webkit_server找不到可执行文件
问题描述：
我正在使用Capybara来测试我的Rails应用程序。webkit_server找不到可执行文件
我需要测试一些JavaScript，所以我设置了webkit来测试这些页面（不记得所有的步骤，它在几个月前）。这里有一个这样的规格从几个月前，很好的工作：
describe "user fills in form", js: true, driver: :webkit do
...
end
该规范执行并通过就好。
我做了一个新的规范，有这个天赋：
describe "check player", js: true, driver: :webkit do
...
end
而且我得到这个错误：

奇怪的是，如果我跑所有的规格为我的应用程序中，第一个（与webkit驱动程序）的作品。这只是更新的规范抛出这个错误。
