Python error in terminal

After upgrading from Ubuntu 20.04 to 22.04 I get this error whenever I open a terminal:

    /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 forVIRTUALENVWRAPPER_PYTHON=/usr/bin/python3 and that PATH isset properly.

This is what is in my ~/.bashrc file:

#Virtualenvwrapper settings:export WORKON_HOME=$HOME/.virtualenvsVIRTUALENVWRAPPER_PYTHON=/usr/bin/python3. /usr/local/bin/virtualenvwrapper.sh

I note there is a space after the dot on the last line. Should that be there?

mike@orac:/usr/bin$ ls -la /usr/bin/python3lrwxrwxrwx 1 root root 10 Aug 18 22:39 /usr/bin/python3 -> python3.10

Edit:

After upgrading to 24.04 this solution no longer works:

root@orac:~# pip3 install -U virtualenvwrappererror: 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.

What is the best option?
