Which version of python are you using?

[suraneti]

@trinayanbhatt Python2 is not compatible with this library.

[trinayanbhatt]

@saguywalker I have tried with python3 both with Python 3.5.2 and with Python 3.7.

[trinayanbhatt]

@suraneti Yes I am trying with python3 only.

According to https://github.com/psf/black/issues/439#issuecomment-514227490, you should try to run pip install --pre black with Python 3.7.
