应用程序突然启动和关闭，然后 Pycharm 抛出 element not found 异常

Question

PyCharm 代码：​​

from appium import webdriver



desired_caps = {}

desired_caps['platformName'] = 'Android'

desired_caps['automationName'] = 'UiAutomator2'

desired_caps['platformVersion'] = '10'

desired_caps['deviceName'] = 'AppiumEmulator'

desired_caps['app'] = ('G:\\Appium\\KickStartAppium\\Android_Demo_App.apk')

desired_caps['appPackage'] = 'com.google.android.apps.nexuslauncher'

desired_caps['appActivity'] = 'com.google.android.apps.nexuslauncher.NexusLauncherActivity'

desired_caps['udid'] = 'emulator-5554'





driver = webdriver.Remote('http://127.0.0.1:4723/wd/hub', desired_caps)



driver.implicitly_wait(10)

ClickEle = driver.find_element_by_id("com.code2lead.kwad:id/EnterValue")

ClickEle.click()

PyCharm 错误：

selenium.common.exceptions.NoSuchElementException: Message: An element could not be located on the page using the given search parameters.

Answer 1

好像 Selenium 在这里没有找到你指定的元素：

ClickEle = driver.find_element_by_id("com.code2lead.kwad:id/EnterValue")

selenium 然后总是抛出异常并结束程序。如果您希望代码继续运行，您必须从 selenium 导入 NoSuchElementException 并这样做： 先导入异常：

from selenium.common.exceptions import NoSuchElementException

然后你就可以参考了

except NoSuchElementException:
    # handle the element not existing

我的回答只是从这位绅士的回答（第一个回答）中复制而来：python selenium webscraping "NoSuchElementException" not recognized
