Python Selenium 随机找不到元素

Question

我的脚本对列表中的每辆车都做同样的事情，但在随机段落

vec = WebDriverWait(driver, 60).until(
                        expected_conditions.visibility_of_element_located((
                            'id', 'elp.jobDetailsVehicle.input.jobVehicleEngineCode'))).get_attribute('value')

找不到元素，我收到此错误：

  File "script.py", line 79, in check_recall
    WebDriverWait(driver, 60).until(
  File "C:\Users\Be26.LANGWEDEL\AppData\Local\Programs\Python\Python310\lib\site-packages\selenium\webdriver\support\wait.py", line 89, in until

我已经尝试过诸如 present_of_element_located 之类的presence_of_element_located ——同样的错误。 这是完全随机的。 有任何想法吗？

编辑：这是整个循环：

for line in lines:
    if line[3] == '.':
        license_plate = line[23:33]
        name = line[38:52]
        vin = line[88:105]
        if '-' in license_plate and 'VSSZZZ' in vin:
            driver.switch_to.frame(driver.find_element('id', 'mainFs'))

            entry_license_plate = driver.find_element('id', 'elp.searchVehicle.input.licensePlate')
            entry_license_plate.send_keys(license_plate)

            driver.find_element('id', 'vaws.vehsearch.btn.search').click()

            vec = WebDriverWait(driver, 60).until(
                expected_conditions.visibility_of_element_located((
                    'id', 'elp.jobDetailsVehicle.input.jobVehicleEngineCode'))).get_attribute('value')

            WebDriverWait(driver, 60).until(
                expected_conditions.visibility_of_element_located(('id', 'vaws.sys.recall')))

            try:
                recall = driver.find_element('id', 'recall.info.state').get_attribute('src')
            except NoSuchElementException:
                recall = driver.find_element('id', 'recall.info.warning').get_attribute('src')

            if 'dummy.gif' in recall or 'info.gif' in recall:
                recall = 'Nein'
            elif 'warning.gif' in recall:
                recall = 'Ja'

            final_list += f'{name} | {license_plate} | {vin} | Motor-Kennbuchstabe: {vec} ' \
                          f'| Feldmaßnahme: {recall}\n'

            print('done')

            driver.switch_to.default_content()

            WebDriverWait(driver, 60).until(
                expected_conditions.visibility_of_element_located(('id', 'toolbar.button.new.job'))).click()

该页面是我们公司的内部站点，所以我不允许显示它。

这只是意味着 60 秒超时结束而没有观察到until方法中的内容。

尝试将其放入尝试中：

try:
    vec = WebDriverWait(driver, 60).until(
                        expected_conditions.visibility_of_element_located((
                            'id', 'elp.jobDetailsVehicle.input.jobVehicleEngineCode'))).get_attribute('value')
except:
    print("Timeout")

或者，再试一次，直到我们没有错误：

while True:
    try:
        vec = WebDriverWait(driver, 60).until(
                        expected_conditions.visibility_of_element_located((
                            'id', 'elp.jobDetailsVehicle.input.jobVehicleEngineCode'))).get_attribute('value')
        # break out of the loop if successful
        break
    except:
        # continue the loop if not successful
        continue
    print("Timeout")

好的，我想我发现了问题：一开始我用options.add_argument(f'--user-data-dir={os.getenv("LOCALAPPDATA")}\\Google\\Chrome\\User Data'加载默认配置文件options.add_argument(f'--user-data-dir={os.getenv("LOCALAPPDATA")}\\Google\\Chrome\\User Data'没有这些我没有这些随机错误。有人知道为什么吗？
