selenium - NS_ERROR_SOCKET_ADDRESS_IN_USE

Question

我的代码:

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

driver = webdriver.Firefox()
driver.get("https://www.youtube.com")
login_wait = WebDriverWait(driver, 10)

textbox = login_wait.until(EC.visibility_of_element_located((By.ID, 'search')))
textbox.send_keys("a")

time.sleep(10)
driver.close()

Python 控制台中没有错误，但 geckodriver.log:

Answer 1

如果您查看错误堆栈跟踪，错误说明了一切:

1514074509913   Marionette  ERROR   Error on starting server: [Exception... "Component returned failure code: 0x804b0036 (NS_ERROR_SOCKET_ADDRESS_IN_USE) [nsIServerSocket.initSpecialConnection]"  nsresult: "0x804b0036 (NS_ERROR_SOCKET_ADDRESS_IN_USE)"  location: "JS frame :: chrome://marionette/content/server.js :: MarionetteServer.prototype.start :: line 95"  data: no]

这本质上意味着 Marionette 正在尝试与您建立连接 localhost 即 127.0.0.1 通过端口 49865 但该端口当前由于以下原因之一而被占用:

• Port 49865 当前正被在您的 localhost 之外运行的其他应用程序使用。 。
• Port 49865 由您的 localhost 运行的某些服务使用。
• Port 49865 尚未被 WebDriver 的悬空实例释放。变体例如GeckoDriver , ChromeDriver , IEDriverServer或GhostDriver .

解决方案:

解决方案是以下任一/所有步骤:

• 始终使用 driver.quit() 内 tearDown() 你的方法Automation Script 。如果 WebDriver 的任何悬空实例变体例如GeckoDriver , ChromeDriver , IEDriverServer或GhostDriver存在于您的系统上，请以编程方式/手动杀死它们。
• 确保 Port 49865 不被您的 localhost 运行的任何其他应用程序使用。 。
• 确保 Port 49865 不被从 localhost 运行的某些服务使用。
• 使用CCleaner 执行 Tests 之前和之后的工具从您的系统中清除操作系统的杂务。
• 采取 System Reboot
• 如果问题仍然存在，uninstall <强> Mozilla Firefox Browser 到 Revo Uninstaller 并安装 Mozilla Firefox Browser 的新实例
