标签: file-saver

In my Angular-12 project I installed file-saver:

npm install file-saver@2.0.5

npm install --save exceljs

ng generate service services/export-excel

Then in the export-excel service, I added:

import * as fs from 'file-saver';

I got file-saver highlighted

with this error:

Could not find a declaration file for module 'file-saver'. 'c:/xampp/htdocs/myapp/node_modules/file-saver/dist/FileSaver.min.js' implicitly has an 'any' type. Try npm i --save-dev @types/file-saver if it exists or add a new declaration (.d.ts) file containing declare module 'file-saver';

But I didn't use:

@types/file-saver

How do I …
