ruby - routing error no route matches [post] i want to resolve "/ items/new"

Routing Error
No route matches [POST] "/ items/new"

This error appears when implementing the posting function.
Resources: items, only: [: index,: new,: create] do in routes.rb
Why do I get a routing error even though I have mentioned?

class ItemsController</pre>
<pre><code>class Item</pre>
<pre><code>Rails.application.routes.draw do
  devise_for: users
  root to:'items # index'
  resources: items, only: [: index,: new,: create] do
  end
end

Thanks for your cooperation.

    In resources[POST]"/ items/new"Is not generated.

    new action is[GET]"/ items/new"But
    create action is[POST]"/ items"Will be.
    This is$rails routesYou can check it with a command.

    The HTML form_with was just not set.

    <% = form_with (model: @item, local: true) do | f |%>
