Question

尝试将应用推送到heroku时出错。

 !
 !     Precompiling assets failed.
 !
 !     Push rejected, failed to compile Ruby app

当我向上滚动时，我看到以下错误：

   NoMethodError: undefined method `specificity' for [:not(.button)]:Array
   (in /tmp/build_3060eff8-6b06-48b5-8d0d-51ce090945b4/app/assets/stylesheets/foundation_and_overrides.scss)

应用程序存在了很长一段时间，我上周更新了它，没有任何问题。在这个推动中，我只有微小的变化。

我没有在foundation_and_overrides.scss中看到任何与'特异性'或：非（按钮）选择器有关的内容

在本地运行时：

rake assets:precompiled --trace

得到了同样的错误：

 ** Execute assets:precompile:primary
rake aborted!

Answer 1

@pazinjanka，你是生命的救星！我降级了，它再次像魅力一样工作。要安装3.4.5，请使用命令sudo gem install sass -v 3.4.5

Answer 2

您是否尝试在本地预编译它们？

RAILS_ENV=production bundle exec rake assets:precompile

也许你可以从错误中发布更多回溯？

你有没有更新你的宝石（Sass？），也许它可能与某些事情有关：https://github.com/sass/sass/issues/1476 不确定，只是猜测...

Answer 3

如果您已经安装了更高版本的sass。这样做：

将此添加到gemfile

<强>的Gemfile：

gem 'sass', '3.4.5'

然后运行bundle update sass
