Tested as different user on godsavethequeen:

> cat hello.zig 
const std = @import("std");

pub fn main() void {
        std.debug.print("hello, world!\n", .{});
}
> source /dev/shm/zig-0.11.0-0/profile 
> zig version
0.11.0
> zig run hello.zig 
hello, world!

With the TESTING prefix changed from /dev/shm/... to /scratch/local2/..., if fails on theinternet while it seems to work on other systems. Log and exit status okay, but lib is just not installed. Note: For a full rebuild test, /scratch/local/USER/.cache/zig/ should be removed. It shouldn't make a difference, but, of course, there could be a bug and wrong cached output reused.
