在 appium1.6 中，发现 self.driver.tap() 无法使用，
使用例子：
self.driver.tap([(134.3333333333333,111.5)])

报错：
File "/Library/Python/2.7/site-packages/appium/webdriver/webdriver.py", line 203, in tap
action.perform()
File "/Library/Python/2.7/site-packages/appium/webdriver/common/touch_action.py", line 94, in perform

raise wde
WebDriverException: Message: An unknown server-side error occurred while processing the command. Original error: Unhandled endpoint: /session/321CA492-D9ED-414B-9B2A-A9695B4E2CDA/tap -- http://localhost:8100/ with parameters {
wildcards = (

}

有遇到过类似问题的同学吗？如何解决？
