"Cannot find proj.db" issue #271

Closed Jing23333 closed 2 months ago

Jing23333 commented 2 months ago

Hi!

When I run python fmm_test.py in Cygwin (under windows 10), I got an error of "ERROR 1: PROJ: proj_identify: Cannot find proj.db". I tried to find the file or the path that contains proj.db, but it seems that there is no "proj.db" under the cygwin64 folder. Where I can find this file and add it to the environment_variable? or if there is other method I can solve the issue?

Thank you very much!

The issue has been solved. I installed the proj package in Cygwin and set the PROJ_LIB environment variable using the path of proj.db.

Thank you!
