 bundle exec jekyll serve --livereload 或 jekyll serve --livereload 时，我得到：

for any additional information or backtrace.

收到上述错误后，我遵循了 Answer-1 & Answer-2，并将 gem "eventmachine" 添加到 Gemfile 但它们似乎没有解决我的问题。这些答案之一给出了错误：'require': cannot load such file -- sorted_set (LoadError)，为了解决这个问题，我做了 gem install sorted_set（SortedSet 已被删除），但随后显示了其他错误消息。在尝试了所有这些答案之后，我认为我离正确的方法还差得很远。
问题：我如何成功执行：bundle exec jekyll serve --livereload 或 jekyll serve --livereload？
解决方法
遇到了同样的问题，使用了您链接的其中一个帖子中的 this answer，至少为我解决了这个问题。不过，您可能已经尝试过了。
