flake8

flake8 module installed but not un /usr/bin

I have installed flake8 successfully:

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.

Solution

  • 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.
