any solution?

You can ignore the error by adding "skipLibCheck": true to your compilerOptions in your tsconfig.json file.

"compilerOptions": {
    // ... the remaining options
    "skipLibCheck": true,
}

This will skip type checking of declaration files, which might resolve the TypeScript error you're encountering.
