Defect

Details

It happens during our Docker container build. While it isn't so much of a problem on most distro, it fails the opensuse one:

 /usr/bin/install -c -m 644 airdrop-ng.1 '/output/usr/share/man/man1'
( cd . && python3 setup.py build \
        --build-base /aircrack-ng/scripts/airdrop-ng/build \
        --verbose )
running build
running build_py
running build_scripts
( cd . && /usr/bin/mkdir -p /output/usr/local/lib/python3.6/site-packages/aircrack-ng && \
        python3 ./setup.py install \
                --prefix /output/usr \
                --record /output/usr/local/lib/python3.6/site-packages/aircrack-ng/airdrop-ng-install_files.txt \
                --verbose )
running install
Checking .pth file support in /output/usr/lib/python3.6/site-packages/
/usr/bin/python3 -E -c pass
TEST FAILED: /output/usr/lib/python3.6/site-packages/ does NOT support .pth files
error: bad install directory or PYTHONPATH

You are attempting to install a package to a directory that is not
on PYTHONPATH and which Python does not read ".pth" files from.  The
installation directory you specified (via --install-dir, --prefix, or
the distutils default setting) was:

    /output/usr/lib/python3.6/site-packages/

and your PYTHONPATH environment variable currently contains:

    ''

Here are some of your options for correcting the problem:

* You can choose a different installation directory, i.e., one that is
  on PYTHONPATH or supports .pth files

* You can add the installation directory to the PYTHONPATH environment
  variable.  (It must then also be on PYTHONPATH whenever you run
  Python and want to use the package(s) you are installing.)

* You can set up the installation directory to support ".pth" files by
  using one of the approaches described here:

Please make the appropriate changes for your system and try again.
