语法错误，意外的keyword_ensure，期待输入结束

= simple_form_for @recipe, html: { multipart: true } do |f|
  - if @recipe.errors.any?
    #errors
      %p
        = @recipe.errors.count
          Prevented this recipe from saving
      %ul
        - @recipe.errors.full_messages.each do|msg|
          %li= msg
  .panel-body
    = f.input :title, input_html: { class:  'form-control' }
    = f.input :description, input_html: { class: 'form-control' }

  = f.button :submit, class: "btn btn-primary"

Answer 1

错误是由行

引起的

= @recipe.errors.count
  Prevented this recipe from saving

这些行中的第二行被解析为传递给方法的块，即使它不是。然后Haml插入end，最终导致您看到额外的end错误。

修复只是缩进相同的行：

= @recipe.errors.count
Prevented this recipe from saving

或许你可以在这里使用interpolation：

#{@recipe.errors.count} Prevented this recipe from saving

Answer 2

- if @recipe.errors.any?之后的行需要缩进一步。

= simple_form_for @recipe, html: { multipart: true } do |f|
  - if @recipe.errors.any?
    %p
      = @recipe.errors.count
        Prevented this recipe from saving
    %ul
      - @recipe.errors.full_messages.each do|msg|
        %li= msg
  .panel-body
    = f.input :title, input_html: { class:  'form-control' }
    = f.input :description, input_html: { class: 'form-control' }

  = f.button :submit, class: "btn btn-primary"
