AttributeError: ‘NoneType’ object has no attribute ‘to_capabilities’

执行test_driver()后，报错：AttributeError: ‘NoneType’ object has no attribute ‘to_capabilities’

def test_driver():
    from appium import webdriver

    appium_server_url = 'http://localhost:4723'
    capabilities = {
        'platformName': 'Android',
        'automationName': 'uiautomator2',
        'deviceName': '127.0.0.1:62001',
        'appPackage': 'com.android.settings',
        'appActivity': '.Settings',

解决办法

添加 options = UiAutomator2Options().load_capabilities(capabilities)：

def test_driver():
    from appium import webdriver
    from appium.options.android import UiAutomator2Options

    appium_server_url = 'http://localhost:4723'
    capabilities = {
        'platformName': 'Android',
        'automationName': 'uiautomator2',
        'deviceName': '127.0.0.1:62001',
        'appPackage': 'com.android.settings',
        'appActivity': '.Settings',
    }
    options = UiAutomator2Options().load_capabilities(capabilities)
    webdriver.Remote(command_executor=appium_server_url, options=options)
