Issues with using libpython-clj with pyenv installed python version #193

Closed bajrachar closed 9 months ago

bajrachar commented 2 years ago

OS: Arch 5.15.11-arch2-1 Libpython-clj 2.006 pyenv 2.2.3

I get a "Failed to find a valid python library!" when using a python library version set as global using pyenv [which is a different version from the system installed one]. It works fine when global is set to the system installed version.

Digging further into libpython-clj code, I found that it is actually trying to find the libpython.so file and the pyenv installed version only installs a libpython.a file.

It worked for me by forcing pyenv to generate a .so file --> $ env PYTHON_CONFIGURE_OPTS="--enable-shared" pyenv install 3.7.5

That’s great. I can’t tell you how many times this has gotten me. Glad to finally see the proper installation pathway!

FYI: For those on a Mac with pyenv this also works

e.g. 

env PYTHON_CONFIGURE_OPTS="--enable-shared" pyenv install 3.10.2
❯ pyenv root
/Users/blah/.cache/pyenv
(py/initialize! :python-executable "/Users/blah/.cache/pyenv/versions/3.10.2/bin/python"
                :library-path "/Users/blah/.cache/pyenv/versions/3.10.2/lib/libpython3.10.dylib")
