OSError:[WinError 6]通过Python使用Selenium时出现错误的描述符错误

你能帮我写代码吗？我想解析电话号码，但我需要通过点击激活按钮。但是这个按钮有标签，这对我来说是个问题。我怎样才能修好它

from selenium import webdriver
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.common.action_chains import ActionChains
#from selenium.webdriver.common.touch_actions import TouchActions
#import org.openqa.selenium.interactions.Actions


#TouchActions.tap
def main():
    driver = webdriver.Chrome()
    remote = driver.get("https://www.olx.ua/uk/obyavlenie/68200jk71a-torpedo-pod-airbag-infiniti-g-07-14-infiniti-IDGRpUS.html#d97e6d976d;promoted")
    bt_elem = driver.find_elements_by_id("postNewAdLink")
    #print(bt_elem[0])
    #driver.find_elements_by_class_name("contact-button").click()
    #ActionChains(driver).move_to_element(bt_elem).perform().click()

    #bt_elem.get(0).click()
    #TouchActions.tap(bt_elem)

main()

错误：

Traceback (most recent call last):
  File "C:\Users\radus\AppData\Local\Programs\Python\Python38\lib\subprocess.py", line 945, in __del__
    self._internal_poll(_deadstate=_maxsize)
  File "C:\Users\radus\AppData\Local\Programs\Python\Python38\lib\subprocess.py", line 1344, in _internal_poll
    if _WaitForSingleObject(self._handle, 0) == _WAIT_OBJECT_0:
OSError: [WinError 6] Wrong descriptor

你的代码看起来很好。。。您的环境看起来可疑。如果我冒昧猜测一下（因为是子流程模块在抱怨），可能Selenium在您的路径中找不到chrome.exe。Chrome是否在此异常之前打开？

此错误消息

  File "C:\Users\radus\AppData\Local\Programs\Python\Python38\lib\subprocess.py", line 945, in __del__
    self._internal_poll(_deadstate=_maxsize)
  File "C:\Users\radus\AppData\Local\Programs\Python\Python38\lib\subprocess.py", line 1344, in _internal_poll
    if _WaitForSingleObject(self._handle, 0) == _WAIT_OBJECT_0:
OSError: [WinError 6] Wrong descriptor

…表示

subprocess.Popen（）命令出现错误


根据本期的讨论，即使在通过Python模块调用
self.driver.close（）
时也观察到了这种情况


解决方案
该解决方案已从拉取请求中合并，并可在
Selenium v3.8.1

理想情况下，您需要确保：


硒被提升到当前水平
ChromeDriver已更新到当前级别
Chrome更新至当前Chrome版本80.0级别。（根据）
通过IDE清理项目工作区，并仅使用所需的依赖项重建项目
始终在
tearDown（）{}
方法中调用
driver.quit（）
，以优雅地关闭和销毁Web驱动程序和Web客户端实例

看看这里@Vladimir很高兴能帮助您。如果这个/任何答案对你有帮助，对未来的读者有好处。
This is because there is no stdin defined in the `service.py` file for the `subprocess.Popen()` command. Underwater the subprocess tries to create a handle which also looks for stdin under Windows this gets a bit tricky when using `Bash` or `cx_Freeze`. So, `stdin` was defined as well, and the crash is gone. Optionally you can also use:

FNULL = open(os.devnull, 'r')
subprocess.Popen(.... ,stdin=FNULL)
