This is a dumping ground for my python2 memory.
PIP
pip is a dependency manager for python. It stores all dependencies in requirements.txt
pip install -r requirements.txt
VirtualEnv
This is special environment for pythons so you don't have to worry about mixing up system wide dependencies.
So virtualEnv 1 has python version 2.7.11 and virtualEnv 2 has python version 2.7.12
To install virtualenv.
pip install virtualenv
to setup an virtual enviroment use the following command.
virtualenv project1
This will create a sub directory called project1.
Then you can activate the virtualenv by using the following command.
source ./project1/bin/activate
Once in the virtual environment you can see which python is setup
which python
or list all dependencies
pip list
You can leave the virtual environment by using the following command.
deactivate.
