WebDriverException: Message: 'IEDriverServer.exe' executable needs to be in PATH.

詳細描述：想用ie瀏覽器來執行測試用例，按照官方文檔http://code.google.com/p/selenium/wiki/IEDriver 的步驟操作后還是報WebDriverException: Message: 'IEDriverServer.exe' executable needs to be in PATH的錯，配了系統環境變量重啟后也沒用。

 

用下面這種方法設環境變量就可以：

import os
from selenium import webdriver
iedriver = "F:\My\Software\IEDriverServer_x64_3.141.0\IEDriverServer.exe"
os.environ["webdriver.ie.driver"] = iedriver
driver =  webdriver.Ie(iedriver)

#driver = webdriver.Ie()
driver.get('https://www.baidu.com/')
