Ruby on rails 3.2 保存和打开页面（capybara/launchy）在项目中停止工作-错误

尝试调试在合并Rails两个项目时无法使用的部分规范

我已经删除了我的Gemfile.lock并从头开始重新安装，我已经在特定的gems上运行了bundle更新，以及所有这些，但是当我尝试在我的请求规范中使用时，遇到了一个错误

保存并打开页面

尝试从it块内部调用

保存和打开页面

：

因此，不是：

it { should have_error_message('Invalid') }

save_and_open_page

试试这个：

it { should have_error_message('Invalid'); save_and_open_page }

---

今晚为我修复了它

你能把代码发布到你调用它的地方吗？值得知道的是，如果你想在打开的页面上添加CSS样式，你必须添加

Capybara.asset\u host=”http://localhost:3000“

在spec\u helper.rb中。见：

it { should have_error_message('Invalid'); save_and_open_page }
