我有Python 2.6和Robot框架。我已经按照下面的链接安装了Selenium2Library： https://github.com/rtomac/robotframework-selenium2library 但是当我尝试运行这个例子时，它给了我下面的错误并且没有打开firefox窗口。在我的系统上执行硒与Robot Framework的例子时发生错误

ERROR: clean-python26-env]$ python testExeJS.py 
======================================================================

我很抱歉，我刚才看到您的回复。可能这会帮助你更多地理解我的问题。示例代码的链接是： `http://www.wallix.org/2011/07/26/how-to-use-robotframework-with-the-selenium-library/

和我跑步的错误是：

$ pybot myFirstTest.txt

你可以链接到你吃的例子吗？看看这个页面，我只能看到[https://github.com/rtomac/robotframework-selenium2library/blob/master/demo/rundemo.py](https://github.com/rtomac/robotframework-selenium2library/blob/ master/demo/rundemo.py） – theheadofabroom 2013-02-16 10:05:02

对不起，我刚刚看到你的评论。可能这会帮助你更好地理解我的问题： – user1512496 2013-02-18 15:22:31

请参阅下面的答案，并留下评论，如果它不能解决您的问题 – theheadofabroom 2013-02-23 09:30:31

好了，所以在这里我要注释日志，以便希望你可以看到如何阅读和调试从它的未来。我对任何不准确之处表示歉意，因为我用Selenium2Library＃m的：

$ pybot myFirstTest.txt 
============================================================================== 
myFirstTest :: This is your first test           
============================================================================== 
[ WARN ] Keyword 'Capture Page Screenshot' could not be run on failure: No browser is open

好了，所以这是你的第一个线索 - 硒正试图采取截图，但没有看到一个浏览器中打开 - 你，你看到一个浏览器打开？它是否打开正确的页面？

Go To Google Page [Documentation] Go to google page and search som... | FAIL | 
WebDriverException: Message: 'The browser appears to have exited before we could connect. The output was: Error: no display specified\n'

因此，这里的下一个线索 - The browser appears to have exited before we could connect. The output was: Error: no display specified - 所以这点的问题是，你正在运行无头，并SeleniumLibrary希望找到一个显示器（请纠正我，如果我错了），所以你可能需要要创建一个，这比听起来要容易得多 - 您需要安装PyVirtualDisplay，然后从robotframework安装 - 在使用SeleniumLibrary之前尝试使用| Library | pyvirtualdisplay.smartdisplay.SmartDisplay |。

------------------------------------------------------------------------------ 
[ WARN ] Keyword 'Capture Page Screenshot' could not be run on failure: No browser is open

这又是第一条线索。

Open Selenium Page [Documentation] TestCase for open Selenium page | FAIL | 
No browser is open

这是因为较早的问题。

------------------------------------------------------------------------------ 
myFirstTest :: This is your first test        | FAIL | 
2 critical tests, 0 passed, 2 failed 
2 tests total, 0 passed, 2 failed
