Pylint checkers are not working (basestring is not defined) #9

Open robertkossendey opened 3 years ago

robertkossendey commented 3 years ago

pylint 2.7.2 astroid 2.5.1 Python 3.9.2 (default, Feb 24 2021, 13:26:01)

When running pylint with those checkers enabled and with a file that has a unnecessary split statement, I encounter this error. It seems that the pylint_utils is currently bugged.

Stacktrace:

export PYTHONPATH="$PWD/pylint/palantir-pyspark" && pylint src/ --load-plugins=palantir_module

Basestring is no longer available in Python 3. From What’s New In Python 3.0:

The builtin basestring abstract type was removed. They should change basestring for str in pylint_utils file.
