wal suddenly started asking for sudo

[bootzin]

I feel like after last update wal has suddenly started asking for super user permissions, is that really necessary? As I have an alias to easily change all my system's colors according to a wallpaper and as I also use this alias inside ranger to choose a new wallpaper, it is really annoying having to type my sudo pw everytime. Is that a problem with my system or was it really an intended change? And if so, can I do something so that I don't need to grant it super user permissions again? I mean, it worked just fine before

More specifically, I get the following message when running it without sudo:

Traceback (most recent call last):

pywal version

wal 3.0.0

System

Linux titan 4.16.7-1-ARCH #1 SMP PREEMPT Wed May 2 21:12:36 UTC 2018 x86_64 GNU/Linux

Steps to reproduce

wal -c -g -i ~/Pictures/Wallpapers/current.png -o 'patch-st-colors'

"patch-st-colors" is a script I made that sets defaultbg color to always be "black" (Otherwise I can't use st with transparency) and recompiles st after running wal, as simply running "cat ~/.cache/wal/sequences" didn't always work to change the colorscheme

It shouldn't be asking for sudo at all and I can't reproduce this.

What's the output of ls -l ~/.cache/wal?

Thanks, that solved the error (:
I might have ran wal as sudo once accidentally, so the json file under .cache/wal/schemes had root rw permissions only. As such, I couldn't change it as a normal user
Removing the file as root and running wal again fixed the issue, thanks for the help!
