Here's how you could do the installation:
On Windows:
pip install virtualenv
virtualenv <your-env>
<your-env>\Scripts\activate
<your-env>\Scripts\pip.exe install google-api-python-client
On MAC/Linux:
pip install virtualenv
virtualenv <your-env>
source <your-env>/bin/activate
<your-env>/bin/pip install google-api-python-client
This should do!
