Uncaught TypeError: Object #<Object> has no method 'browserCompatibleDocumentParser'

I have installed this gem and I get in my console:

```
Uncaught TypeError: Object # has no method 'browserCompatibleDocumentParser'
```

This is my form:

```
<%= form_tag posts_path, :method => :get, :class => "search_nav", turboform: true do %>
#
#
<% end %>
```

I have installed turbolinks last version and this gem from github.

I have checked with simple_form and form_for and I get the same behavior

What am I doing wrong?

Thank you!
