Installation in a Virtual Environment¶
Common dependencies¶
Cython¶
Different versions of Kivy have only been tested up to a certain Cython version. It may or may not work with a later version.
Kivy |
Cython |
---|---|
1.9 |
0.21.2 |
1.9.1 |
0.23.1 |
1.10.0 |
0.25.2 |
1.10.1 |
0.28.2 |
1.11.0 |
0.29.9 |
Dependencies with SDL2¶
Ubuntu example¶
In the following command use “python” and “python-dev” for Python 2, or “python3” and “python3-dev” for Python 3.
# Install necessary system packages
sudo apt-get install -y \
python-pip \
build-essential \
git \
python \
python-dev \
ffmpeg \
libsdl2-dev \
libsdl2-image-dev \
libsdl2-mixer-dev \
libsdl2-ttf-dev \
libportmidi-dev \
libswscale-dev \
libavformat-dev \
libavcodec-dev \
zlib1g-dev
# Install gstreamer for audio, video (optional)
sudo apt-get install -y \
libgstreamer1.0 \
gstreamer1.0-plugins-base \
gstreamer1.0-plugins-good
Note: Depending on your Linux version, you may receive error messages related to the “ffmpeg” package. In this scenario, use “libav-tools ” in place of “ffmpeg ” (above), or use a PPA (as shown below):
- sudo add-apt-repository ppa:mc3man/trusty-media
- sudo apt-get update
- sudo apt-get install ffmpeg
Fedora example¶
You will likely need to do this preliminary step which installs the rpmfusion-free repository unless you have some other 3rd-party repo installed which has the required packages. See rpmfusion.org for complete installation instructions, but only the rpmfusion-free repo is needed for acquiring kivy dependencies (though rpmfusion-nonfree is recommended by rpm fusion installation instructions) as shown in this step.
sudo dnf install -y https://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm
After you ensure that a 3rd-party repository containing any packages that dnf is otherwise unable to find, continue installing dependencies:
# Install necessary system packages sudo dnf install -y python3-devel ffmpeg-libs SDL2-devel SDL2_image-devel SDL2_mixer-devel SDL2_ttf-devel portmidi-devel libavdevice libavc1394-devel zlibrary-devel ccache mesa-libGL mesa-libGL-devel # Install xclip in case you run a kivy app using your computer, and the app requires a CutBuffer provider: sudo dnf install -y xclip # # In case you get the following error preventing kivy install: # annobin: _event.c: Error: plugin built for compiler version (8.0.1) but run with compiler version (8.1.1) # cc1: error: fail to initialize plugin /usr/lib/gcc/86_64-redhat-linux/8/plugin/annobin.so # This has been resolved in later updates after the on-disk release of Fedora 28, so upgrade your packages: # sudo dnf -y upgrade # avoid pip Cython conflict with packaged version: sudo dnf remove python3-Cython sudo pip3 install --upgrade pip setuptools # Use correct Cython version here (Cython==0.29.9 is for 1.11.0): sudo pip3 install Cython==0.29.9
Installation¶
(after installing dependencies above specific to your distribution, do the following remaining steps on any distro where no package is available)
# Make sure Pip, Virtualenv and Setuptools are updated sudo pip install --upgrade pip virtualenv setuptools # Then create a virtualenv named "kivyinstall" by either: # 1. using the default interpreter virtualenv --no-site-packages kivyinstall # or 2. using a specific interpreter # (this will use the interpreter in /usr/bin/python2.7) virtualenv --no-site-packages -p /usr/bin/python2.7 kivyinstall # Enter the virtualenv . kivyinstall/bin/activate # Use correct Cython version here pip install Cython==0.29.9 # Install stable version of Kivy into the virtualenv pip install kivy # For the development version of Kivy, use the following command instead # pip install git+https://github.com/kivy/kivy.git@master

Installation¶
# Make sure Pip, Virtualenv and Setuptools are updated sudo pip install --upgrade pip virtualenv setuptools # Then create a virtualenv named "kivyinstall" by either: # 1. using the default interpreter virtualenv --no-site-packages kivyinstall # or 2. using a specific interpreter # (this will use the interpreter in /usr/bin/python2.7) virtualenv --no-site-packages -p /usr/bin/python2.7 kivyinstall # Enter the virtualenv . kivyinstall/bin/activate pip install numpy pip install Cython==0.29.9 # If you want to install pygame backend instead of sdl2 # you can install pygame using command below and enforce using # export USE_SDL2=0. If kivy's setup can't find sdl2 libs it will # automatically set this value to 0 then try to build using pygame. pip install hg+http://bitbucket.org/pygame/pygame # Install stable version of Kivy into the virtualenv pip install kivy # For the development version of Kivy, use the following command instead pip install git+https://github.com/kivy/kivy.git@master
Install additional Virtualenv packages¶
# Install development version of buildozer into the virtualenv
pip install git+https://github.com/kivy/buildozer.git@master
# Install development version of plyer into the virtualenv
pip install git+https://github.com/kivy/plyer.git@master
# Install a couple of dependencies for KivyCatalog
pip install -U pygments docutils
Start from the Command Line¶
We ship some examples that are ready-to-run. However, these examples are packaged inside the package. This means you must first know where easy_install has installed your current kivy package, and then go to the examples directory:
$ python -c "import pkg_resources; print(pkg_resources.resource_filename('kivy', '../share/kivy-examples'))"
And you should have a path similar to:
/usr/local/lib/python2.6/dist-packages/Kivy-1.0.4_beta-py2.6-linux-x86_64.egg/share/kivy-examples/
Then you can go to the example directory, and run it:
# launch touchtracer
$ cd <path to kivy-examples>
$ cd demo/touchtracer
$ python main.py
# launch pictures
$ cd <path to kivy-examples>
$ cd demo/pictures
$ python main.py
If you are familiar with Unix and symbolic links, you can create a link directly in your home directory for easier access. For example:
Get the example path from the command line above
Paste into your console:
$ ln -s <path to kivy-examples> ~/
Then, you can access to kivy-examples directly in your home directory:
$ cd ~/kivy-examples
If you wish to start your Kivy programs as scripts (by typing ./main.py) or by double-clicking them, you will want to define the correct version of Python by linking to it. Something like:
$ sudo ln -s /usr/bin/python2.7 /usr/bin/kivy
Or, if you are running Kivy inside a virtualenv, link to the Python interpreter for it, like:
$ sudo ln -s /home/your_username/Envs/kivy/bin/python2.7 /usr/bin/kivy
Then, inside each main.py, add a new first line:
#!/usr/bin/kivy
NOTE: Beware of Python files stored with Windows-style line endings (CR-LF). Linux will not ignore the <CR> and will try to use it as part of the file name. This makes confusing error messages. Convert to Unix line endings.
Device permissions¶
When you app starts, Kivy uses Mtdev to scan for available multi-touch devices to use for input. Access to these devices is typically restricted to users or group with the appropriate permissions.
If you do not have access to these devices, Kivy will log an error or warning specifying these devices, normally something like:
Permission denied:'/dev/input/eventX'
In order to use these devices, you can add your user to a group that has the required permissions. For example, in Ubuntu, you can add the user to the ‘input’ group:
$ sudo adduser $USER input
Note that you need to log out then back in again for these permissions to be applied.
