Error: `require': cannot load such file -- jemoji (LoadError)

我是第一次使用jekyll。 我从这里下载了 here. When i run build and run the site using jekyll it runs well. Now I downloaded personal theme 的源代码。导航到下载的主题文件夹然后构建新主题后不起作用。我收到以下错误:

如果可能的话,请告诉我哪里做错了,哪里做错了。是否有一些规则规定我只能在本地构建一个规则?据我搜索,我尝试更改 config.yml 中的端口号,还尝试通过指定各自的配置文件来构建不同的站点。 jekyll 仍然没有构建并给出相同的错误。提前感谢您的帮助。

我也收到错误 jekyll-feed Load Error

上述问题已按照自述文件和 运行 ./scripts/install 中的说明解决。

感谢@Jordan 的帮助。
