/usr/bin/ld: cannot find -lpython3.6m

I am trying to install bitarray using pip which fails during linking libpython.

  Downloading https://repo/api/pypi/python/packages/packages/eb/fd/bf67cfea810305148ab8a1e8fbdcc5179f56979c73907fec9a36ebd4a58a/bitarray-1.2.0.tar.gz (48kB)

But I could see the Libpython.so files 

/opt/rp/python-3.6.9/lib/libpython3.6m.so.1.0
/opt/rp/python-3.6.9/lib/libpython3.6m.so
/opt/rp/python-3.6.9/lib/python3.6/config-3.6m-x86_64-linux-gnu/libpython3.6m.a

And my $LD_LIBRARY_PATH is /opt/rp/python-3.6.9/lib:/opt/rp/mysql/lib:/opt/rp/python-3.6.9/lib:/opt/rp/mysql/lib.

I tried with all approach that I got but nothing solved the issue.

Solved: Soft linked the libpython3.6m.so to one of the default LD_LIBRARY_PATH.

I think you need to include the directory with libpython3.6m.so in LIBRARY_PATH as well as LD_LIBRARY_PATH. The former is searched at link time. The latter at run time.
