Installing Git and Virtualenv on Linux or Mac

For Debian/Ubuntu Linux:

sudo apt-get install git python-setuptools

For Redhat/Fedora Linux:

sudo yum install git python-setuptools

For Mac:

Install MacPorts and then:

sudo port install git python-setuptools

Continuing on for all of the above

sudo easy_install pip
sudo pip install virtualenv virtualenvwrapper

Now, you may want to set some defaults in your ~/.bashrc. My relevant entries look like this:

export WORKON_HOME=$HOME/Projects
export VIRTUALENVWRAPPER_HOOK_DIR=$HOME/.virtualenvs
export VIRTUALENVWRAPPER_LOG_DIR=$HOME/.virtualenvs
source /usr/local/bin/virtualenvwrapper.sh

git config --global user.name "Terse Col"
git config --global user.email myemail@gmail.com
git config --global http.sslVerify false

Now away you go:

mkdir $HOME/.virtualenvs
source $HOME/.bashrc
mkvirtualenv mynewproject 
cdvirtualenv

Install Google App Engine on Ubuntu 12.10

Google App Engine  is currently on version 1.7.4 and Ubuntu has recently released Ubuntu 12.10 (Quantal Quetzal). Quantal Quetzal comes with Python 2.7 installed, and App Engine has been providing that version of Python as an option since February 2012. So if you are starting a new App Engine project, it's probably a good time to move to Python 2.7.

I'll explain briefly how you start a new project and there's a nice clean copy of the code at the bottom that you can cut and paste.

Let's get the show on the road. Choose a name for the project and create and switch to a virtual environment:

PROJ=gae_project
mkvirtualenv ${PROJ}
cdvirtualenv

Note that note that "--no-site-packages" and "--distribute" are now the defaults for mkvirtualenv. You don't even need to use "--python=python2.7" on Ubuntu 12.10.

Now we need to know what the latest version of App Engine is, but as of writing it's 1.7.4:

GAE=1.7.4
wget -O /tmp/gae.zip http://googleappengine.googlecode.com/files/google_appengine_${GAE}.zip
unzip /tmp/gae.zip

Now let's create an App Engine app. The app will need a name that has been created in the App Engine Console:

GAE_APP_NAME=dummy
mkdir -p gae_app/static

Now create the app.yaml file:

echo """application: ${GAE_APP_NAME}
version: development
runtime: python27
api_version: 1
threadsafe: true

default_expiration: 7d

handlers:
- url: /static
  static_dir: static
- url: .*
  script: wsgi_app.app
""" > gae_app/app.yaml

And finally the app itself:

echo """import webapp2

class MainPage(webapp2.RequestHandler):
  def get(self):
      self.response.headers['Content-Type'] = 'text/plain'
      self.response.out.write('Please replace me with a decent WSGI App Framework such as Flask')

app = webapp2.WSGIApplication([('/', MainPage)],
                              debug=True)
""" > gae_app/wsgi_app.py

And finally to run the development server:

python ./google_appengine/dev_appserver.py gae_app/

I hope that this has all been of some help to you. Did I miss anything? Please comment below.

Install Google App Engine on Ubuntu 12.04

If you want to use Google App Engine on Ubuntu there are a couple of things to note. Firstly GAE has recently moved to version 1.6.5 and secondly Ubuntu has recently released Ubuntu 12.04 (Precise Pangolin). Precise Pangolin is a Long Term Support (LTS) version of Ubuntu to come with Python 2.7 installed, and App Engine has been providing it as an option since February 2012. So if you are starting a new App Engine project, it's probably a good time to move to Python 2.7.

I'll explain briefly how you start a new project and there's a nice clean copy of the code at the bottom that you can cut and paste.

Let's get the show on the road. Choose a name for the project and create and switch to a virtual environment:

PROJ=py27_gae_project
mkvirtualenv ${PROJ}
cdvirtualenv

Note that note that "--no-site-packages" and "--distribute" are now the defaults for mkvirtualenv. You don't even need to use "--python=python2.7" on Ubuntu 12.04.

Now we need to know what the latest version of App Engine is, but as of writing it's 1.6.5:

GAE=1.6.5
wget -O /tmp/gae.zip http://googleappengine.googlecode.com/files/google_appengine_${GAE}.zip
unzip /tmp/gae.zip

Now let's create an App Engine app. The app will need a name that has been created in the App Engine Console:

GAE_APP_NAME=dummy
mkdir -p gae_app/static

Now create the app.yaml file:

echo """application: ${GAE_APP_NAME}
version: development
runtime: python27
api_version: 1
threadsafe: true

default_expiration: 7d

python ./google_appengine/dev_appserver.py gae_app/

Google App Engine Python2.5 Development in Ubuntu 11.10

How to set up a development environment for Google App Engine, Python2.5 in Ubuntu 11.10.
Firstly, sorry if the code below is badly formatted, but there's a clearer copy of the code at the bottom.

Python2.5 isn't in the Ubuntu 11.10 sources by default so in a console:

sudo add-apt-repository ppa:fkrull/deadsnakes
sudo apt-get update

and install python2.5 and some other stuff:

sudo apt-get install python2.5 python-virtualenv virtualenvwrapper python-pip

Next for project 'oinkyoinker':

export CURRENT=oinkyoinker
mkvirtualenv --no-site-packages --distribute --python python2.5 ${CURRENT}
workon ${CURRENT}
cdvirtualenv
pip install fabric yolk ipython readline

Now download GAE and fix the path:

wget -O /tmp/gae.zip http://googleappengine.googlecode.com/files/google_appengine_1.5.5.zip
unzip /tmp/gae.zip
echo "../../../google_appengine" > lib/python2.5/site-packages/gae.pth

and create a simple file server app:

mkdir -p application/static

echo """application: oinkyoinker
version: 1
runtime: python
api_version: 1
default_expiration: "7d"
handlers:
- url: /
  static_dir: static
""" > application/app.yaml

and run it:

./google_appengine/dev_appserver.py application/

Hope this helped you too.

Install Git, Pip and VirtualEnv and VirtualEnvWrapper on Ubuntu in a Minute

From a terminal, type:

sudo apt-get install git python-setuptools
sudo easy_install pip
sudo pip install virtualenv virtualenvwrapper

Now, you may want to set some defaults in your ~/.bashrc. My relevant entries look like this:

export WORKON_HOME=$HOME/Projects
export VIRTUALENVWRAPPER_HOOK_DIR=$HOME/.virtualenvs
export VIRTUALENVWRAPPER_LOG_DIR=$HOME/.virtualenvs
export VIRTUALENVWRAPPER_VIRTUALENV_ARGS='--no-site-packages --distribute'
source /usr/local/bin/virtualenvwrapper.sh

git config --global user.name "Terse Col"
git config --global user.email myemail@gmail.com
git config --global http.sslVerify false

Now away you go:

mkdir $HOME/.virtualenvs
source $HOME/.bashrc
mkvirtualenv mynewproject 
cdvirtualenv
