Pacman not working after using pyenv

I get this output when I run pacman with PATH having /bin or /sbin

$ sudo pacman
Could not find platform independent libraries <prefix>
Could not find platform dependent libraries <exec_prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
ImportError: No module named site

This error started happening after I pasted this in my profile and continued happening even after removing this and uninstalling pyenv

export PYENV_ROOT="$HOME/.local/pyenv"
command -v pyenv >/dev/null || export PATH="$PYENV_ROOT/bin:$PATH"
eval "$(pyenv init --path)"

Re: Pacman not working after using pyenv

Everything seems to be fine if I set PATH to /usr/bin

$ PATH="/usr/bin" sudo pacman --version

$ type -a sudo
sudo is /sbin/sudo
sudo is /bin/sudo
sudo is /usr/bin/sudo
sudo is /usr/sbin/sudo

Yes, It seems like it is sudo.

$ sudo ls

Re: Pacman not working after using pyenv

/sbin ,  /bin and /usr/sbin are supposed to  be symlinks , it looks like they are regular folders on your system .

Please post the output of

ls -l /usr/sbin /bin /sbin

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

Re: Pacman not working after using pyenv

I was using Howdy. Removing this line from /etc/pam.d/sudo solved this

auth sufficient pam_python.so /lib/security/howdy/pam.py

But I still want to continue using howdy.

You do not consider it a vulnerability that by adjusting $PATH you control the interpreter that loads /lib/security/howdy/pam.py and therefore can control the result from /lib/security/howdy/pam.py by using a specially crafted executable?

Does that mean because it is in the Arch wiki you do not consider it to be a security issue?

Re: Pacman not working after using pyenv

Note: When using Howdy 3.0.0 BETA and above (howdy-beta-gitAUR), the line should be:

auth sufficient /lib/security/pam_howdy.so

I'd look into that instead…

Re: Pacman not working after using pyenv

Also are you using https://aur.archlinux.org/packages/pam-python-git as https://aur.archlinux.org/packages/pam-python depends on python2?

Re: Pacman not working after using pyenv

Oh, and to defend the wiki: it doesn't say anything about adding that to sudo and your ability to impact the interpreter path before logging in is rather limited.

Re: Pacman not working after using pyenv

If you want to use something that relies on the system python, how about not completely overriding the system python?
