Install non-standard package

Python's standard library is installed with Python. When we need non-standard packages, we have to install them first.

1) use Linux repository (Linux environment)

This is a good starting point for installing Python add-on packages. You can look for possible Python packages in Linux repository (such as searching for matplot in Ubuntu Software Center).

2) use pip. Pip is a package manager that comes with Python that connects to Python repository and looks for packages that may exist in it.

For example, use the following methods to install, uninstall, or upgrade web.py:

$pip install web.py

$pip uninstall web.py

$pip install-upgrade web.py

If your Python is installed in a non-standard path (use $which python to confirm the path of the python executable file), for example, in / home/vamei/util/python/bin, you can use the following method to set the path of the pip installation package:

$pip install--install-option= "--prefix=/home/vamei/util/" web.py

3) compile from source code

If none of the above methods can find the library you want, you may need to compile from the source code. Google is often the best place to start.
