Failed to lookup view "categories" in views directory

[ghdms]

eg, I tried "npm i nodebb-theme-classic" and apply this theme,
I got a error "Failed to lookup view "categories" in views directory".
I am using nodebb v3.2.0, anyone knows why this error is reported?

@ghdms ghdms Did you do a ./nodebb build?

That theme isn't updated for 3.x so even after a ./nodebb build it won't work.

[ghdms]

@josef Sure, I did "./nodebb stop && ./nodebb build && ./nodebb start".
@baris If I want to use some theme that isn't updated for 3.x, I should downgrade nodebb 3.x -> 2.x?

[josef]

@ghdms Yes, unless you have the knowledge to adapt the theme to 3.x

@josef I got it, thanks.
