我尝试使用新添加的引导程序部署我的 rails 应用程序，但我的应用程序中的很多视图都丢失了。

这是我在部署到 Heroku 时遇到的一些错误

我也认为这可能与它有关。运行heroku run rake db命令时出现此错误

它不是错误，而是警告。这表示您有 Rails 4.0 不再支持的插件。

看起来您可能正在尝试使用 SASS 文件中的 ruby​​asset_path 函数来指示图标精灵图像的来源。

尝试使用绝对网址，即“/assets/sprite_image.png”

警告是不相关的，它是导致问题的 SASS 编译器崩溃。

您使用的是 bootstrap-sass 还是 sass？跟踪似乎表明 sass 正在将您的 css 解析为 scss。尝试禁用 sass：

group :assets do
    # gem 'sass-rails',   '~> 3.1.5'
    gem 'coffee-rails', '~> 3.1.1'
    gem 'uglifier', '>= 1.0.3'
end

如果这不起作用，那么css中可能确实存在错误。

编辑：弃用警告似乎与我无关。
