从命令行使用 python,我执行以下命令:
driver = webdriver.Firefox()
driver.get('http://amazon.com/mp3')
el = driver.find_element_by_link_text('MP3 Downloads : MP3 Songs')
el.click()
Traceback (most recent call last):

selenium.common.exceptions.WebDriverException: Message: u'current is undefined'
我不知道“当前”是什么......我在另一台机器上运行它,错误变成了
...Message u'l is undefined'
有什么建议么?顺便说一句,这只发生在 Firefox 上的 Windows 上。
