anaconda-navigator does not launch due to qt problems

I am a new user to archlinux, recently I installed anaconda manually from official website, but the navigator won't launch and returned error message below:

***************************************************
(base) [user@host ~] $ anaconda-navigator
2024-11-07 14:44:49,485 - WARNING linux_scaling.get_scaling_factor_using_dbus:32

I have installed qt5-base and qt6-base through pacman.
Having tried manually set temporary environmental varible QT_QPA_PLATFORM=wayland, anaconda-navigator still returned error message below:

***************************************************
(base) [user@host ~] $ anaconda-navigator

This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, minimal, minimalegl, offscreen, vnc, webgl, xcb.

It seems that navigator itself does not implement wayland as an available graphical session?

Re: anaconda-navigator does not launch due to qt problems

(base) [user@host ~] $ anaconda-navigator 

The problem is likely that conda base replaces system libraries with their own version which breaks things.

disable automatic start of base as described in https://wiki.archlinux.org/title/Conda#Usage then try again.

Only enable base for apps that won't work correctly without it.


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: anaconda-navigator does not launch due to qt problems

Thanks for your help. I managed to directly launch navigator outside of base environment, using ./$anaconda_dir/bin/anaconda-navigator .
