undefined method `truncate_html' for #<#<Class

[soniacaan]

Followed the instructions provided for installing this gem. But get an error message. Any idea what might be the problem?

View
<%= truncate_html(micropost.body, length: 40) %>

Error Msg
undefined method `truncate_html' for #<#<Class:

+1, facing the simillar issue, also tried inclusing "include TruncateHtmlHelper
helper_method :truncate_html" with no success.

The gem you get when you gem install truncate_html is actually not this one, but this one: https://github.com/hgmnz/truncate_html

This gem we're looking at hasn't had a commit since 2011, I think it's abandonware.

I am searching for and reviewing html truncation options.
