board promicro is unknown/ error compiling

Development Boards Arduino

so I bought a pro micro because of how small it is. I think it’s cool. I had a few bumps trying to get it to work, but eventually everything was going swimmingly. I’m running the latest version of the Arduino IDE. So everything’s working just fine, I’m getting my whole project finished up, and then, I burn up the circuit I had made. I took this as an opportunity to redesign it a little, so after everything was done, I had to go back and change which inputs were witch. Thing is, now it won’t compile. and it’s not the sketch, I tried a blank one and it still won’t compile. I tried it on my Uno and it compiles fine. So, I did more digging and realized that it won’t compile a sketch on any of the sparkfun AVR boards. I haven’t found anywhere on the entire internet where someone is having the same problem. Am I crazy ? What am I not seeing ? Here’s the error I get :

Error compiling.

Looks like the sparkfun boards file got corrputed. Try to reinstall using the board manager.

Thanks, I am using the board manager and the latest version of the ide. But since you mentioned I opened the board manager and removed->reinstalled the sparkfun boards file. Still no luck.

Ok, I have done some research and it looks like its an issue with the IDE for versions newer than 1.6.5. I would bet that you recently updated the IDE with the Sparkfun files already installed. So you will need to download v1.6.5r5 and install it.

Thanks man ! that did the trick ! Those little things like that are reallt annoying, especially when you can’t get info on it. If I can ask, where did you find out about the ide issue ?
