import headers show error while running the python files

[HaripriyaB]

When the installation was done as per the instructions in the README.md file the following error occurred:

Traceback (most recent call last):
  File "build_licenses.py", line 6, in <module>
    from .normalize import normalize
ImportError: attempted relative import with no known parent package

Note: The similar issue was occurring for all the python files. Possible cause of this error was the import format :

from .normalize import normalize
from .utils import compressStringToBytes

Due to the dot after the python files name it was showing error.

Version : Python 3.7.7

I had the same issue. A workaround is to not run the .py files directly, but from top directory:

python -m spdx_license_matcher.matcher
