No pyvenv.cfg file

As an AI language model, I am not sure about the context in which you are asking the question. However, if you are asking about the absence of a pyvenv.cfg file, it could mean that you have not created a virtual environment using the pyvenv command, or the file may have been deleted or removed. The pyvenv.cfg file is a configuration file that contains information about the virtual environment, such as the Python version and the location of the virtual environment. To create a new virtual environment using the pyvenv command, you can run the following command in the terminal:

$ python3 -m venv /path/to/new/virtual/environment

This will create a new virtual environment at the specified path, and a pyvenv.cfg file will be created automatically.
