我知道错误了

to_capabilities()缺少一个必需的位置参数：'self'

Answer 1

使用选项()从

from selenium.webdriver.firefox.options import Options
options = Options()

而不是来自

options = webdriver.FirefoxOptions

或

它应该是

options = webdriver.FirefoxOptions()

两种方法都很好

Answer 2

我在firefox选项中使用以下代码：

from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.common.by import By
from selenium.webdriver.support import expected_conditions as EC

driver_path = "D:\geckodriver.exe"
options = webdriver.FirefoxOptions()
options.add_argument("--disable-infobars")
options.add_argument("start-maximized")
options.add_argument("--disable-extensions")
options.add_argument("--headless")

driver = webdriver.Firefox(options = options, executable_path= driver_path)
driver.implicitly_wait(30)
driver.maximize_window()
driver.get('http://amazon.de')
print(driver.title)

输出:
