SublimeText linting Python3 with pyflakes in virtualenv

Question

When I open my Python files in Sublime and delete simple things like : at the end of def myFunction():, then I expect the linter to add a red circle in the gutter. But I see nothing in the gutter.

I notice at the bottom of the Sublime window it says "pyflakes(erred)"

Installing the dependencies

# Sublime v 3.1.1
# Sublime package install SublimeLinter
# Sublime package install SublimeLinter-pyflakes

pip3 install pyflakes
which pyflakes
# /Users/macbook/Desktop/my_virtual_env/bin/pyflakes

Trying to tell my linter the path to use in "MyProj.sublime-project" settings

{
    "folders":[
        {
            "path": "."
        }
    ],
    "SublimeLinter.linters.pyflakes.python": "/Users/macbook/Desktop/my_virtual_env/bin/python3"
}

UPDATE: Sublime console output upon loading views.py

SublimeLinter: #10 linter.py:907: 'pyflakes' is linting 'views.py'
SublimeLinter: #10 python_linter.py:42: pyflakes: wanted python is 'None'
SublimeLinter: #10 python_linter.py:93: pyflakes: trying to use globally installed pyflakes
SublimeLinter: #10 python_linter.py:101: WARNING: cannot locate 'pyflakes'. Fill in the 'python' or 'executable' setting.

These settings go under the key settings. E.g.

{
    "folders": [
        {
            "path": "."
        },
    ],

    "settings": {
        "SublimeLinter.linters.pyflakes.python": "..."
    }
}
