首先deepin-v23不让直接在本机安装kivy，害怕你把系统搞坏，因为现在大多数人是不懂linux系统的，都习惯了windows的操作环境，提示让你创建一个虚拟环境去安装，所以这时候要去安装一个虚拟环境，
自带的python没有安装python的虚拟环境管理工具，又要安装一下python的虚拟环境管理工具：
sudo apt install python3-full python3-venv
安装完虚拟环境管理工具，创建虚拟环境(这里我就创建一个名为kivyenv的虚拟环境)：
python -m venv kivyenv
激活虚拟环境：
source kivyenv/bin/activate
安装kivy：
pip install kivy
顺便说一下，deepin-v23自带的python版本是3.12.4。
以下是deepin-v23直接在本机上使用pip安装kivy报错的内容：
–
rkey@rkey-PC:~$ pip install kivy
error: externally-managed-environment
× This environment is externally managed
╰─> To install Python packages system-wide, try apt install
python3-xyz, where xyz is the package you are trying to
install.
If you wish to install a non-Debian-packaged Python package,
create a virtual environment using python3 -m venv path/to/venv.
Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make
sure you have python3-full installed.
If you wish to install a non-Debian packaged Python application,
it may be easiest to use pipx install xyz, which will manage a
virtual environment for you. Make sure you have pipx installed.
See /usr/share/doc/python3.12/README.venv for more information.
note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing –break-system-packages.
hint: See PEP 668 for the detailed specification.

以下是我的deepin-v23自带的python版本信息：
–
(kivyenv) rkey@rkey-PC:~$ python
Python 3.12.4 (main, Jul 9 2024, 09:31:23) [GCC 13.2.0] on linux
Type “help”, “copyright”, “credits” or “license” for more information.
