Installation and Configuration
==============================
You can either include *Jedi* as a submodule in your text editor plugin (like
jedi-vim_ does it by default), or you can install it systemwide.
System-wide installation via a package manager
----------------------------------------------
You can install *Jedi* directly from pypi using pip::
sudo pip install jedi
If you want to install the current development version::
sudo pip install -e git://github.com/davidhalter/jedi.git#egg=jedi
.. note:: This just installs the Jedi library, not the editor plugins. For
information about how to make it work with your editor, refer to the
corresponding documentation.
Manual installation from a downloaded package
---------------------------------------------
If you prefer not to use an automated package installer, you can download a
copy of *Jedi* and install it manually.
To install it, navigate to the directory containing `setup.py` on your console
and type::
sudo python setup.py install
Inclusion as a submodule
------------------------
If you use an editor plugin like jedi-vim_, you can simply include *Jedi* as a
git submodule of the plugin directory. Vim plugin managers like Vundle_ make it
very easy to keep submodules up to date.
