Customize Solution for Your Environment

Module / Package Name

Source Directory

# 1. If it is an external package lacking types:
npm install --save-dev @types/@/components/ui

# 2. Or create a declaration file (src/types/declarations.d.ts):
declare module "@/components/ui" {
  const content: any;
  export default content;
}

# 3. If it is a path alias (@/*), update tsconfig.json:
{
  "compilerOptions": {
    "baseUrl": ".",
    "paths": {
      "@/*": ["./src/*"]
    }
  }
}

Root Cause & Mechanism Analysis

Why does this error occur?

TypeScript cannot locate the module in node_modules, path mapping in `tsconfig.json` does not match the file structure, or `@types/<package>` is not installed.
