Aragon Installation Problems

Iā€™m trying to make an Aragon app and I keep running into errors. Whenever I try to install aragon with the command npm create-aragon-app appname, I get a failed to download app dependencies error. Whenever I run npm start, I get an exceeded call stack error. Does anyone know how to fix this?

Thanks!
