第一个报错问题
'geckodriver' executable needs to be in PATH
1.1如果启动浏览器过程中报如下错误：
Traceback (most recent call last):
File "", line 1, in <module>
File "D:\test\python3\lib\site-packages\selenium\webdriver\firefox\webdriver.py", line 145, in __init__
self.service.start()
File "D:\test\python3\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.
1.2这个是因为最新的selenium3.0启动firefox需要geckodriver.exe这个驱动文件。
1.3下载之后，配置到环境变量path下(可以直接放python根目录)
第二个报错问题
Expected browser binary location, but unable to find binary in default location
1.1如果启动浏览器过程中报如下错误：
Traceback (most recent call last):
File "", line 1, in <module>
File "D:\test\python3\lib\site-packages\selenium\webdriver\firefox\webdriver.py", line 155, in __init__
keep_alive=True)
File "D:\test\python3\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 92, in __init__
self.start_session(desired_capabilities, browser_profile)
File "D:\test\python3\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 179, in start_session
response = self.execute(Command.NEW_SESSION, capabilities)
File "D:\test\python3\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 238, in execute
self.error_handler.check_response(response)
File "D:\test\python3\lib\site-packages\selenium\webdriver\remote\errorhandler.py", line 193, in check_response
raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: Expected browser binary location, but unable to find binary in default location,
no 'moz:firefoxOptions.binary' capability provided, and no binary flag set on the command line.
1.2这个是因为firefox.exe这个文件也需要配置到环境变量path下
1.3这个路径就是安装完firefox后，找到firefox.exe这个文件的地址，加到path下
第三个报错问题
Unsupported Marionette protocol version 2, required 3
1.1如果启动浏览器过程中出现如下错误：
Traceback (most recent call last):
File "", line 1, in <module>
File "D:\test\python3\lib\site-packages\selenium\webdriver\firefox\webdriver.py", line 155, in __init__
keep_alive=True)
File "D:\test\python3\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 92, in __init__
self.start_session(desired_capabilities, browser_profile)
File "D:\test\python3\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 179, in start_session
response = self.execute(Command.NEW_SESSION, capabilities)
File "D:\test\python3\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 238, in execute
self.error_handler.check_response(response)
File "D:\test\python3\lib\site-packages\selenium\webdriver\remote\errorhandler.py", line 193, in check_response
raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.WebDriverException: Message: Unsupported Marionette protocol version 2, required 3
1.2这个错误原因是firefox版本过低了，最新的selenium3.0版本支持firefox47以上的版本，升级版本就可以了
第四个报错问题
WebDriverException: Message: newSession
1.1Traceback (most recent call last)：
File “D:\test\python3\lib\site-packages\selenium\webdriver\firefox\\webdriver.py”, line 170, in init

1.2下载最新的geckodriver.exe 然后把它放到python的安装目录下
