ruby on rails升级资产预编译失败

Posted 2021-03-31

我有一个rails 4.2应用程序我正在从3.2升级。资产预备有问题，但我不确定我缺少什么。

#Gemfile
gem 'rails', '~> 4.2.7.1'
ruby "2.3.3"

gem 'jquery-rails', '2.1.4'
gem 'jquery-ui-rails', '4.2.1'
gem 'activeadmin'
gem 'sprockets-rails', '2.3.3

这是active_admin.js

//= require jquery
//= require jquery_ujs
//= require jquery-ui
//= require select2
//= require active_admin/base
//= require best_in_place
//= require best_in_place.jquery-ui
//= require activeadmin-sortable

资产预编译在此失败

我读到的所有问题都说运行bundle install并确保gem文件在你的Gemfile中。

答案

很难说在不了解更多配置的情况下发生了什么，但这可能是一个加载问题。 jquery-rails将实际的.js文件放在vendor/assets/javascripts中，无论出于何种原因，这些文件可能不在您的加载路径中。您可以尝试两件事：

首先尝试运行gem附带的生成器，看它是否修复了manifest文件中的路径：

rails generate jquery:install #--ui to enable jQuery UI

如果这不起作用，并且不想升级jquery-rails，你可能需要做这样的事情

//= require vendor/assets/javascripts/jquery.js
//= require vendor/assets/javascripts/jquery_ujs.js
//= require vendor/assets/javascripts/jquery-ui.js

如果我是你，我会升级
