installation
clone repo
$ git clone https://github.com/phipix01/flaskblog
$ cd flaskblog
install pip, make sure you're using the latest version
$ sudo apt-get install python-pip python-dev build-essential
$ pip install --upgrade pip
install virtualenv. use sudo so pip is able to change the mode of /usr/local/bin/virtualenv to 755. (-v = --verbose)
$ sudo pip install virtualenv -v
create and activate a virtual environment for this project folder
$ virtualenv venv
$ source venv/bin/activate
installing the dependencies won't pollute /usr/lib/python2.7/site-packages now and they will co-exist on a project by project basis
$ pip install flask
$ pip install pymongo
if everything worked you can now run python app.py and visit http://localhost:5000
note: if MONGODB_URI is not found try $ source ~/.bashrc and then $ source venv/bin/activate again.
prerequisites
set up some a MongoDB (i used mongoLab) and add MONGODB_URI to environment variables
