迁移项目到Rails7，遇到一下问题：

undefined method `javascript_pack_tag'
<%= javascript_pack_tag 'application', 'data-turbo-track': 'reload' %>

根源： javascript_pack_tag is a Webpacker-specific method, so unless you're using Webpacker, you can't use it.

Rails中webpacker被 importmapped Hotwire取代

正确的做法是

    <%= javascript_importmap_tags %>
