You guys are amazing! I did two things to get the module to work. I changed the name of the Module to CoinMarketCap instead of Coinmarketcap and also i added a comma at the end of } the wrapper. New to all this raspberry pi and coding so i wanted to say thanks to all of you people!

Hey folks i just made myself a magic mirror with rasp pi3 b+ and although it runs i am having a few problems.

1. Clock seems to stutter when passing the seconds. It works fine for a few seconds. then freezes and then jumps ahead to the right second again
2. I am trying to install the MMM-coinmarketcap module into the magic mirror. I copied all the files to /magicmirror/modules and then ran npm of it. Then i added some code to the config/config.js files. The funny thing is magic mirror will boot up without config error but the mmm-marketcoincap module is nowhere to be seen.
3. Would the clock problem have anything to do with the fact that i keep getting undervoltage warning?? Even though i tried many diff cables and power plugs i keep getting undervoltage warning. The rasp pi itself boots up and works without a problem though.

Thanks for any help!!!
