I\'ve installed flycheck for Emacs Python on Ubuntu 15.04.

Answer 1

As @Jules mentioned:

Flycheck simply calls the pylint executable that should be somewhere in your path.

So it becomes critical that the correct flake8 version is accessible within emacs. Since you are using pipenv, you should be sure to first install flake8 within your project's environment, and then ensure that your environment is activated before launching emacs.

From within your project root directory:

pipenv install flake8
pipenv shell

You can then launch emacs from the commandline, and flycheck will connect with the correct version of flake8 for your project.
