问题似乎与：

有关

browser.div(:class => "select2-drop select2-display-none select2-with-searchbox select2-drop-active")

从HTML图片中，不是包含div元素的li。它是包含元素的兄弟div。因为它有一个id，你可以通过以下方式找到它：

browser.div(:id => "select2-drop")

然后结果是：

li_count_in_ul9 = browser.div(:id => "select2-drop").ul(:class => "select2-results").lis(:class => "select2-results-dept-0 select2-result select2-result-selectable")

从HTML共享中，可能会过度指定。你可以简单地做到：

li_count_in_ul9 = browser.div(:id => "select2-drop").lis(:class => "select2-result-selectable")
