The problem lies inside the html code:
问题出在 html 代码中：
<div>
<form>
<div>
</div>
</div>
<input type="submit" value="Verify" name="verify" id="verify" class="button">
</form>
Because there is one redundant </div>, the <input>was treat outside the form, hence capybaracause those error. After delete the redundant </div>, everything works fine.
因为有一个多余的</div>，<input>被处理在表格之外，从而capybara导致那些错误。删除冗余后</div>，一切正常。

Try adding js: truein the describe. This happens when you do not have a form that contains the button.
尝试js: true在describe. 当您没有包含按钮的表单时会发生这种情况。

Did you try "doubling up" the CSS selectors? This has been my go-to mechanism since capybara-2.4.3
您是否尝试过“加倍”CSS 选择器？自 capybara-2.4.3 以来，这一直是我的首选机制
find("#verify").find("[name=verify]").click
any other attribute in addition to the #id-vale should do the trick, e.g
除了#id-vale 之外的任何其他属性都应该起作用，例如
find("#verify").find(".button]").click

If you have an ID for an element, just use @bonzofenix's approach but make it a bit more simple:
如果你有一个元素的 ID，只需使用@bonzofenix 的方法，但让它更简单一点：
within 'form' do
find('#verify').click
end
within 'form' do
find('#verify').click
end
