You need to use space trimming in your non-printing tags. Like this...

<%- @variables.each do | index, value | -%>
<%= 'export ' + index.upcase %>=<%= value.upcase %>
<%= 'export ' + index.downcase %>=<%= value.downcase %>
<%- end -%>

The <%- and -%> at the start and end of the first and last lines tells Ruby not to add a line break.
