“无法找到一组匹配的功能”——Selenium with Python 2.7

Question

将 Selenium 3.8.1 与 Python 2.7 与 Firefox Portable 54、64 位一起使用，我在运行此脚本时收到以下错误消息：

from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary

binary_argument = FirefoxBinary(r'C:\Users\[removed]\FirefoxPortable.exe')
driver = webdriver.Firefox(firefox_binary=binary_argument)

driver.get("http://icanhazip.com")

.

Traceback (most recent call last):
  File "F:/cp/python-selenium3/ToyScripts/launch_portable_browser.py", line 5, in <module>
    driver = webdriver.Firefox(firefox_binary=binary_argument)
  File "C:\ProgramData\Anaconda2\envs\automation2\lib\site-packages\selenium\webdriver\firefox\webdriver.py", line 162, in __init__
    keep_alive=True)
  File "C:\ProgramData\Anaconda2\envs\automation2\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 154, in __init__
    self.start_session(desired_capabilities, browser_profile)
  File "C:\ProgramData\Anaconda2\envs\automation2\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 243, in start_session
    response = self.execute(Command.NEW_SESSION, parameters)
  File "C:\ProgramData\Anaconda2\envs\automation2\lib\site-packages\selenium\webdriver\remote\webdriver.py", line 312, in execute
    self.error_handler.check_response(response)
  File "C:\ProgramData\Anaconda2\envs\automation2\lib\site-packages\selenium\webdriver\remote\errorhandler.py", line 242, in check_response
    raise exception_class(message, screen, stacktrace)
selenium.common.exceptions.SessionNotCreatedException: Message: Unable to find a matching set of capabilities

我确实在它消失之前看到了闪屏。另外值得注意的是，手动使用时浏览器工作正常。

我怀疑便携式浏览器需要切换一些设置以允许 Selenium 接管，但这就是我所知道/怀疑的程度。

感谢您对此的任何帮助。

通过修改 DesiredCapabilities 解决：

from selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

binary_argument = FirefoxBinary(r'C:\Users\[removed]\FirefoxPortable.exe')

capabilities_argument = DesiredCapabilities().FIREFOX
capabilities_argument["marionette"] = False

driver = webdriver.Firefox(firefox_binary=binary_argument, capabilities=capabilities_argument)

driver.get("http://icanhazip.com")
