我的selenium代码第一次使用opera浏览器时抛出错误
我的selenium代码第一次使用opera浏览器时抛出错误
提问于 2022-09-19 11:27:14
我使用opera version=91.0.4516.16和operadriver版本= 105.0.5195.102。我无法用最简单的代码来运行浏览器，也就是：
from selenium import webdriver
from selenium.webdriver.opera.options import Options
s = Options()
s.binary_location = r'C:\Users\Admin\AppData\Local\Programs\Opera\launcher.exe'
driver = webdriver.Opera( executable_path=r'F:\ffmpeg\bin\operadriver.exe')
driver.get("http://google.com/")我使用了不同的代码组合，但同样的错误会一次又一次地发生。
错误是：
Traceback (most recent call last):
File "r:\Youtube\operatest.py", line 96, in <module>
driver = webdriver.Opera( executable_path=r'F:\ffmpeg\bin\operadriver.exe')
File "R:\avirtual\lib\site-packages\selenium\webdriver\opera\webdriver.py", line 75, in __init__

response = self.execute(Command.NEW_SESSION, parameters)

self.error_handler.check_response(response)

在更改我的代码之后。WHich是：
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
from webdriver_manager.opera import OperaDriverManager
# from selenium.webdriver.opera.options import Options
options = webdriver.ChromeOptions()
options.add_argument('allow-elevated-browser')
options.add_experimental_option('w3c', True)
options.binary_location = r"C:\Users\Admin\AppData\Local\Programs\Opera\launcher.exe"
driver = webdriver.Chrome(executable_path=OperaDriverManager().install(), options=options)
driver.get("https://www.google.com")错误是：

driver = webdriver.Chrome(executable_path=OperaDriverManager().install(), options=options)

(The process started from opera location C:\Users\Admin\AppData\Local\Programs\Opera\launcher.exe is no longer running, so OperaDriver is assuming that Opera has crashed.)

使用selenium==4.2.0，您可以解决问题。
还有一件事，我们不能在最新版本的selenium中使用opera的原因是opera不遵循w3的规则，这就是为什么它被selenium删除
from webdriver_manager.opera import OperaDriverManager
from selenium import webdriver
options = webdriver.ChromeOptions()
opera_profile = r"C:\\Users\\LEGEND\\AppData\\Roaming\\Opera Software\\Opera Stable"
options.add_argument('user-data-dir=' + opera_profile)
options._binary_location = r'C:\\Users\\LEGEND\\AppData\\Local\\Programs\\Opera\\launcher.exe'
options = webdriver.ChromeOptions()
options.add_argument('allow-elevated-browser')
options.add_experimental_option('w3c', True)
driver = webdriver.Opera(executable_path=OperaDriverManager().install(), options=options)
driver.get('https://whatsmyip.com')
driver.quit()我希望它能解决你使用operadriver.exe的问题

如果不推荐使用selenium4作为键executable_path，那么您必须使用Service()类的一个实例以及ChromeDriverManager().install()命令，如下所述。
先决条件确保：
Selenium升级到v4.0.0
pip3 install -U selenium安装了用于Python的Webdriver
pip3 install webdriver-managerSelenium v4兼容代码块
from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from webdriver_manager.chrome import ChromeDriverManager
driver = webdriver.Chrome(service=Service(ChromeDriverManager().install()))
driver.get("https://www.google.com")添加了Chrome的答案，确保更改为opera。
