Meet the problem of "SessionNotCreatedException: Unable to find a matching set of capabilities"

in #python • 6 years ago

I am a Mac User, and I meet the problem of "Unable to find a matching set of capabilities" when I want to learn the selenium. I have installed python , Anaconda, pip, selenium.
Then I type the following code :

from selenium import webdriver
driver=webdriver.Firefox()

      Howere, I got the following error messages:

SessionNotCreatedException: Unable to find a matching set of capabilities

   I searched it on the internet and many people  ask people to check the correct version. However, somebody say that ,must make sure that Firefox must in the "Applications" folder , and do not rename "Firefox".  I followed the suggestion and I got it OK now.  In the past , I reinstalled the Firefox because of version update and rename the new version to "Firefox2" , and so this trouble occured.
Now I hope that this article can help someone debug who also meet this kind of trouble.
