ruby-on-rails - 使用 webpack 将 Rails 应用程序部署到 heroku

Question

我用 this template 创建了我的 rails 其中包括 webpack。但我仍然在 app/assets/javascript 中编写我的 javascript 代码。现在我正在尝试将我的应用程序部署到 heroku，但它一直失败。我得到这个错误

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': can't find executable webpack for gem webpacker (Gem::Exception)

主要错误似乎是“无法为 gem webpacker 找到可执行的 webpack”。我不知道如何解决它。这是我的 gemfile
