Thanks @native-api. I think more is going on that what you describe based on this inconsistent behavior with conda, a tool that comes with the anaconda installation via pyenv. See below for a demo of what I am talking about.

Diagnosed the issue. The environment is actually still active in the subshell (all the revelant envvars are set), it just disappears from the prompt because PS1 is reset by /etc/zshrc's code.

In any case, I was writing a fix by detecting this situation (PS1 is reset to the original value), but is stumped by the fact that when pyenv-sh-activate code runs, PS1 appears to the blank (expands to a blank value) -- so I cannot check it.

Do you know anything about that? This seems to be another one of Zsh's quirks. Googling and checking the man pages came up empty so far.

No, I didn't know this, but I do see the message from time to time that they are not going to show the environment name by default in the future, and don't know if it's related to me not seeing it. But as you can see from the terminal output, it's not even about how it's activated, it's that things are different before doing cd .. cd - and not able to be streamlined with cd .. && cd - . Namely, it's this conda activate that seems to not work unless time is spend outside of the directory.

Also, my .zshrc file is very boilerplate, I have oh-my-zsh installed and nothing custom to conda init. As a matter of fact it is interesting, somehow conda init is being run or the environment is being activated in some more robust way when you exit and reenter the directory.

ZSH_THEME="robbyrussell"

# Set list of themes to pick from when loading at random

CommandNotFoundError: Your shell has not been properly configured to use 'conda activate'.

Found the reason for this. Since version 4, Conda doesn't copy itself to alternate environments but rather creates a shell function conda. Which, unlike envvars, does not survive spawning a new shell.

Now, why do you expect a virtual environment to survive spawning a new shell? This doesn't work with base virtualenv, venv or conda, either.
