Issue importing a library

Sway
1

I created a new internal library by following the sway docs, but I have the issue whenever I try to import it to main.sw and forc build I receive this error
mod internal_lib; | ^^^ Expected an item. 4 | 5 | use internal_lib::Organisation;

This is the library I created:


library;

use std::storage::storage_vec::*;

pub struct Organisation {
    owner: str[40],
    sellers: StorageVec<str[40]>,
}

impl Organisation {
    pub fn new(owner: str) -> Self {
        Self {
            owner,
            
        }
    }
}

Hi there!
Can you add the code where you are importing the lib and the version of the compiler you are working with?
fuelup show

Hi, thanks for the quick response!
the import:
`mod internal_lib;

use internal_lib::Organisation;`

the version:

`Default host: x86_64-unknown-linux-gnu

Hey @timotejGerzelj thanks for the question! Can you please try the following? I was able to build your files fine after these steps. Note I had to resolve a few issues with your internal_lib.sw file.

  1. $ fuelup self update which grabs the latest version of fuelup
  2. $ fuelup default latest which sets the tool chain to the one you just got

This is the toolchain im running
