flake8 module installed but not un /usr/bin

Question

I have installed flake8 successfully:

$ pip install flake8
Downloading/unpacking flake8
  Downloading flake8-2.5.4-py2.py3-none-any.whl
Downloading/unpacking mccabe<0.5,>=0.2.1 (from flake8)
  Downloading mccabe-0.4.0-py2.py3-none-any.whl
Downloading/unpacking pep8!=1.6.0,!=1.6.1,!=1.6.2,>=1.5.7 (from flake8)
  Downloading pep8-1.7.0-py2.py3-none-any.whl (41kB): 41kB downloaded
Downloading/unpacking pyflakes<1.1,>=0.8.1 (from flake8)
  Downloading pyflakes-1.0.0-py2.py3-none-any.whl (152kB): 152kB downloaded
Installing collected packages: flake8, mccabe, pep8, pyflakes
Successfully installed flake8 mccabe pep8 pyflakes
Cleaning up...

$ pip list|grep flake
flake8 (2.5.4)
pyflakes (1.0.0)

But it doesn't appear in any of the directories under /usr (/usr/bin/, /usr/sbin/, /usr/local/...) i.e. "which flake8" doesn't show anything, so I can't use from the console manually to verify a script like in the instructions.

This is not enough information to help you. What operating system are you using? What version of Python, pip, etc.? Where did you get pip from? — Ian Stapleton Cordasco, Apr 21 '16 at 21:15
Sorry, It's Ubuntu. pip 1.5.4 from /usr/lib/python2.7/dist-packages (python 2.7) — hosselausso, Apr 23 '16 at 11:47

You should look in ~/.local/ the pip you have installed (from Ubuntu's repositories) is modified to prevent the user from installing packages globally. You'll need to look for something like ~/.local/bin/flake8 and then you'll want to update your shell config to do something like

export PATH="~/.local/bin:$PATH"

So that it finds the executables you install with pip.

I added that line to my bashrc config file, sourced it and it worked. Thanks! – hosselausso Apr 25 '16 at 08:11
