Problem: while running a selenium script, webdriver.py always throwing exception like : File “C:Python27libsite-packagesseleniumwebdriverchromewebdriver.py”, line 67, in __init__ desired_capabilities=desired_capabilities) File “C:Python27libsite-packagesseleniumwebdriverremotewebdriver.py”, line 87, in __init__ self.start_session(desired_capabilities, browser_profile) File “C:Python27libsite-packagesseleniumwebdriverremotewebdriver.py”, line 141, in start_session ‘desiredCapabilities’: desired_capabilities, even if I already used the correct chromedriver location: browser = webdriver.Chrome(“C:/Python27/chromedriver.exe”) the error still showed up.
