Since .erb is by definition "embedded ruby", you can embed every ruby code between: <%=and the other: %>, typically all written in one line. In addition, ruby one-line comments start always with #, so the <%=# Comment %>style matches perfectly with both pure-ruby and erb styles for one-line comments.
由于 .erb 根据定义是“嵌入式 ruby”，您可以在:<%=和另一个:之间嵌入每个 ruby 代码%>，通常都写在一行中。此外，ruby 单行注释总是以 开头#，因此该<%=# Comment %>样式与单行注释的纯 ruby 和 erb 样式完美匹配。

In my text editor, i run command + /(sublime-text shortcut). It will be like this.
在我的文本编辑器中，我运行command + /（sublime-text 快捷方式）。它会是这样的。
<%
=begin%>
Here is the comment
<%
=end%>
It doesn't look simply, but it works.
它看起来并不简单，但确实有效。
