【appium】环境配置无误，路径无中文，无空格，提示error: Logcat capture failed: spawn ENOENT

代码如下，提示error: Logcat capture failed: spawn ENOENT

from appium import webdriver
from time import sleep
desired_caps={}
desired_caps['platformName']=   'Android'
desired_caps['platformVersion']=    '5.1.1'
desired_caps['deviceName']= '127.0.0.1:62001'
desired_caps['appPackage']='com.cleanmaster.mguard_cn'
desired_caps['appActivity']='com.keniu.security.main.MainActivity'
driver=webdriver.Remote('http://localhost:4723/wd/hub',desired_caps)

但是将

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

改为

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

运行正常了
不明所以
