Python working Environment

Setup python working environment with virtual environment and virtual-wrapper (LINUX)

Start the set-up with some testing.

Check whether python-pip is installed using the command

pip version

If pip is not there using this command you can install it using below command

sudo apt-get install python-pip python dev build-essential

This will install pip which will be required to install other pip packages and python-dev setup other header-files.
Now install virtualenvs and virtual wrapper

sudo apt-get install virtualenv && virtualenvwrapper

Now you had installed virtual environment and virtualenvwrapper. now it time to make some alias and setup project working directories.
Create a folder name virtualenvs anywhere your machine. I prefer to create on my home directory.
Use this command to create directory

mkdir ~/virtualenvs

Now its time to make some alias so that handling of the environment will be easier.
open up your bashrc file. Mainly this is located at your home directory in Ubuntu.

vim ~/.bashrc

Copy and paste these lines at the very end of your bashrc file

export PROJECT_HOME=~/virtualenvs

. /usr/local/bin/virtualenvwrapper.sh

These two lines will do all things, but I need some additional features like color for git and root color show git branch name and many more.

parse_git_branch() {

   git branch 2 > /dev/null | sed -e '/^[^*]/d' -e 's/*\(.*\)/(/1)/'

}



ps1= '$(debian_chroot:+($debin)chroot)}\[\033[01:32m\]\u@\h\[\033[00m\]:\[\033[01:34m\]\w\[\033[01:31\]\w\[\033[01:31\]$(parse_git_branch)\[\033[00m\]\$'

unset color_prompt force_color_prompt

Now the environment is ready to use.
To create an environment with this command.

mkproject projectname

To start and existing project

workon project_name
