At this point I would not spend any time trying to get the Weather 1.x binding installed and working. Your time would be better spent installing and configuring one of the 2.x weather bindings like OpenWeatherMap or Meteoblue.
But in general, without way more details (as described in How to ask a good question / Help Us Help You) we would never be able to help. What version of OH? How was it installed? What is it running on? Errors in the logs?
