我正在将我的应用升级到ruby 2.6.5，似乎是链轮4.0.2导致了这个问题。我找到的大多数答案都是降级到链轮3.7.2（我在本地使用），但是当在Heroku推送过程中编译资产时，我得到了以下错误：

remote:        NoMethodError: undefined method `start_with?' for #<Regexp:0x00005582ab94a790>
remote:        /tmp/build_f56a8b75/vendor/bundle/ruby/2.6.0/gems/sprockets-4.0.2/lib/sprockets/uri_utils.rb:78:in `valid_asset_uri?'

我已将config/initializers/assets.rb修改为：

# Rails.application.config.assets.precompile << /\.(?:svg|eot|woff|ttf)\z/
Rails.application.config.assets.precompile << ["*.svg", "*.eot", "*.woff", "*.ttf"]

但是错误仍然发生。有什么办法可以解决这个问题吗？
