如何修复“Sprockets::FileNotFound: 找不到类型为 'application/javascript' 的文件 'turbolinks'”

Question

我无法将我的代码推送到 heroku，但它可以在本地运行。 当我在终端中制作rake assets:precompile 时，我有这个答案： rake aborted! Sprockets::FileNotFound: couldn't find file 'turbolinks' with type 'application/javascript'我不想再使用 Sprockets

我试过这个：https://www.innoq.com/en/blog/rails-custom-elements-with-turbolinks-webpack/

但是当我制作时：

class ApplicationController < ActionController::Base
  include Turbolinks::Redirection
  # ...
end

我有这个来自错误控制台的错误uninitialized constant ApplicationController::Turbolinks

我的 app/javascript/packs/ 中的 application.js

import Turbolinks from 'turbolinks'
Turbolinks.start()

import '../css/application.scss'
import 'bootstrap'

Answer 1

对我来说，问题在于 application.js。创建一个全新的 Ruby on Rails 应用程序后，我的 application.js 标头如下所示：

之前

//= require turbolinks
//= require_tree .

//=require turbolinks 似乎是导致问题的原因，因为我从未安装过 turbolinks 或任何类似的东西。删除此行为我解决了这个问题：

之后

//= require_tree .
