更新到Ubuntu 22.04后，我无法使用Jekyll。
bundle exec jekyll serve产生这个错误:

有什么建议如何解决这个问题吗?
jekyll repo: https://github.com/schmidb/TurtleTrafo
可能是Ruby 3的问题，参见:
- https://talk.jekyllrb.com/t/error-no-implicit-conversion-of-hash-into-integer/5890/7
- https://github.com/envygeeks/pathutil/issues/4
第二个链接建议降级到Ruby/Bundler 2.7
在这个线程中还有一个有趣的信息:
在4月26日Jekyll v3.9.2最终删除了Jekyll对pathutil的主要依赖。现在Github Pages已经更新到Jekyll的那个版本(参见https://github.com/github/pages-gem/pull/833)，这个问题应该不会再影响Github Pages或Jekyll了。
Gemfile。锁显示Jekyll 3.9.2，所以问题应该已经解决了。
