Editing or setting the PYTHONPATH as a global var is os dependent, and is discussed in detail here for Unix or Windows.
Usually this will work well, but in complicated situations this might be inappropriate. For example, if PYTHONPATH is set to /www/python:/opt/py, the search path will begin with ['/www/python', '/opt/py'].

Can a text in Latin be understood by an educated Italian who never had any formal teaching of that language? Modifying Python's Search Path¶ When the Python interpreter executes an import statement, it searches for both Python code and extension modules along a search path. The double import trap¶ This next trap exists in all current versions of Python, including 3.3, and can be summed up in the following general guideline: "Never add a package directory,
As you might expect, you can override this directory with the --install-scripts option; in this case, it makes most sense to supply a relative path, which will be interpreted relative Python Site-packages Path The submodules are added to the package namespace trap¶ Many users will have experienced the issue of trying to use a submodule when only importing the package that it is in: In order to have Python see the modules inside each subdirectory, add a blank file called __init__.py to each subdirectory (with two underscores on each side). For Python implementation developers, it can also arise any time we're working on the compiler components that are responsible for generating the bytecode in the first place - that's the main

Much of it applies to earlier versions as well, but I won't be qualifying any of the explanations with version details before 2.6. Python Can't Import Installed Module
This essay only officially covers Python versions back to Python 2.6. This is almost as easy as customizing the script installation directory --you just have to remember that there are two types of modules to worry about, Python and extension modules, which If both options are given, user base and user site will be printed (always in this order), separated by os.pathsep. this content To be clear, if your module's name is "foo": [burnc7 (2016-06-21 15:28:49) git]# ls -l total 1 drwxr-xr-x 7 root root 118 Jun 21 15:22 foo [burnc7 (2016-06-21 15:28:51) git]# cd
Thus, you can put these options into your Distutils config file (see section Distutils Configuration Files): [install] install-base=$HOME install-purelib=python/lib install-platlib=python/lib.$PLAT install-scripts=python/scripts install-data=python/data or, equivalently, [install] install-base=$HOME/python install-purelib=lib install-platlib=lib.$PLAT install-scripts=scripts install-data=data Note Python Module Path Last updated on Oct 30, 2016.

On Unix (and Mac OS X, which is also Unix-based), it also depends on whether the module distribution being installed is pure Python or contains extensions ("non-pure"): Platform Standard installation location If it is installed as your personal config file (on systems that support them), it will affect only module distributions processed by you. For example, you can build everything in one step, and then install everything in a second step, by invoking the setup script twice: python setup.py build python setup.py install If you have a peek at these guys What is the most efficient & fastest way to speed up the installation of packages with thousands of items?
