Install new env on the system (64 bit/32 bit)

User virtualenv and pip to avoid dependency problems.

$ yum install python2.6 python-setuptools python-imaging
$ virtualenv mysite-env
$ source mysite-env/bin/activate
(env)$ pip install django==1.3.1 django-cms south
(env)$ django-admin.py startproject mycmsproject

Starting project may issue error PIL (python image lib) not installed. Installing PIL requires python-devel to compile PIL:

  
  $ sudo yum install python-devel
  (env)$ pip search PIL
  (env)$ pip install PIL
  

Install ext. image libs first:

  sudo yum install libtiff-devel libjpeg-devel libzip-devel freetype-devel \
  lcms2-devel libwebp-devel tcl-devel tk-devel
  pip install Pillow
  

Install third-party app in current project:

(vfoss_env)[td@localhost vfoss_org]$ pip install --install-option="--install-purelib=$(pwd)" easy_thumbnails

Install lib locally from source. If a plugin is developed in other directory, it must be installed as a local app. Go to plugin source directory e.g. cmspluginnews. <code> # put dest-dir on PYTHONPATH otherwise there is error message. (vfossenv)[td@localhost vfossorg]$ export PYTHONPATH=/home/td/workspace/vfossorgpj/vfossorg/ ←- destdir (vfossenv)[td@localhost vfossorg]$ python setup.py install –install-purelib=dest_dir

</code>

Dump libs:

  $ pip freeze>requirements.txt
  $ pip install -r requirements.txt 
  

Uninstall specific version.

pip install MySQL_python==1.2.2
