使用插件编译Jekyll项目时，Jekyll_lunr_js_search总是在Windows中遇到以下错误。但是，它在gitlabci上编译。
依赖关系错误：yikes！看来您没有d：/myproject/_plugins/lunrjs/jekyll_lunr_js_search.rb或已安装的依赖项之一。为了使用当前配置的Jekyll，您需要安装此GEM。Ruby的完整错误消息是："无法加载此类文件-V8"，如果您遇到麻烦，您可以在https://jekyllrb.com/help/上找到有用的资源！
使用gem install jekyll-lunr-js-search以下错误：

注意：我已经安装了Python V2和V3，正常工作。使用py -2输出测试的python shell如下：

如果您查看lib目录，您会发现Ruby文件是jekyll-lunr-js-search.rb而不是jekyll_lunr_js_search.rb。此外，它也可以作为RubyGem软件包。
只需将GEM添加到您的Gemfile中的:jekyll_plugins组，运行bundle install并继续使用Jekyll构建/服务。
