I came across this problem lately.
You should upgrade to capybara v1.0.1 to have a correct selenium webdriver.

To be sure I added:

I couldn't get it to work with Firefox 10 on Ubuntu. Switching to Chrome helped.

Install Chrome Driver.
安装Chrome 驱动程序。
spec_helper.rb:
spec_helper.rb：
Capybara.register_driver :selenium_chrome do |app|

end
In your spec:

For anybody experiencing this with Firefox 12, the current selenium webdriver (2.21) doesn't support FF12. The only solution I have found is to continue using Firefox is to downgrade Firefox, until selenium-webdriver is updated with FF12 support.
对于使用 Firefox 12 遇到此问题的任何人，当前的 selenium webdriver (2.21) 不支持 FF12。我发现的唯一解决方案是继续使用 Firefox 是降级 Firefox，直到 selenium-webdriver 更新为 FF12 支持。
This can be done using synaptic package manager by selecting the Firefox package, and clicking Package menu > Force Version > select an earlier version. Then apply changes.
这可以使用突触包管理器完成，方法是选择 Firefox 包，然后单击包菜单 > 强制版本 > 选择较早的版本。然后应用更改。
If you don't have synaptic, you can install it with apt-get install synaptic.
如果你没有synaptic，你可以用apt-get install synaptic 安装它。
Update: Firefox 12 support was added in 2.22 and FF13 support was added in 2.23
更新：Firefox 12 支持已在 2.22 中添加，FF13 支持已在 2.23 中添加

I was getting this error because the specs were being run on a headless server. This meant there was no display for the browser to render onto.
我收到此错误是因为规范是在无头服务器上运行的。这意味着浏览器没有显示可以渲染。
This articlesuggests using a virtual X server (X Virtual Framebuffer). This allows the browser to render in a virtual display.
本文建议使用虚拟 X 服务器（X Virtual Framebuffer）。这允许浏览器在虚拟显示中呈现。
Install like so:
像这样安装：
sudo apt-get install xvfb
sudo apt-get install x11-xkb-utils
sudo apt-get install xfonts-100dpi xfonts-75dpi xfonts-scalable xfonts-cyrillic
Then run the specs with the command xvfb-runin front.
然后使用xvfb-run前面的命令运行规范。
xvfb-run bundle exec rake spec:features
This was the SO answerthat lead me to the above article. It also gives an alternative means to use Xvfb.

I had the same problem, updating the selenium-webdriverdid not help (it was the most current version available already).
我遇到了同样的问题，更新selenium-webdriver没有帮助（它已经是可用的最新版本）。
It turns out, that I tried to run my script from an SSH session, and $DISPLAYwas not set.
事实证明，我试图从 SSH 会话运行我的脚本，$DISPLAY但没有设置。
The problem was fixed with:
问题已解决：
export DISPLAY=:0
before starting my Ruby script from the SSH session (use echo $DISPLAYin a terminal on the X session to find out what you need to put into this variable).
在从 SSH 会话启动我的 Ruby 脚本之前（echo $DISPLAY在 X 会话的终端中使用以找出需要放入此变量的内容）。

Adding the 'launchy' gem to my application's Gemfile worked with FF13.0, Capybara & Selenium v1.8.24.

This is only a reiteration of what everyone was saying above. I checked my gemfile and made sure that the 'selenium-webdriver' didn't have any limits on it then ran a 'bundle update' and it worked.
这只是对上面每个人所说的话的重申。我检查了我的 gemfile 并确保“selenium-webdriver”没有任何限制，然后运行“捆绑更新”并且它起作用了。
