I’m running jekyll 3.7.3 on Windows 7, I’ve been getting

```

```

When trying to run the --livereload option with bundle exec jekyll serve and editing a file. I seem to think this was working fine a week ago, not sure if I maybe messed something up by updating, my gemfile adds support for wdm latest and em/pure\_ruby.

The issue could be due to:

EventMachine is not yet compatible with Ruby 2.4+ on Windows:

Thank you! What a dumb mistake, you get kind of tired looking through all the readme files, I should have checked there first before updating ruby.

I just reinstalled ruby 2.3.3, I should have checked before updating.
