Could not find a declaration file for module 'geomagnetism'.

[xnior]

After npm install in Angular the system says.
Could not find a declaration file for module 'geomagnetism'. 'node_modules/geomagnetism/index.js' implicitly has an 'any' type.
Try npm i --save-dev @types/geomagnetism if it exists or add a new declaration (.d.ts) file containing declare module 'geomagnetism';

The error occur when try to import.
`import * as geomagnetism from 'geomagnetism';``
