Capybara 与 Selenium 抛出 Net::ReadTimeout: Net::ReadTimeout

Question

我今天从假期回来，我的水豚和硒动力测试抛出了这个错误：

Net::ReadTimeout: Net::ReadTimeout

基本上，在我离开之前没有任何改变，这些测试只适用于其他人（即其他计算机）。为了让它们再次工作，我升级了 Firefox，我在 /etc/hosts 中添加了一些主机名以删除 DNS 查找，升级了所有 gem（包括 capybara）。我的想法不多了。

环境是 OS X 10.9.5。为了以防万一，我重新启动了几次。我正在运行 Ruby 2.1.5、Rails 3.2.21、MiniTest 4.7.5。

还有其他想法可以尝试吗？

Answer 1

gem install 'eventmachine'  -v 1.0.3

如果您有 1.0.3 以外的版本，请卸载它并安装指定的版本。

可能是这样，这解决了问题。
