今天做selenium項(xiàng)目更新，莫名其妙報(bào)了SessionNotCreatedException 錯(cuò)誤，顯示錯(cuò)誤如下：
File "D:\Program Files\Python37\lib\site-packages\selenium\webdriver\chrome\webdriver.py", line 89, in __init__
keep_alive,
File "D:\Program Files\Python37\lib\site-packages\selenium\webdriver\chromium\webdriver.py", line 112, in __init__
options=options,
File "D:\Program Files\Python37\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 286, in __init__
self.start_session(capabilities, browser_profile)
File "D:\Program Files\Python37\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 378, in start_session
response = self.execute(Command.NEW_SESSION, parameters)
File "D:\Program Files\Python37\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 440, in execute
self.error_handler.check_response(response)
File "D:\Program Files\Python37\lib\site-packages\selenium\webdriver\remote\errorhandler.py", line 245, in check_response
raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.SessionNotCreatedException: Message: session not created: Missing or invalid capabilities
(Driver info: chromedriver=73.0.3683.68 (47787ec04b6e38e22703e856e101e840b65afe72),platform=Windows NT 10.0.18363 x86_64)
顯示不是chromedriver與chrome版本不兼容問(wèn)題。后面腦回路，終于知道原因。
之前可能安裝了其它包把selenium版本更新到了4.x.x。猜測(cè)這個(gè)版本對(duì)chrome版本有最低要求。經(jīng)過(guò)升級(jí)chrome版本與chromedriver，測(cè)試了下也確實(shí)能正常。懶得去追根溯源了，解決方案：
1）安裝回selenium 3版本，目前最后一版3的版本號(hào)是3.141.0：
pip install selenium==3.141.0文章來(lái)源：http://www.zghlxwxcb.cn/news/detail-643291.html
2）升級(jí)chrome與chromedriver到較新版。記selenium4 使用services設(shè)置chromedriver路徑：文章來(lái)源地址http://www.zghlxwxcb.cn/news/detail-643291.html
from selenium.webdriver.chrome.service import Service as ChromeService
......
s = ChromeService(executable_path=driver_path)
webdriver.Chrome(service=s, options=options)到了這里，關(guān)于python 報(bào) selenium.common.exceptions.SessionNotCreatedException的文章就介紹完了。如果您還想了解更多內(nèi)容，請(qǐng)?jiān)谟疑辖撬阉鱐OY模板網(wǎng)以前的文章或繼續(xù)瀏覽下面的相關(guān)文章，希望大家以后多多支持TOY模板網(wǎng)！
