Question

我在Windows上遇到过Jekyll的一些重大问题。我终于开始工作了，所以我跑了

jekyll build

然后

jekyll serve --watch

然后我得到以下错误，有人可以帮忙吗？

完整错误是：

Answer 1

我遇到了同样的问题。通过设置“Windows目录监视器”非常简单地解决了这个问题。

gem install wdm

并在Gemfile中包含此行：

gem 'wdm'

祝你好运！

Answer 2

您似乎在listen gem（1.3.1）的旧版本上运行。尝试更新到最新版本（2.4.0）

$ gem update listen

在Gemfile：

中

require 'rbconfig'

gem 'listen', '~> 2.4'
gem 'wdm', '>= 0.1.0' if RbConfig::CONFIG['target_os'] =~ /mswin|mingw|cygwin/i

添加了 gem wdm，因为我不确定listen gem是否require it by itself，但是自述状态指出这是可选的，否则它将回退到效率较低的轮询这样做的方式。

This blog post说：

# If you get the following error with the –watch option

C:/Ruby193/lib/ruby/gems/1.9.1/gems/listen-1.3.1/lib/listen/adapter.rb:207:in `require': cannot load such file -- wdm (LoadError)

# To fix that error, open the gemfile in your jekyll project directory and add these two lines:

require 'rbconfig'
gem 'wdm', '>= 0.1.0' if RbConfig::CONFIG['target_os'] =~ /mswin|mingw/i

Ruby错误：无法加载此类文件--wdm（LoadError）
