Installation
============

Spyder is quite easy to install on Windows, Linux and MacOS X. Just the read the
following instructions with care.

Installing on Windows Vista/7/8/10
----------------------------------

The easy way
~~~~~~~~~~~~

Spyder is already included in these *Python Scientific Distributions*:

#. `Anaconda <http://continuum.io/downloads.html>`_
#. `WinPython <https://winpython.github.io/>`_
#. `Python(x,y) <https://code.google.com/p/pythonxy>`_

You can start using it immediately after installing one of them (you only need
to install one!).


The hard way
~~~~~~~~~~~~

If you want to install Spyder directly, you need to follow these steps:

#. Install the essential requirements:

   * `The Python programming language <http://www.python.org/>`_
   * `PyQt5 <http://www.riverbankcomputing.co.uk/software/pyqt/download5>`_ (recommended)
     or `PyQt4 <http://www.riverbankcomputing.co.uk/software/pyqt/download>`_

#. Install Spyder and its dependencies by running this command::

       pip install spyder


Updating Spyder
~~~~~~~~~~~~~~~

You can update Spyder by:

* Updating Anaconda, WinPython or Python(x,y).

* Or using this command (in case you *don't* use any of those scientific
  distributions)::

        pip install --upgrade spyder

  .. note::

     This command will also update all Spyder dependencies

|

Installing on MacOS X
----------------------

The easy way
~~~~~~~~~~~~

Thanks to the Spyder team and `Continuum <http://www.continuum.io/>`_, you have
two alternatives:

#. Use the `Anaconda <http://continuum.io/downloads.html>`_ Python distribution.

#. Use our DMG installers, which can be found
   `here <https://github.com/spyder-ide/spyder/releases>`_.

  .. note::
     
     The minimal version to run our DMG's is Mavericks (10.9) since
     Spyder 2.3.5. Previous versions work on Lion (10.7) or higher.


The hard way
~~~~~~~~~~~~

Thanks to the *MacPorts* project, Spyder can be installed using its ``port`` package manager.
There are `several versions`__ available from which you can choose from.

__ http://www.macports.org/ports.php?by=name&substr=spyder

  .. warning::

     It is known that the MacPorts version of Spyder is raising this error:
     ``ValueError: unknown locale: UTF-8``, which doesn't let it start correctly.
   
     To fix it you will have to set these environment variables in your
     ``~/.profile`` (or ``~/.bashrc``) manually::
        
        export LANG=en_US.UTF-8
        export LC_ALL=en_US.UTF-8

|

Installing on Linux
-------------------

Please refer to the `Requirements`_ section to see what other packages you
might need.

#. **Ubuntu**:

   * Using the official package manager: ``sudo apt-get install spyder``.

     .. note::

        This package could be slightly outdated. If you find that is the case,
        please use the Debian package mentioned below.

   * Using the `pip <https://pypi.python.org/pypi/pip/>`_ package manager:

     * Installing: ``sudo pip install spyder``
     * Updating: ``sudo pip install -U spyder``

#. **Debian Unstable**:
  
   Using the package manager: ``sudo apt-get install spyder``

   The Spyder's official Debian package is available `here`__ 
  
   __ http://packages.debian.org/fr/sid/spyder.


#. **Other Distributions**

   Spyder is also available in other GNU/Linux distributions, like

   * `Archlinux <https://aur.archlinux.org/packages/?K=spyder>`_

   * `Fedora <https://admin.fedoraproject.org/pkgdb/acls/name/spyder?_csrf_token=ab2ac812ed6df3abdf42981038a56d3d87b34128>`_

   * `Gentoo <http://packages.gentoo.org/package/dev-python/spyder>`_

   * `openSUSE <https://build.opensuse.org/package/show?package=python-spyder&project=home%3Aocefpaf>`_

   * `Mageia <http://mageia.madb.org/package/show/name/spyder>`_

   Please refer to your distribution's documentation to learn how to install it
   there.

You can execute Spyder without installing it first by following these steps:

#. Unzip the source package
#. Change current directory to the unzipped directory
#. Run Spyder with the command ``python bootstrap.py``
#. (*Optional*) Build the documentation with ``python setup.py build_doc``.

This is especially useful for beta-testing, troubleshooting and development
