  --- BEGIN ISSUE ---
  setup.py install_requires should have `"click>=7"` not `"click>=6"`
  Thank you for all the work on this tool, it's very useful.
  
  Issue:
  As of 4.4.0 pip-tools now depends on version 7.0 of click, not 6.0.
  
  The argument `show_envvar` is now being passed to `click.option()`
  https://github.com/jazzband/pip-tools/compare/4.3.0...4.4.0#diff-c8673e93c598354ab4a9aa8dd090e913R183
  
  That argument was added in click 7.0
  https://click.palletsprojects.com/en/7.x/api/#click.Option
  compared to 
  https://click.palletsprojects.com/en/6.x/api/#click.Option
  
  Fix: setup.py install_requires should have `"click>=7"` not `"click>=6"`
