之前的用例通过 element_by_name 执行的，都可以跑通，但是在更新了 macaca 之后就不行了，通过 name 和 xpath 定位元素都定位不到。有谁也遇到这样的问题吗？
id 定位是可以的

通过 element_by_name 定位元素
self.driver.element_by_name('我的').click()
得到的报错为：

Traceback (most recent call last):
  File "/Users/test/Desktop/317hu_AppTest/Test_case/demo.py", line 68, in test1_peixun
    self.driver.element_by_name('我的').click()

log 如下

通过 element_by_xpath
elf.driver.element_by_xpath('//*[@text="我的"]').click()

得到的报错结果为

Traceback (most recent call last):

    self.driver.element_by_xpath('//*[@text="我的"]').click()

    raise WebDriverException(error, message, screen, stacktrace)

通 element_by_id 可正常执行
self.driver.element_by_id('id/home_mine_layout').click()
