Ubuntu版本升级后终端启动报错virtualenvwrapper模块缺失及24.04版本下安装方案选择疑问

最近把Ubuntu从20.04升级到22.04后，每次打开终端都会弹出一堆错误提示，具体内容如下：

/usr/bin/python3: Error while finding module specification for 'virtualenvwrapper.hook_loader' (ModuleNotFoundError: No module named 'virtualenvwrapper')

virtualenvwrapper.sh: There was a problem running the initialization hooks.

If Python could not import the module virtualenvwrapper.hook_loader,
check that virtualenvwrapper has been installed for
VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3 and that PATH is
set properly.

我检查了自己~/.bashrc里的virtualenvwrapper配置，内容是这样的：

#Virtualenvwrapper settings:

export WORKON_HOME=$HOME/.virtualenvs

VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3

. /usr/local/bin/virtualenvwrapper.sh

我还注意到最后一行的点后面有个空格，不确定是不是这个空格引发的问题？另外我也确认了系统里Python3的指向：

mike@orac:/usr/bin$ ls -la /usr/bin/python3

lrwxrwxrwx 1 root root 10 Aug 18 22:39 /usr/bin/python3 -> python3.10

后来我又把系统升级到了24.04，结果之前的解决办法完全不管用了。当我尝试用pip3 install -U virtualenvwrapper重新安装时，直接弹出了"externally-managed-environment"的错误：

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.

这时候我就有点纠结了：virtualenvwrapper到底是Debian官方打包的软件，还是非官方的第三方软件？我到底应该用apt install python3-virtualenvwrapper通过系统包管理器安装，还是用pipx install virtualenvwrapper来安装？

琢磨了一会儿后，我最终选择执行sudo apt install virtualenvwrapper来解决这个问题。
