当我运行测试时，控制器失败，声称它找不到任何视图/类别/new.html.erb 文件。这是失败：

这是我的完整测试堆栈跟踪。我认为这可能是 execjs 的问题，或者与我的 javascript 在我的应用程序上的加载方式有关。这个应用程序几乎是我刚开始的基本玩具应用程序。

正如你在这一行看到的：
ActionView::Template::Error: No such file or directory @ unlink_internal - C:/Users/Javi/AppData/Local/Temp/execjs201504
29-7216-9o5jujjson
有点奇怪，不知道是什么意思。我去了 C:/Users/Javi 目录，但找不到任何 AppData 文件夹...不知道为什么它不在我的系统上。
这是我的宝石文件：
source 'https://rubygems.org'

end

这是我的 application.html.erb
<!DOCTYPE html>
<html>
<head>
<title>MinitestApp</title>
<%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track' => true %>
<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
<%= csrf_meta_tags %>
</head>
<body>
<%= yield %>
</body>
</html>
错误消息说错误发生在第 6 行：
<%= javascript_include_tag 'application', 'data-turbolinks-track' => true %>
所以这让我相信我的javascript没有正确加载......
我正在使用 Minitest，这是我的控制器测试：
require "test_helper"
class CategoriesControllerTest < ActionController::TestCase
def test_new
get :new
assert_response :success
end
end
我还创建了一个 new.html.erb 视图，除了一些虚拟文本外，它大部分是空白的：
This is my new file! #This is inside my views/categories/new.html.erb
这是我的控制器：
class CategoriesController < ApplicationController
def new
end
end
当我打开 rails 服务器并导航到我的根/类别/新路由时，我收到以下错误消息：
Errno::ENOENT in Categories#new
Showing c:/Users/Javi/desktop/rails_projects/testing_basics/app/views/layouts/application.html.erb where line #6 raised:

Rails.root: c:/Users/Javi/desktop/rails_projects/testing_basics
有人可以帮我解决这个问题吗？我已经坚持了整整2天。我已尝试降级 execjs gem 版本，但仍然出现错误。我也从头开始重新启动并在同一个地方得到同样的错误。不知道现在还能做什么...
