javascript - 即使包含 jQuery，Rails 也看不到 .tooltip 方法

Question

我正在开发一个新的 Rails 项目并尝试集成一个主题。但是，主题在其 .js 文件中使用 .tooltip，Rails 给出以下错误:

Uncaught TypeError: $(...).tooltip is not a function

这是我的 app/assets/javascripts/application.js 文件:

//= require jquery
//= require jquery_ujs
//= require dataTables/jquery.dataTables
//= require activestorage
//= require theme/inspinia.js
//= require theme/metisMenu.js
//= require theme/jquery.slimscroll.min.js

它看起来与我之前拥有的 Rails 应用程序非常相似。

这是Gemfile:

source 'https://rubygems.org'
git_source(:github) { |repo| "https://github.com/#{repo}.git" }

ruby '2.5.1'

gem 'jquery-ui-rails'

# Used for server-side processing of datatables.
gem 'jquery-datatables-rails'
gem 'ajax-datatables-rails'

我在这里的其他帖子中读到，这通常是由 jquery 被多次调用引起的，但我无法确定这是在哪里发生的。如果我尝试渲染空白页面，我仍然会收到错误，因此我不确定是 HTML 中的任何内容导致了该错误。我一定是遗漏了某些东西，或者某些东西的顺序错误。

如果我从 app/assets/javascripts/application.js 文件中删除 theme/inspinia.js，那么它就不再出现。但是，如果我手动调用它，我仍然会收到错误。这是在 app/assets/javascripts/theme/inspinia.js 文件中调用它的位置:

$('.tooltip-demo').tooltip({
    selector: "[data-toggle=tooltip]",
    container: "body"
});

您没有在项目中加载 jquery ui。在 inspina.js 之前加载 jquery-ui

//= require jquery
//= require jquery_ujs
//= require jquery-ui 
//= require dataTables/jquery.dataTables
//= require activestorage
//= require theme/inspinia.js
//= require theme/metisMenu.js
