Python Write Better Python Cleaner Code PEP 8

How do I call flake8 to work on my code?

I'm working on badpep8.py and can't seem to invoke flake8 as Kenneth does in the tutorial video. Installing flake8 via pip shows that flake8 is already available.

Really stumped on this seemingly simple process. Thoughts?

Error:

treehouse:~/workspace$ flake8 badpep8.py                                                 
-bash: flake8: command not found

flake8 is a non-standard module and needs to be installed using pip install flake8.

More info at flake8 QuickStart

EDIT: If you are in an environment where flake8 can not be placed on your PATH, you can run it as a python module:

$ python -m flake8 test.py

Thanks, Chris. Unfortunately, I did install, but flake8 didn't work even after installation.
