unknown function: cli004.sub.greetings

[LukyGuyLucky]

With the most updated build (v up) as of today,below code failed to compile.
Was I just simply missing something?
error message:

E:\Learning\vlangpack\ex\cli004>v crun .
cli004.v:6:6: error: unknown function: cli004.sub.greetings

    5 | fn main(){
    6 |     sub.greetings()
      |         ~~~~~~~~~~~
    7 | }

cli004
|_cli004.v
|_sub__
           |__hey.v

cli004.v:

module main
import sub

fn main(){
	sub.greetings()
}

hey.v

module sub

pub fn greetings(){
	println('greetings from sub')
}

Try adding a v.mod file directly in the cli004 subdir, as a sibling file to cli004.v.

[LukyGuyLucky]

Thanks for the prompt help.
I tried but failed,neither directly adding v.mod file as sibling file to cli004.v or,a fresh try again via v init on cli004 folder.Finally the error message just is same as previous:

E:\Learning\vlangpack\ex\cli004>v init
Initialising ...

    5 | fn main(){

folder tree now:

cli004
|__.git
|__.editorconfig
|__.gitattributes
|__cli004.v
|__v.mod
|_______sub
                 |____hey.v

and the v.mod file content:

Module {
	name: 'cli004'
	description: ''
	version: '0.0.1'
	license: 'Apache'
	dependencies: []
}

On Linux, using latest V:

cli004/
├── cli004.v
├── sub
│   └── hey.v
└── v.mod

then

$ v crun .
greetings from sub
$

So... first, make sure you have the latest version of V installed. Depending on how you installed it, you may be able to just do v up, or you may need to re-install from source.

Sorry forget to mention this is Windows 64bit arch.

Just found that:
with the most updated build as of today,the code still faied to build same as yesterday,
but,
when I go back to the parent folder of project folder cli004,and then v crun cli004 it compiles!That is:

E:\Learning\vlangpack\ex\cli004>v crun .
cli004.v:3:1: builder error: cannot import module "cli004.sub" (not found)
    1 |
    2 | module main
    3 | import sub
      | ~~~~~~~~~~
    4 |
    5 | fn main(){

E:\Learning\vlangpack\ex\cli004>cd..

E:\Learning\vlangpack\ex>v crun cli004
greetings from sub

So there is definitely something wrong with my v package,but I just could not figure out(beside v up,I tried to built from a separate folder from the most updated source yesterday but it doesnot help).

Help would be much appreciated.

[LukyGuyLucky]

Finally I found it:
In the parent folder of the project,there is a v.mod file by mistaken.The project will build successfully when deleting this v.mod;if get it back,the above issue occurs again.

Now the issue fixed.

BTW,may I ask is this the intentional design?

[JalonSolov]

No, that is not intentional. The only way it should have happened is if you did NOT have a v.mod file in the cli004 directory, as it should have stopped looking for one when it found that one.

It is intentional to look in the parent if one isn't found in the current directory.

Thanks for letting me know.
