From your project's root directory, create a new file .git/hooks/pre-commit

   nano .git/hooks/pre-commit 

Add below code to it. Remember to update VIRTUAL_ENV with path for virtualenv (normally it is $HOME/.virtualenvs/<environ-name>)

   #!/bin/bash
   export VIRTUAL_ENV=~/.virtualenvs/crowd
   if [ -n $VIRTUAL_ENV ]; then
       PATH=$VIRTUAL_ENV/bin:$PATH
   fi
   for f in .git/hooks/pre-commit.d/*; do
       if [ -x "$f" ]; then
           if ! "$f"; then
               echo "COMMIT FAILED!";
               exit 1
           fi
       fi
   done
   unset VIRTUAL_ENV

Now create hook file for flake .git/hooks/pre-commit.d/flake.py

   nano .git/hooks/pre-commit.d/flake.py

Add below code to it

   #!/usr/bin/env python
   import sys
   from flake8.hooks import git_hook, get_git_param
   # `get_git_param` will retrieve configuration from your local git config and
   # then fall back to using the environment variables that the hook has always
   # supported.
   # For example, to set the complexity, you'll need to do:
   #   git config flake8.complexity 10
   COMPLEXITY = get_git_param('FLAKE8_COMPLEXITY', 12)
   STRICT = get_git_param('FLAKE8_STRICT', True)
   IGNORE = get_git_param('FLAKE8_IGNORE', None)
   LAZY = get_git_param('FLAKE8_LAZY', False)
   if __name__ == '__main__':
        sys.exit(git_hook(
            complexity=COMPLEXITY,
            strict=STRICT,
            ignore=IGNORE,
            lazy=LAZY
         ))
