安装脚本在执行到这里时报错
error: externally-managed-environment
× This environment is externally managed
╰─> To install Python packages system-wide, try 'pacman -S
python-xyz', where xyz is the package you are trying to
install.
If you wish to install a non-Arch-packaged Python package,
create a virtual environment using 'python -m venv path/to/venv'.
Then use path/to/venv/bin/python and path/to/venv/bin/pip.
If you wish to install a non-Arch packaged Python application,
it may be easiest to use 'pipx install xyz', which will manage a
virtual environment for you. Make sure you have python-pipx
installed via pacman.
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.
[notice] A new release of pip is available: 23.1.2 -> 23.2.1
[notice] To update, run: python -m pip install --upgrade pip
大概意思就是为了防止和系统环境的包起冲突，要么用pacman安装相关包，要么创建一个虚拟环境与系统环境隔绝开。
解决方法：
1.手动下载安装脚本，然后在脚本中找到python -m pip install ***相关语句，改为pacman -S **
2.使用虚拟环境。
