Trouble using virtualenv_create

[Jsalas424]

I'm trying to create a virtual environment, but get the following error

> virtualenv_create()
Error: Tools for managing Python virtual environments are not installed.

Install venv with:
$ sudo apt-get install python3-venv

Traceback:
4. stop(message, call. = FALSE)
 
3. virtualenv_module(python)
 
2. module %||% virtualenv_module(python)
 
1. virtualenv_create("r-reticulate")

So I installed python3-venv and tried again, got the same error. I proceeded reboot the system and attempted again, no luck. It looks like I do have it installed:

jon@rstudio:~$ sudo apt install python3-venv

Reticulate Config:

numpy:           [NOT FOUND]

NOTE: Python version was forced by RETICULATE_PYTHON_FALLBACK

How do I change the RETICULATE_PYTHON_FALLBACK?

This is in a Ubuntu Jammy Jellyfish VM dedicated to running RStudio Server.

Resolved by running python3 -m pip install virtualenv from bash.

I had the same problem and could solve it the same way.
However, I think this should not be necessary and it should work also with the deb package.
