我正在尝试pip install pyside到我的Raspberry Pi并收到以下错误：

我试过用sudo pip install setuptools --no-use-wheel --upgrade，sudo apt install -y libmysqlclient-dev，python setup.py install和sudo pip install --upgrade setuptools修复它，但没有一个能让我安装Pyside。任何帮助将非常感激。谢谢。

如果重要的话，我正在树莓派3上运行Raspbian Stretch。

Answer 1

你可以试试precompiled wheels的https://www.piwheels.org/

Pi没有pyside二进制轮，所以你需要安装很多prerequisites并从源代码编译：

sudo apt-get install build-essential git cmake libqt4-dev libphonon-dev python2.7-dev libxml2-dev libxslt1-dev qtmobility-dev libqtwebkit-dev

Answer 2

您正在使用哪个python版本，因为此模块仅支持下面列出的版本。

[(2.6), (2.7), (3.2), (3.3), (3.4)]

Answer 3

它看起来很自我解释。

您正在不受支持的python版本上安装该模块。

尝试使用pip2 install pyside安装
