    sudo apt install python3-pip
    已经安装

    root@deepin:/home# pip install py7zr
    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.

    米饭虚拟机：

    试下这个命令：pip3 install py7zr --break-system-packages

    可以，但是最好不要用这个命令，会破坏包关系吧

    新版本的限制，首先创建个虚拟环境，然后启用在对应的虚拟环境装包就行了。这个可以从网上搜搜，网上有对应说明。

    按照命令的提示来做就行了，首先安装 pyvenv 的二进制文件，这里以 python3.12 为例：

    sudo apt install python3.12-venv

    然后创建一个独立的虚拟环境来安装 py7zr ：

    mkdir -p ~/.pyvenv
python3 -m venv ~/.pyvenv
~/.pyvenv/bin/python -m pip install py7zr

    运行：

    ~/.pyvenv/bin/python -m py7zr

    你也可以把 ~/.pyvenv/bin 加入 PATH 环境变量，临时加入可以这样子：

    export PATH="$HOME/.pyvenv/bin:$PATH"

    永久加入的话，可以在 bash 的启动文件（比如，~/.bashrc）的末尾写入以下代码：

    case ":${PATH}:" in
	*:"$HOME/.pyvenv/bin":*)
	;;
	*)  export PATH="$HOME/.pyvenv/bin:$PATH"
	;;
esac
