Does not work with latest pip

[sk-]

PIP moved the apis to the _internal directory in commit 95bcf8c5f6 , so now the command fails with

Traceback (most recent call last):
  File "/Users/user/.virtualenvs/venv/bin/important", line 7, in <module>
    from important.__main__ import check
  File "/Users/user/.virtualenvs/venv/lib/python3.6/site-packages/important/__main__.py", line 12, in <module>
    from important.parse import parse_dir_imports, parse_file_imports, \
  File "/Users/user/.virtualenvs/venv/lib/python3.6/site-packages/important/parse.py", line 20, in <module>
    from pip.commands.show import search_packages_info
ModuleNotFoundError: No module named 'pip.commands'

I changed the imports to

from pip._internal.commands.show import search_packages_info
from pip._internal.req import parse_requirements as pip_parse_requirements
pip._internal.download.PipSession()

and then it works.

Hi sk- which file did you change?

Hi Sebastian thanks for the response

+1 for this. Using latest Python 3.7, I run into this.

There's another reference to pip.download that breaks also; not sure if it's in the PR.
