python基础教程Python3+selenium配置常见报错解决⽅案
第⼀个坑：'geckodriver' executable needs to be in PATH
1.如果启动浏览器过程中报如下错误
Traceback (most recent call last):
File "<stdin>", 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)
2.这个是因为最新的selenium
3.0启动firefox需要这个驱动⽂件。
3.下载之后，配置到环境变量path下（可以直接放python根⽬录）
第⼆坑：Expected browser binary location, but unable to find binary in default location
1.如果启动浏览器过程中报如下错误：
Traceback (most recent call last):
不显示滚动条css
File "<stdin>", 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 = ute(Command.NEW_SESSION, capabilities)
File "D:\test\python3\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 238, in execute
taxi<_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)
no 'moz:firefoxOptions.binary' capability provided, and no binary flag set on the command line.
2.这个是因为这个⽂件也需要配置到环境变量path下。
3.这个路径就是安装完firefox后，到这个⽂件的地址，加到path下。
第三坑：Unsupported Marionette protocol version 2, required 3
1.如果启动浏览器过程中出现如下错误
Traceback (most recent call last):
File "<stdin>", 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 = ute(Command.NEW_SESSION, capabilities)
File "D:\test\python3\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 238, in execute
<_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)
python eval是什么意思on 2, required 3python入门教程 下载
2.这个错误原因是firefox版本过低了，最新的selenium
3.0版本⽀持firefox47以上的版本，升级版本就可以了
第四坑：WebDriverException: Message: newSession
1.Traceback (most recent call last):
File “D:\test\python3\lib\site-packages\selenium\webdriver\firefox\\webdriver.py”, line 170, in init
keep_alive=True)变量名的命名规则一般规定如下
File “D:\test\python3\lib\site-packages\selenium\webdriver\firefox\\webdriver.py”, line 156, in init
self.start_session(capabilities, browser_profile)
File “D:\test\python3\lib\site-packages\selenium\webdriver\firefox\\webdriver.py”, line 245, in start_session response = ute(Command.NEW_SESSION, parameters)
File “D:\test\python3\lib\site-packages\selenium\webdriver\firefox\\webdriver.py”, line 314, in execute
<_handler.check_response(response)
excel中最常用的函数
File “D:\test\python3\lib\site-packages\selenium\webdriver\firefox\\errorhandler.py”, line 242, in check_response raise exception_class(message, screen, stacktrace)
2.下载最新的 然后把它放到python的安装⽬录下
