Web Browser Automation Help

Hello,
I want to create a constantly running script that will navigate to a website, enter in log in information, then click a button. Basically, I need something that will automatically log me in to my Facebook account, search for all posts with the #Meme on it, and like them, and do this about every hour or so. I also need to be able to upload this to my Raspberry Pi so it will run 24/7. Does anyone know of anything I could possibly use? I've tried Selenium but there was so many errors installing it that I gave up.
