@alexreisner May we know how to fix the timeout error?

Hi @alexreisner, can you guide us on how to solve the timeout error?

[alexreisner]

Yes, sorry for the delay. I think the thing to do here is to add :ip2location_lite to the array on this line, to specify that the lookup doesn't make HTTP requests. (It looks like :maxmind_local should be there too, but I'll handle that separately.)

@alexreisner We have updated https://github.com/ip2location/geocoder/tree/master/lib/geocoder/lookup.rb#L26

Thanks! I'm seeing another error, which I'm looking into. More on that shortly.

For now, two thoughts:

• Please be sure to call super at the beginning of the setup method in the test file.
• When I add the ip2location_ruby gem, I get NoMethodError: private method 'open' called for #<Geocoder::Lookup::Ip2location:0x0... @cache=nil>.

I think the best way to handle the error is to add gem 'ip2location_ruby' at line 10 of the Gemfile.
