我正在将3.0.20应用升级到4.x.这是通过从空白rails4目录开始并添加代码/测试来完成的。 由于大量的rspec测试，情况进展顺利。
当某些测试由于验证错误（预期）而失败时，我收到来自I18n的投诉，这似乎是试图将目录加载为翻译文件。

答案 0 :(得分：0)
我终于确定问题是我的I18路被我惹恼了。 我做了：
<div class="wrapper">
<header>
<nav>
<ul>
<li><a href="#">Item 1</a>
</li>
<li><a href="#">Item 2</a>
</li>
<li><a href="#">Item 3</a>
</li>
</ul>
</nav>
</header>
<div class="content">
<aside>Sidebar 1</aside>
<main>Main Content Area</main>
<aside>Sidebar 2</aside>
</div>
<footer>Footer</footer>
</div>I18n.loadpath不接受目录，而是文件。 我的意思是：
config.i18n.load_path += Dir[Rails.root.join('lib').to_s]
ID10T错误。
