Now I see the problem. I'm using ~/.guix-profile/bin/guix. Using
~/.config/guix/current/bin/guix, I'm able to build the chromium
package.

So does this mean that, I should put this path
(~/.config/guix/current/bin) before (~/.guix-profile/bin) in $PATH?
Otherwise it will appear that "guix pull" does not upgrade "guix".

What is the purpose of ~/.guix-profile/bin/guix then? Since it is
symbolic linked to /gnu/store/xxx-guix, it is only updated after "guix
package -u"?

I see. Thanks!
