Question

我是python和kivy的新手，我想运行我的第一个kivy程序。当我运行程序时，我收到此错误：

/usr/bin/python3.4 /home/mmu/PycharmProjects/ShipControl/gui/gui.py

我已经使用

安装了kivy

sudo apt-get install python3-kivy

我错过了什么吗？当我搜索这些错误时，我发现有人建议安装pygame，但这似乎是一个死的项目？

Answer 1

这个问题也发生在16.04对我来说。

我的解决方案，删除ubuntu软件包（在保存方面）并使用pip安装：

sudo apt-get remove python3-kivy
sudo pip3 install kivy

Answer 2

正如inclement在他的评论中所说，切换到kivy-daily解决了这个问题！我不得不在我的机器上进行dist-upgrade来解决一些依赖关系。

Answer 3

我的解决方案与Sebastian相似，但适用于Python 2.7。

sudo apt-get remove python-kivy
sudo pip install kivy
sudo pip install pygame

Answer 4

我刚从git安装了kivy，这是我的bash_history

sudo apt-get install git
mkdir ~/code
cd ~/code
git clone http://github.com/kivy/kivy
cd kivy/
wget http://bootstrap.pypa.io/get-pip.py
python get-pip.py --user
export PATH=$PATH:~/.local/bin/
pip install cython --user
sudo apt-get install python-dev
sudo apt-get install libgles2-mesa-dev
pip install cython --user
sudo apt-get install libgles1-mesa-dev
sudo apt-get install libsdl2-dev     libsdl2-image-dev     libsdl2-mixer-dev     libsdl2-ttf-dev     libportmidi-dev     libswscale-dev     libavformat-dev     libavcodec-dev     zlib1g-dev
make
export PYTHONPATH=~/code/kivy/
pip install pygments --user
pip install docutils --user
python examples/demo/showcase/main.py

使用python3只需将make替换为python3 build_ext --inplace pip with pip3，然后就可以使用python3

运行

判断

sdl2 dependency的安装帮助我： sudo apt-get install python3-sdl2

无法在Ubuntu Wily上运行Kivy
