覆层无法正常使用 #18891

我还是有些不明白这样做的含义

I tried your approach and it was successful. I really appreciate your help, but I don't quite understand the underlying reason for why it worked. Could you shed some light on that?
(Since I'm Chinese, I used AI to translate this English)

I don't know if you have any experience in python or rust, they share the same idea: a file itself can be expressed as a module.

According to the doc, You can define modules with 2 ways:

1. create a file named spam.nu, then spam.nu itself is a module
2. use module keyword inside a file or repl, if you defined it in a file, it's just a submodule

# spam.nu
# here you can't use `export module spam` because nushell doesn't allow it, so I name it spam2.
export module spam2 {
    export def foo [] {
        "foo"
    }

    export alias bar = echo "bar"

    export-env {
        load-env { BAZ: "baz" }
    }
}

I'm so glad you could answer my question. Thank you!
