ValueError: Namespace GdkPixbuf not available caffeine-ng error

Hi there were some arch updates I recently installed that has broken some stuff on my computer.

I can't get caffeine-ng to work anymore. I get the error ValueError: Namespace GdkPixbuf not available

I did try installing gdk-pixbuf2 via pacman, but this hasn't solved the issue.

I am currently running arch 1.4

(base) [user@user ~]$ caffeine

Re: ValueError: Namespace GdkPixbuf not available caffeine-ng error

GDK Pixbuf will be built against python 3.9 whereas you try to use a 3.8 python. Why are you running caffeine from a user local environment anyway?

I'm not sure what you mean by "local user environment", I am running caffeine in terminal to get it working. I tried running via app finder but it just gives a red stop sign

I have installed caffeine from AUR: https://aur.archlinux.org/packages/caffeine-ng/

Re: ValueError: Namespace GdkPixbuf not available caffeine-ng error

Then  you've installed a package into a home  path.

Check through your .profile and similar shell files remove anything that changes your PATH and/or PYTHONPATH to include miniconda. Restart your shell, verify with

type -a python 
python --version

that you get /usr/bin/python and 3.9.1 respectively and  build and install the package again. conda should have the "conda" command to explicitly set up it's local environment, do that only when actually working on local python  packages.

Re: ValueError: Namespace GdkPixbuf not available caffeine-ng error

Thanks! I edited my .bashrc file:

#
# ~/.bashrc
#

# If not running interactively, don't do anything
#[[ $- != *i* ]] && return

#alias ls='ls --color=auto'
#PS1='[\u@\h \W]\$ '

# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$('/home/user/miniconda3/bin/conda' 'shell.bash' 'hook' 2> /dev/null)"
#if [ $? -eq 0 ]; then
    #eval "$__conda_setup"
#else
    if [ -f "/home/user/miniconda3/etc/profile.d/conda.sh" ]; then
        . "/home/user/miniconda3/etc/profile.d/conda.sh"
    #else
        #export PATH=""$PATH:/home/user/miniconda3/bin"
   # fi
fi
#unset __conda_setup
# <<< conda initialize <<<

and in /etc/profile i've commented out:
#export PATH="$PATH:/usr/local/miniconda/bin"

running type -a python gives me:

[user@user ~]$ type -a python
python is /usr/bin/python
python is /bin/python

I reinstalled caffeine-ng and it's all working great again

thanks
