Use venv to resolve error: externally-managed-environment

[liyipeng3]

This patch try to resolve externally-managed-environment error by using separate venv.

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.

感谢贡献。我把commit message改了下。

粗略看了下原因，应该是ubuntu的base镜像进行了更新，引入了https://peps.python.org/pep-0668/ 这个为了解决OS软件包和python冲突的机制。

通过venv解决是合理的。
