"pip show" crash after upgrading

[wimglenn]

• pip version: 18.0
• Python version: 3.7.0
• OS: macOS

create/activate a new virtualenv (python3 -m venv .venv), install latest version of pip, and then:

$ pip show requests --verbose
There was an error checking the latest version of pip
Traceback (most recent call last):
  File "/tmp/.venv/lib/python3.7/site-packages/pip/_internal/utils/outdated.py", line 106, in pip_version_check
    find_links=options.find_links,
AttributeError: 'Values' object has no attribute 'find_links'

Thanks for filing this issue @wimglenn! ^>^

This is a duplicate of #5433.

Ok! I also get this with pip show --verbose --no-cache-dir requests, in case that can help with debugging:

Traceback (most recent call last):
  File "/tmp/.venv/lib/python3.7/site-packages/pip/_internal/utils/outdated.py", line 90, in pip_version_check
    state = SelfCheckState(cache_dir=options.cache_dir)
  File "/tmp/.venv/lib/python3.7/site-packages/pip/_internal/utils/outdated.py", line 25, in __init__
    self.statefile_path = os.path.join(cache_dir, "selfcheck.json")
  File "/usr/local/bin/../Cellar/python/3.7.0/bin/../Frameworks/Python.framework/Versions/3.7/lib/python3.7/posixpath.py", line 80, in join
    a = os.fspath(a)
TypeError: expected str, bytes or os.PathLike object, not bool```
