Bower install issue

When adding packages with Bower, I'm getting this error message every time I don't know how to resolve the issue?

I was trying to load font awesome or bower install by doing

bower install --save font-awesome
bower install

usr/local/lib/node_modules/bower/lib/node_modules/configstore/index.js:54
                throw err;
                ^

Error: EACCES: permission denied, open '/Users/brandonpowell/.config/configstore/bower-github.json'
