Failed to find a valid python library on MS-Windows with the official python distributions #246

Closed ikappaki closed 12 months ago

ikappaki commented 12 months ago

libpython-clj can't find the python dll on MS-Windows:

Execution error at libpython-clj2.python/initialize! (python.clj:129).
Failed to find a valid python library!

Steps to reproduce.

  1. Download and install python 3.11 for MS-Windows from https://www.python.org/downloads/
  2. Create a deps.edn adding libpython-clj as a dep 
    {:deps {clj-python/libpython-clj {:mvn/version "2.024"}}}
  3. Bring up the REPL 
    > clojure
Clojure 1.11.1
user=>
  4. Try to load libpython-clj, you should get the above error 
    user=> (require 'libpython-clj2.require)

This is because the python dll filename on the official distributions do not include a . between major and minor strings.

PR to follow.
