Python Selenium Exception AttributeError：“’Service’对象

Exception AttributeError: "'Service' object has no attribute 'process'" in <bound method Service.__del__ of <selenium.webdriver.ie.service.Service object at 0x0000000002610DD8>> ignored

我的测试套件实现是：

import unittest
from HTMLTestRunner2 import HTMLTestRunner
import os
import Regression_TestCase.RegressionProject_TestCase2


# get the directory path to output report file
#result_dir = os.getcwd()
result_dir = r"E:test_runnersselenium_regression_test_5_1_1ClearCore - Regression TestTestReport"

# get all tests from SearchProductTest and HomePageTest class
search_tests = unittest.TestLoader().loadTestsFromTestCase(Regression_TestCase.RegressionProject_TestCase2.RegressionProject_TestCase2)

# create a test suite combining search_test
re_tests = unittest.TestSuite([search_tests])

# open the report file
outfile = open(result_dir + "TestReport.html","w")

# configure HTMLTestRunner options
runner = HTMLTestRunner.HTMLTestRunner(stream=outfile,title='Test Report',description='Smoke Tests')

# run the suite using HTMLTestRunner
runner.run(re_tests)

任何人都可以帮助为什么这个错误阻止我的测试套件运行？我该如何解决？
