How do I resolve "cannot import module "greeter" (not found)"

[jason-pezzimenti]

Hi,

I am receiving the following error when I run v run main.v:

cannot import module "greeter" (not found)

#I am following along with the documentation, and I have the following two files:

src/

• main.v
• greeter.v

main.v:

module main
import greeter

fn main() {
	greeter.greet("Jason")
}

greeter.v:

module greeter

fn main() { }
pub fn greet(name string) {
	println(name)
}

Can somebody please help me understand where I'm going wrong? Even if I put the module into a modules folder, and then import it, I still get the same error.

greeter.v should be in a subdirectory named greeter - that's how V defined modules. It doesn't need a fn main unless you plan on running it separately.

You also need a v.mod file at the root of your project, as V used that as an anchor point when looking for local modules. It can be an empty file, or you can create a full one as described in https://docs.vlang.io/package-management.html#publish-package

In other words, set things up like this for them to work:

.
├── src
│   ├── greeter
│   │   └── greeter.v
│   └── main.v
└── v.mod

main.v

module main

import greeter

fn main() {
        greeter.greet('Jason')
}

greeter.v

module greeter

pub fn greet(name string) {
        println(name)
}

output is as expected

$ v run .
Jason
$

Last tip... the src subdir isn't required... some like to use it, some don't. The code works exactly the same if you have

.
├── greeter
│   └── greeter.v
├── main.v
└── v.mod

$ v run .
Jason
$

Thanks.
