How to use a Python interpreter in a virtual environment

Question

In Linux Mint distro I have installed pyenv and pyenv-virtualenv so I can activate and deactivate an environment with a given Python version.

I would like to use bpython or ipython interpreters with an environment but I only can install them with sudo install bpython and not with pip into the environment.

For example, if I try to install bpython into environment named gdr with Python 3.8.10 :

(gdr) lab@GdRlab:~/Documents/prPy1$ pip install bpython

The above output does not give much information on how to solve it.

Answer 1

I have always used miniconda (or anaconda), on any operating system. It works very well as an all-in-one solution for managing Python interpreters, libraries, pip installations, and generally everything related to the virtual environment. There are no more operating system-dependent installations.
