原因：

Ruby版本太高，默认不支持webrick

解决办法：

https://jekyllrb.com/docs/ 

If you are using Ruby version 3.0.0 or higher, step 5 may fail. You may fix it by adding webrick to your dependencies: bundle add webrick

在启动Jekyll之前,先执行

bundle add webrick

再执行

bundle exec jekyll serve

Jekyll 运行时错误： check_for_activated_spec!

/Library/Ruby/Gems/2.6.0/gems/bundler-2.1.4/lib/bundler/runtime.rb:312:in `check_for_activated_spec!':
You have already activated i18n 1.8.3, but your Gemfile requires i18n 0.9.5.
Prepending `bundle exec` to your command may solve this. (Gem::LoadError)

​ 解决办法:

bundle update

修改 Gemfile.lock 将 i18n 配置升级为1.8.3

bundle exec jekyll serve
