使用webpack将Rails应用程序部署到heroku

Question

我用包含webpack的this template创建了我的rails。但我仍然在app / assets / javascript中编写了我的javascript代码。现在我正在尝试将我的应用程序部署到heroku并且它一直在失败。我收到这个错误

remote：/tmp/build_6f0656280cbbda40c5832ccb79fc1783/vendor/bundle/ruby/2.3.0/gems/bundler-1.15.2/lib/bundler/rubygems_integration.rb:432:in“block in replace_bin_path”：找不到gem的可执行webpack webpacker（Gem :: Exception）

主要错误似乎是“无法找到gem webpacker的可执行webpack”。我不知道如何解决它。这是我的宝石文件
