it will work well.

Answer 3

paste and paste.deploy are 2 separate modules. You have to install both of them.

To install paste.deploy:

pip install pastedeploy

If it installed correctly, you should be able to run the following in the python interpreter to confirm it's available for use:

>>> import paste
>>> import paste.deploy
>>> paste.deploy.__path__
['/Users/joeyoung/.virtualenvs/reversemapping/lib/python2.7/site-packages/paste/deploy']

Packages support one more special attribute, ____path____. This is initialized to be a list containing the name of the directory holding the package’s ____init____.py before the code in that file is executed.
