Could not find a declaration file

[guopuu]

run npm install ...

import Tree from '@naisutech/react-tree'

then error :

Could not find a declaration file for module '@naisutech/react-tree'. 'd:/myWork/my_tcb_client/TCBWebClient/node_modules/@naisutech/react-tree/build/Tree.js' implicitly has an 'any' type.
Try npm install @types/naisutech__react-tree if it exists or add a new declaration (.d.ts) file containing declare module '@naisutech/react-tree';ts(7016)
