selenium_webdriver 驱动不了浏览器问题
最近很多同学，自己在学习selenium工具时，碰到一个最多的问题就是为什么我创建了一个浏览器实例，driver.get(url)时，却打不开浏览器，或者就算打开了无法输入相应的URL，这是为什么呢？
笔者最近在自学selenium工具时，也碰到了这些问题，最后发现是驱动版本的问题，因为webdriver 在启用我们指定的浏览器 Chrome/Firefox/I e时,需要调用相应的驱动，不同的浏览器版本对应的驱动不一样，有些驱动只支持哪几个浏览器相关版本，例如以Chrome为例：
----------ChromeDriver v2.7 (2013-11-22)---------- Supports Chrome v30-33 Resolved issue 615: ChromeDriver doesn't work well with auto detect proxy settings [OS-Windows, Pri-0] Resolved issue 614: Implement new redirectionless /session command [Pri-0] Resolved issue 625: logging broken on windows [Pri-0] Resolved issue 573: chromedriver crashes on windows occasionally [OS-Windows, Pri-1] ----------ChromeDriver v2.6 (2013-11-04)---------- Supports Chrome v29-32 Resolved issue 599: Chromedriver failes after MacOS X Mavericks upgrade [OS-Mac, Pri-0, Type-Defect] Resolved issue 585: Return user data dir via capabilities [] ----------ChromeDriver v2.5 (2013-11-01)---------- Supports Chrome v29-32 Resolved issue 600: Support minidump for chrome crashes on Linux with a new capability minidump_path. [Pri-0] Resolved issue 569: A change in blink breaks scrolling an element into view [Pri-0] Resolved issue 554: Release notes broken [Pri-0] Resolved issue 545: hang when debugger is invoked via JS [Pri-0] ----------ChromeDriver v2.4 (2013-09-30)---------- Supports Chrome v29-32 Resolved issue 444: chromedriver sometimes hangs when launching chrome (chrome fails to bind to debug port) [Pri-0] Resolved issue 529: WebDriver clients fail when attempting to use empty chromeOption binary string [Pri-0] Resolved issue 536: remote debugging port taken during startup [Pri-0] Resolved issue 520: Some commands hangs if the target window already crashes. [] Resolved issue 519: Support JS heap snapshot [] ----------ChromeDriver v2.3 (2013-09-02)---------- Resolved issue 309: Screenshot is blank from an VM instance without an open RDC connection [Pri-1] Resolved issue 445: chromedriver crashes when port is in use [Pri-1] Resolved issue 461: TouchUp, TouchDown, and TouchMove commands [OS-All, Pri-1] Resolved issue 489: No longer using packed extension id when loading custom extensions [Pri-3] Resolved issue 491: Extension does not have its _id_ [Pri-3] Resolved issue 497: unrecognized chrome option: useExistingBrowser [Pri-3] ----------ChromeDriver v2.2 (2013-08-06)----------
以上我们可以看到，不同的ChromeDriver 支持的浏览器版本是不一样的，如果我们拿ChromeDriver v2.4 的驱动，去驱动Chrome 35或者以上的版本，可能会出现前面提到的各种问题，其他类型浏览器类似，碰到这类问题一般都是驱动引起的。
ChromeDriver 驱动下载及支持的浏览器版本号，以下链接可以找到：
