脚本：（打开火狐浏览器，进入百度网页，搜索selenium）
from selenium import webdriver browser = webdriver.Firefox(); browser.get("http://www.baidu.com"); browser.find_element_by_id("kw").send_keys("selenium"); browser.find_element_by_id("su").click(); browser.quit();
执行脚本报错1：
Traceback (most recent call last): File "D:\2017\programming language\python\installPath\lib\site-packages\selenium\webdriver\common\service.py", line 74, in start stdout=self.log_file, stderr=self.log_file) File "D:\2017\programming language\python\installPath\lib\subprocess.py", line 707, in __init__ restore_signals, start_new_session) File "D:\2017\programming language\python\installPath\lib\subprocess.py", line 990, in _execute_child startupinfo) FileNotFoundError: [WinError 2] 系统找不到指定的文件。 During handling of the above exception, another exception occurred: Traceback (most recent call last): File "D:\2017\programming language\python\installPath\Scripts\baidu.py", line 3, in <module> browser = webdriver.Firefox(); File "D:\2017\programming language\python\installPath\lib\site-packages\selenium\webdriver\firefox\webdriver.py", line 142, in __init__ self.service.start() File "D:\2017\programming language\python\installPath\lib\site-packages\selenium\webdriver\common\service.py", line 81, in start os.path.basename(self.path), self.start_error_message) selenium.common.exceptions.WebDriverException: Message: ‘geckodriver‘ executable needs to be in PATH.
这里提到geckodriver驱动，selenium3.x中，firefox浏览器驱动独立，需要单独安装；
解决方法：下载geckodriver驱动，将其放入python安装路径中，确保path中已添加该路径；
再次执行脚本，报错2：
Traceback (most recent call last): File "D:\2017\programming language\python\installPath\Scripts\baidu.py", line 3, in <module> browser = webdriver.Firefox(); File "D:\2017\programming language\python\installPath\lib\site-packages\selenium\webdriver\firefox\webdriver.py", line 152, in __init__ keep_alive=True) File "D:\2017\programming language\python\installPath\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 98, in __init__ self.start_session(desired_capabilities, browser_profile) File "D:\2017\programming language\python\installPath\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 188, in start_session response = self.execute(Command.NEW_SESSION, parameters) File "D:\2017\programming language\python\installPath\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 256, in execute self.error_handler.check_response(response) File "D:\2017\programming language\python\installPath\lib\site-packages\selenium\webdriver\remote\errorhandler.py", line 194, in check_response raise exception_class(message, screen, stacktrace) selenium.common.exceptions.WebDriverException: Message: Unable to find a matching set of capabilities
解决方法：
1. 检查本机java版本，selenium3.x只支持java8版本以上，这里符合要求；
2. geckodriver版本是v0.16.1 ，firefox浏览器版本是45，卸载firefox，安装最新版本的firefox版本53；
运行脚本，可以正常执行。
python3.6.1+selenium3.0环境安装问题及解决方法
