Question

我正在尝试在我的Rails项目中包含requirejs，并且在尝试使用它时遇到错误。我通过遵循以下教程来尝试使用require js：https://gist.github.com/eoinkelly/5778004，一切似乎都很好，但是当我尝试require时，它开始给我错误。

在我的gemfile中，我有gem 'requirejs-rails'，并且已运行bundle install

我的 application.js 看起来像这样

// = require require
require(['jquery'], function($) {
    'use strict';

    // Your awesome javascript goes here!

    // **********************************
    // This is just some guff to help you prove that everything works.
    // You can and should delete this once everything works.
    console.log('Successfully loaded jQuery version: ' + $('body').jquery);
    if (typeof $.rails === 'object') {
        console.log('The $ object seems to have been decorated by Rails UJS successfully. Good job!');
    }
    else {
        console.log('Uh-oh, it seems that $ has not been decorated by Rails UJS. You might want to check this.');
    }
    // **********************************

});

它显示The $ object seems to have been decorated by Rails UJS successfully. Good job!，因此看起来工作正常，但是在我的js代码中，我有以下一行：

var antlr4 = require(['acolade_parser/antlr4/index.js']);

这给我一个

的错误

Failed to load resource: the server responded with a status of 404 (Not Found)

如果我删除了需求的.js部分（我认为这是正确的），我会得到

ReferenceError: Can't find variable: exports

这使我相信requirejs尚未加载。我的 application.html.erb 看起来像这样：

<!DOCTYPE html>
<html>
  <head>
    <title>ACoLaDe</title>
    <%= stylesheet_link_tag    'application', media: 'all', 'data-turbolinks-track' => true %>
    <%= requirejs_include_tag "application" %>
    <%= csrf_meta_tags %>
  </head>
  <body>
    <p class="notice"><%= notice %></p>
    <p class="alert"><%= alert %></p>
    <%= render 'partials/header' %>
    <%= yield %>
  </body>
</html>

并且您可以看到requirejs_include_tag在哪里，所以有人知道我为什么收到此错误吗？

Rails requirejs找不到变量：导出
