我正在运行Ubunut 13.04和Rubymine 6.0.3
我的问题是Launchy gem没有打开我的浏览器。
我对Capybara save_and_open_page进行了调查并执行了
Launchy.open(file_name,{debug:true})
保存html页面，但浏览器无法启动。
这是调试结果

奇怪的是它看起来像是找到了firefox，但是我的默认浏览器是chrome
$ sudo update-alternatives --config x-www-browser
返回
There are 2 choices for the alternative x-www-browser (providing /usr/bin/x-www-browser).
Selection Path Priority Status
------------------------------------------------------------
* 0 /usr/bin/google-chrome-stable 200 auto mode
1 /usr/bin/firefox 40 manual mode
2 /usr/bin/google-chrome-stable 200 manual mode
另一个奇怪的事情，它看起来像firefox正在运行（在系统监视器中我看到了进程） 但是我没有任何firefox窗口，当我尝试启动firefox时出现错误
Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system
这里有一些问题
a）我希望Launchy使用chrome而不是firefox
b）Firefox进程似乎没有正确启动（但是我可以正常启动firefox）
