ruby - Cucumber 测试无法启动，错误为 "Display socket is taken but lock file is missing.."

Question

运行 cucumber 后

bundle exec cucumber features/emails.feature:20

我遇到了错误

Display socket is taken but lock file is missing - check the Headless troubleshooting guide (Headless::Exception) /Users/me/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/headless-2.2.0/lib/headless.rb:195:in ensure_xvfb_is_running'
/Users/me/.rbenv/versions/2.3.1/lib/ruby/gems/2.3.0/gems/headless-2.2.0/lib/headless.rb:184:in

我正在运行 MacOS 10.11.5，安装了 xquartz，第一次开始测试，我无法再次启动。有什么建议吗？

完全披露:我不知道这里发生了什么，希望有人向我解释，但是运行以下命令可以使 Xvfb 和我的测试套件正常工作:

mkdir /tmp/.X11-unix
sudo chmod 1777 /tmp/.X11-unix
sudo chown root /tmp/.X11-unix/
