How to include a python .egg library that is in a subdirectory (relative location)?

egg, python

Solution

An .egg is just a .zip file that acts like a directory from which you can import stuff.

You can use the `PYTHONPATH` variable to add the `.egg` to your path, or append a directory to `sys.path`. Another option is to use a `.pth` file pointing to the eggs.

For more info see A Small Introduction to Python eggs, Python Eggs and All about eggs.

For example, if your `library1.egg` contains a package named `foo`, and you add `library1.egg` to `PYTHONPATH`, you can simply `import foo`

If you can't set `PYTHONPATH`, you can write:

import sys
sys.path.append("library1.egg")
import foo

Problem

How do you import python .egg files that are stored in a relative location to the .py code? For example, ``` My Application/ My Application/library1.egg My Application/libs/library2.egg My Application/test.py ``` How do you import and use library1 and library2 from within test.py, while leaving the .egg libraries in-place?
