# 错误[E0583]：未找到模块 `module_name` 的文件

- **ID:** `rust/e0583-file-not-found-for-module`
- **领域:** rust
- **类别:** build_error
- **错误码:** `E0583`
- **验证级别:** ai_generated
- **修复率:** 95%

## 根因

Rust 找不到声明的模块的源文件，可能是因为文件路径错误、文件扩展名错误，或者模块未在 `mod.rs` 或 `lib.rs` 中正确声明。

## 版本兼容性

| 版本 | 状态 | 引入 | 弃用 |
|------|------|------|------|
| rustc 1.68.0 | active | — | — |
| rustc 1.70.0 | active | — | — |
| rustc 1.74.0 | active | — | — |

## 解决方案

1. ```
   Ensure the module file is created with the correct name and path: for `mod module_name;` in `src/lib.rs`, create `src/module_name.rs`.
   ```
2. ```
   If the module has submodules, create a directory `src/module_name/` with a `mod.rs` file inside.
   ```
3. ```
   Check for typos in the `mod` declaration and the file name, ensuring they match exactly (case-sensitive).
   ```

## 无效尝试

- **** — Rust expects module files to follow a specific naming convention based on the `mod` declaration; wrong placement won't be recognized. (50% 失败率)
- **** — Rustc only recognizes `.rs` files for module declarations; other extensions are ignored. (40% 失败率)
