Question

我正要在视图中添加index.png并收到此错误。我已将文件放入app/assets/images/index.png

Sprockets::Rails::Helper::AssetNotPrecompiled in Maps#new

Showing /home/sumin/sumin/project/tourism-board/app/views/maps/new.html.slim where line #9 raised:

Asset was not declared to be precompiled in production.
Add `Rails.application.config.assets.precompile += %w( index.png )` to `config/initializers/assets.rb` and restart your server

Extracted source (around line #33):
      url_for establishment.avatar.variant(resize: ' 10x10 ')
    else
      image_url 'index.png'
    end
  end
end

Answer 1

我不知道为什么，但是我通过将资产名称从index.png更改为marker.png来解决了这个问题。我认为不应该是index.png。名称为index

的东西很有趣

开发错误：未声明资产已在生产中进行预编译
