No not the rails console!

ERB stands for Embedded Ruby!

You know when you do rails generate controller abc def

you get a file  def.html.erb

that's an ERB file, an Embedded Ruby file

The contents of that file get preprocessed , such that anything outside of <%..%>  gets outputted, and anything inside <%...%> gets executed and <%=....%> involves execution and a result outputted.

PHP has a similar concept.. PHP though also has a PHP.EXE file that you can run a file through and get the output.

I see it now, it's mentioned here 



C:\Ruby24-x64\bin>dir erb.* /s/b
C:\Ruby24-x64\bin\erb
C:\Ruby24-x64\bin\erb.cmd

C:\Ruby24-x64\bin>


C:\blah>type a.erb
<%= 5 %>
C:\blah>erb a.erb
5
C:\blah>

I suspect you're looking for "irb" -- Interactive Ruby.

No, ERB is not IRB.  ERB is called Embedded Ruby,  people often use it when they use Rails.
