I'm using Conda on macOS, and I'm getting an error while building a Rust package that it can't find the libpython3.7m.dylib library. How can I find this?

After doing some research, on Linux you usually can install it from python-dev on Ubuntu, or by enabling --enabled-shared during Python compilation.

Python's build configuration can be found using distutils.sys_config.

from distutils.sysconfig import get_config_var

print(get_config_var("LIBDIR"))
# /Users/liamz/anaconda3/lib

print(get_config_var("LDLIBRARY"))
# libpython3.7m.dylib

Or as a one-liner:

python3 -c 'from distutils.sysconfig import get_config_var; print(get_config_var("LIBDIR"))'
