gs_pip_install v0.2.4 installs in incorrect location
* gs_pip_install version: 0.2.4
* Python version: 3.6.8
* Operating System: Linux (Ubuntu)

### Description
when running gs_pip_install, it does not install in correct python system site package. The site package in my virtualenv was `/home/matthewwong/.local/share/virtualenvs/airflow-dag-utilities-W9jupXEt/lib/python3.6/site-packages` but it was installed in `/home/matthewwong/.pyenv/versions/3.6.8/lib/python3.6/site-packages`.

I suspect the reason it does this because `gs-pip-install` uses a different python to run `pip install`.
- gs_pip_install uses: `/home/matthewwong/.pyenv/shims/python`
- current venv uses: `/home/matthewwong/.local/share/virtualenvs/airflow-dag-utilities-W9jupXEt/bin/python`

### What I Did
Use version 0.2.3 instead
