使用xpath调试不通过

王君超 · 发表于 2019-9-27 10:46:41

目前使用python2.7版本，是什么原因，感觉自己写的脚本没问题，但总是报错，脚本改了各种方式，其他正常find_element_by_id啊等都能用。就path用不了。请大家帮忙看下。
脚本：
dingdan = driver.find_element_by_xpath("//div[@id='erpHeaderMenus']/div[2]")
ActionChains(driver).move_to_element(dingdan).perform()

报错如下：
Traceback (most recent call last):
  File "C:\Python27\test1.py", line 22, in <module>
dingdan = driver.find_element_by_xpath("//*[@id='erpHeaderMenus']/div[2]")
