尝试使用 Jekyll-assets gem 构建 Jekyll 站点时，我注意到尽管在 jekyll 服务命令上使用了 --watch 标志，但我的更改并未自动重新生成。每次我想查看浏览器中的变化时，都必须停止服务器，这是一个非常令人头疼的问题，所以我尝试解决这个问题，过了一段时间后，我了解到 Vagrant 中的 jekyllserve --watch 命令不会自动重新生成，我使用了该命令。正在使用。
为了避免这个头痛，我尝试在 Vagrant 和 jekyllserve --watch 之外安装必要的依赖项，但得到以下结果:

我尝试过用谷歌搜索这个问题，但我对网络开发还很陌生，而且有点迷失。
最佳答案
我也遇到过这个问题。看起来它是最新 Jekyll 1.4.2 版本中的一个错误。修复方法是卸载 Jekyll 1.4.2 并安装稳定版本，据我所知，这是 1.2.1
按照以下命令卸载 Jekyll 并重新安装 Jekyll 1.2.1
~ $ gem uninstall jekyll
~ $ gem install jekyll --version(="1.2.1")
运行gem install jekyll -v 1.2.1也可以工作
关于vagrant - jekyllserve --watch 命令在 vagrant 之外引发错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/21085935/
