【问题描述】：

我目前正在开发一个通过 webpacker 安装了 Vue 的 Rails 5.2 应用程序。但是，我没有做任何造型。我只是设置身份验证。当我转到users/sign_out 时，出现以下错误。

ActionController::RoutingError（没有路由匹配 [GET] “/javascripts/application.js”）：

我在/javascripts/application.js 中确实有一个文件，其中包含以下代码：

// This is a manifest file that'll be compiled into application.js, which will include all the files
// listed below.
//
// Any JavaScript/Coffee file within this directory, lib/assets/javascripts, or any plugin's
// vendor/assets/javascripts directory can be referenced here using a relative path.
//
// It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the
// compiled file. JavaScript code in this file should be added after the last require_* statement.
//
// Read Sprockets README (https://github.com/rails/sprockets#sprockets-directives) for details
// about supported directives.
//
//= require rails-ujs
//= require activestorage
//= require_tree .

不确定问题出在哪里。

【解决方案1】：

这是旧的，但对于遇到此问题的任何人，您需要更改： <%= javascript_include_tag 'application' %> 到 <%= javascript_pack_tag 'application' %>

【讨论】：

你能解释一下这有什么变化吗？更改后我收到undefined method 'javascript_pack_tag'
@Smartens 如果您已升级到 Rails 6，这将“激活”您的 webpack 安装并指示 rails 使用 webpack 而不是资产管道
