【问题标题】：Can't push to heroku, sassc segmentation fault无法推送到heroku，sassc分段错误

【问题描述】：

我在推送到 heroku 时遇到问题，我已经尝试过其他与 预编译资产失败相关的解决方案。，例如修改 application.rb 以禁用预编译资产、运行 rake assets:precompile 并更新到rails 6.3.1 以防止 mimemagic 最近的错误。

查看heroku日志，我注意到：

tmp/build_7857ebbd/vendor/bundle/ruby/3.0.0/gems/sassc-2.4.0/lib/sassc/engine.rb:43： [BUG] 0x0000000000000000 ruby 3.0.0p0 处的分段错误 (2020-12-25 修订 95aff21468) [x86_64-linux]

【解决方案1】：

基于同一个线程，我发现这个解决方案比降级一堆宝石更合适。

把它放在你的 initializers/assets.rb 的顶部使资产能够成功编译

# config/initializers/assets.rb
Rails.application.config.assets.configure do |env|
  env.export_concurrent = false
end

仍然是 hack，但另一种选择。

【解决方案2】：

这似乎是问题133 和197 中报告的最新错误

One solution 是使用旧的 sassc 版本。特别是，我尝试过：

gem 'sassc', '~> 2.0', '>= 2.0.1'
gem 'sprockets', '~> 3.7.2'
gem 'sass-rails', '~> 5.1.0 ' 
gem 'concurrent-ruby',  '~>1.1.5'

效果很好。所有可用版本均为listed here
