我在src目录下有main.rs和bear.rs.每次编译时,编译器都指向E0658.我已经阅读了E0658的文档,它告诉我这是一个不稳定的功能.

main.rs

mod bear;

use bear::factory::make_bear;

fn main() {
    println!("Hello, world!");
    let bear = make_bear();
}

bear.rs

pub mod factory {
    pub fn make_bear() -> Bear {
        // code to instantiate Bear struct.
    }    
}

当我编译这段代码时,我从编译器得到这个:

error[E0658]: imports can only refer to extern crate names passed with `--extern` on stable channel (see issue #53130)
