Install all module to a different machine

Now if you want to install all these modules to some other system, then you can use some python commands, if you are not using any configuration management tools like chef.

Then by using any of the command get the list, add then to a file and add pip install to each line and create a complete shell file like this.

pip install     visitor                 ;
pip install     webencodings            ;
pip install     Werkzeug                ;
pip install     wtf                     ;
pip install     WTForm                  ;
pip install     WTForms                 ;

Now just login to machine and run this file.

>> installtion.sh

All your module will be installed now to this machine.
