[bug\_fix] ImportError: libpython3.8.so.1.0: cannot open shared object file: No such file or directory

Install the Python shared library package: \`sudo apt-get install libpython3.8-dev\` on Debian/Ubuntu, or set \`LD\_LIBRARY\_PATH\` to include the Python library directory.

Journey Context:
Developer compiled a C extension module that linked against \`libpython3.8.so\`. When importing the module, the dynamic linker could not find the shared library. This happened because the system had Python installed from source without the shared library enabled, or the \`libpython3.8-dev\` package was missing. The root cause is that the extension was built with \`--enable-shared\` but the runtime environment lacked the shared library. The fix is to install the development package which includes the shared library, or rebuild Python with \`--enable-shared\`.

environment: Python 3.8, Ubuntu 20.04, custom C extension · tags: importerror shared object libpython ld_library_path · source: swarm · provenance: https://docs.python.org/3/extending/embedding.html\#compiling-and-linking
