All the scripts in my project are giving me a CS0103 and CS1061 errors!

I was working on my project in unity and everything was fin. I created a new script to start working on something and noticed that it wasn't working. Everything I would type, it would underline it. So, I closed it and see 358 errors in my console, all tagged with the error CS0103 and CS1061. I deleted the script and the errors are still there. I tried reinstalling Visual Studio on my mac two times but it's still not working. Thanks!
