ImportError: No module named pathlib

I tried to install it but seems I do not have this module pathlib. Should this package installer install it, when I do not have it?

$ pip install st-package-reviewer
Collecting st-package-reviewer
  Downloading st_package_reviewer-0.2.2.tar.gz
    Complete output from command python setup.py egg_info:
    Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "c:\users\profes~1\appdata\local\temp\pip-build-exvhzl\st-package-reviewer\setup.py", line 2, in <module>
        from pathlib import Path
    ImportError: No module named pathlib

    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in c:\users\profes~1\appdata\local\temp\pip-build-exvhzl\st-package-reviewer\

I am on Windows 10 with anaconda conda --version -> conda 4.3.18.

Later by following:

https://github.com/nvbn/thefuck/issues/287 OSX: "ImportError: No module named pathlib"

I installed successfully this package. However after trying to run it I got this error:

$ st_package_reviewer
