Dear meteostat,

I'm using your API to reteive weather data and this happened.

I was running this locally with a small portion of the original data about 10000/17500000 rows and it's working and as I ran the original file in a server this happened.

I would assume the locaiton of 'cache' can't be foudn when executing self.clear_cache
not sure what to do but any help would be great!

this also breaks on aws lambda for the same reason. might suggest you make the cache dir configurable
