ruby-on-rails - 异常消息 : no such file to load in rails application

Question

我在 Rails 应用程序的 test 下包含了 test_helper.rb。我什至包括 在 test->unit 下的 test.rb 文件中 require 'test_helper'。当我在 RubyMine 中为应用程序运行所有测试时，出现以下错误:

我有所有 RubyMine 3.2、ruby 1.9.2p290 和 Rails 3.1.0 的最新版本。

我错过了什么？ 谢谢!

test_helper.rb 位于测试目录中。您正在从根目录运行测试，这意味着文件的路径是错误的。尝试从测试目录运行测试。

如果您想从根目录运行测试，则必须将其更改为 require File.join(File.dirname(__FILE__), '..', 'test_helper.rb')，其中 FILE 是包含此行(您的测试用例)的文件的路径，其余是 test_helper.rb 的路径，相对于该文件。这样，您从哪里运行测试就无关紧要了。
