Root Cause

The submodule file or directory does not exist, or the module declaration is missing in the parent module.

子模块文件或目录不存在，或父模块中缺少模块声明。

Workarounds

  1. 95% success Create the missing file `src/module/submodule.rs` and add `pub mod submodule;` in `src/module/mod.rs` or `src/module.rs` 
    Create the missing file `src/module/submodule.rs` and add `pub mod submodule;` in `src/module/mod.rs` or `src/module.rs`
  2. 90% success If the module is a directory, ensure it contains a `mod.rs` file that declares the submodule 
    If the module is a directory, ensure it contains a `mod.rs` file that declares the submodule

中文步骤

  1. Create the missing file `src/module/submodule.rs` and add `pub mod submodule;` in `src/module/mod.rs` or `src/module.rs`
  2. If the module is a directory, ensure it contains a `mod.rs` file that declares the submodule

Dead Ends

Common approaches that don't work:

  1. Add `pub mod submodule;` to lib.rs or main.rs even if submodule is in a subdirectory 70% fail

    The declaration must be in the parent module file (e.g., `module/mod.rs` or `module.rs`), not necessarily the crate root.

  2. Use `#[path = "path/to/submodule.rs"]` without creating the actual file 85% fail

    The file must exist on disk; the path attribute only overrides the default lookup path.
