I'll just add what I've been using to make this work seamlessly in various projects.

It uses GNU Make, by providing a venv target one can use as a dependency to other targets to ensure a properly created virtual environment.

The venv target itself depends on a, albeit configurable, requirements.txt; the standard python requirements file.

A target test is include as an example of how one would use this.

The trick is to create a symlink to the installed system package. ln -s ${DIST_PACKAGES}/gi ${VENV_NAME}/lib/python${PYTHON_VER}/site-packages/gi, where $DIST_PACKAGE is the location of the python installed libraries on your system.

For those not familiar with make. Create a file named Makefile in the root of your project, copy the contents bellow, and issue the command make configure && make venv.

Makefile

# directory to store virtual environment
VENV_NAME=venv

# python runtime version
PYTHON_VER=3.6

# python executble
PYTHON=${VENV_NAME}/bin/python${PYTHON_VER}

# python local libraries location
DIST_PACKAGES=/usr/lib/python3/dist-packages

# pip requirements file
REQUIREMENTS=requirements.txt

configure:      ## Install required debian packages.
    sudo apt-get -y install python${PYTHON_VER} python3-pip libgirepository1.0-dev
    python3 -m pip install virtualenv pygobject
    make venv

venv:           ## Recreates the virtual environment if needed.
venv: $(VENV_NAME)/bin/activate
$(VENV_NAME)/bin/activate: ${REQUIREMENTS}
    test -d $(VENV_NAME) || virtualenv -p python${PYTHON_VER} $(VENV_NAME)
    ${PYTHON} -m pip install -U pip
    ${PYTHON} -m pip install -r ${REQUIREMENTS}
    ln -s ${DIST_PACKAGES}/gi ${VENV_NAME}/lib/python${PYTHON_VER}/site-packages/gi
    touch $@

test:           ## Runs the test suite.
test: venv
    $(PYTHON) -m pytest tests
