Appium使用python进行自动化测试问题，webdriver.Remote报编码错误 - 51Testing软件测试论坛

#coding: utf-8
import os
from time import sleep
from appium import webdriver
# Returns abs path relative to this file and not cwd
PATH = lambda p: os.path.abspath(
os.path.join(os.path.dirname(__file__), p)
)
desired_caps = {}
desired_caps['platformName'] = 'Android'
desired_caps['browserName'] = ''
desired_caps['platformVersion'] = '4.4.2'
desired_caps['appPackage'] = 'com.njzx.lehuoli'
desired_caps['appActivity'] = '.ui.activity.base.MainActivity'
desired_caps['deviceName'] = 'emulator-5554'
driver = webdriver.Remote('http://127.0.0.1:4723/wd/hub/',desired_caps)
el = find_element_by_accessibility_id('com.njzx.lehuoli:id/button_login')
el.click()
time.sleep(5)
driver.quit()
运行以后报错：
