Qt package from here or a custom build of Qt (preferably Qt 5.12 or greater)
A Python interpreter (version Python 3.5+ or Python 2.7). You can use the one provided by HomeBrew, or you can get python from the official website .
XCode 8.2 (macOS 10.11), 8.3.3 (macOS 10.12), 9 (macOS 10.13), 10.1 (macOS 10.14)
CMake 第 3.1 版或更高版本
Git version 2 or greater
libclang from your system or the prebuilt version from the
Qt 下载page is recommended.
virtualenvis strongly recommended, but optional.
sphinxpackage for the documentation (optional).Depending on your OS, the following dependencies might also be required:
libgl-dev,
python-dev,
python-distutils,and
python-setuptools.
virtualenv
allows you to create a local, user-writeable copy of a python environment into which arbitrary modules can be installed and which can be removed after use:
virtualenv testenv
source testenv/bin/activate
pip install sphinx # optional: documentation
pip install numpy PyOpenGL # optional: for examples
will create and use a new virtual environment, which is indicated by the command prompt changing.
If you don’t have libclang already in your system, you can download from the Qt servers:
wget https://download.qt.io/development_releases/prebuilt/libclang/libclang-release_60-mac-clazy.7z
Extract the files, and leave it on any desired path, and then set these two required environment variables:
7z x libclang-release_60-linux-Rhel7.2-gcc5.3-x86_64-clazy.7z
export CLANG_INSTALL_DIR=$PWD/libclang
可以克隆官方存储库通过：
git clone --recursive https://code.qt.io/pyside/pyside-setup
签出想要构建的版本，如 5.14：
cd pyside-setup && git checkout 5.14
注意
Keep in mind you need to use the same version as your Qt installation
Check your Qt installation path, to specifically use that version of qmake to build PySide2. e.g.
/opt/Qt/5.14.0/gcc_64/bin/qmake
.
Build can take a few minutes, so it is recommended to use more than one CPU core:
python setup.py build --qmake=/opt/Qt/5.14.0/gcc_64/bin/qmake --build-tests --ignore-git --parallel=8
要安装到当前目录，仅仅运行：
python setup.py install --qmake=/opt/Qt/5.14.0/gcc_64/bin/qmake --build-tests --ignore-git --parallel=8
You can execute one of the examples to verify the process is properly working. Remember to properly set the environment variables for Qt and PySide2:
python examples/widgets/widgets/tetrix.py
