我正在尝试将我的 Rails 应用程序部署到 heroku，但推送到 heroku 被拒绝，原因是:“Sprockets::FileNotFound:找不到类型为‘application/javascript’的文件‘jquery’”。 I've also attached a screenshot of the error

这是我的 gemfile:

source 'https://rubygems.org'

git_source(:github) do |repo_name|
  repo_name = "#{repo_name}/#{repo_name}" unless repo_name.include?("/")
  "https://github.com/#{repo_name}.git"
end

我的 application.js 看起来像这样

//= require jquery
//= require jquery_ujs
//= require jquery-ui
//= require tether
//= require bootstrap-sprockets
//= require rails-ujs
//= require turbolinks
//= require_tree 

我的 application.scss 看起来像这样:

 *= require jquery-ui
 *= require_tree .
 *= require_self
 */
 @import "bootstrap";

该应用程序在本地运行良好，但我似乎无法推送到 heroku。我已经尝试过 rake assets:precompile 并在推送到 heroku 之前提交更改，但仍然没有成功。

最佳答案

移除 gems jquery-rails, jquery-ui-rails，Rails 5.1 默认使用 rails-ujs 而不是使用 jquery。使用 yarn 安装 jquery - yarn add jquery。 Yarn
