UnhandledPromiseRejectionWarning

from https://github.com/ubleipzig/dacap/issues/1:

Just a note. Installation went fine.

$ sudo npm install -g @ubleipzig/dacap One the first run, I get a deprecation warning (since ~/data/api-cache wasn't there):

tir@sol:~ $ dacap (node:2392) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: ENOENT: no such file or directory, open '/home/tir/data/api-cache' (node:2392) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.
