Pouchdb doesn't work?

I am trying to install pouchdb in a typescript (ionic) application. The types don’t work (?)

npm install --save pouchdb
npm install --save-dev @types/pouchdb

When I try to use it (import Pouchdb from ‘pouchdb’), I get this error

ERROR in src/app/services/pouchdb.service.ts(3,8): error TS1192: Module ‘“C:/Users/User/PROG/toto/node_modules/@types/pouchdb/index”’ has no default export.

I tried to add esModuleInterop : true to the tsconfig.app.json file (I’m using IONIC V4). It doesn’t work, I still get the same error when trying import PouchDB from 'Pouchdb' :

ERROR in src/app/services/pouchdb.service.ts(4,9): error TS1192: Module ''pouchdb-find'' has no default export. [ng] src/app/services/pouchdb.service.ts(5,9): error TS1192: Module '"C:/Users/User/PROG/toto/node_modules/@types/pouchdb/index"' has no default export.
[ng] i ｢wdm｣: Failed to compile.

I tried import Pouchdb = require('pouchdb');, result :

ERROR in src/app/services/pouchdb.service.ts(4,1): error TS1202: Import assignment cannot be used when targeting ECMAScript modules. Consider using 'import * as ns from "mod"', 'import {a} from "mod"', 'import d from "mod"', or another module format instead.

I tried import * as PouchDB from 'pouchdb';, result

[ng] Module not found: Error: Can't resolve 'vuvuzela' in 'C:\Users\User\PROG\toto\node_modules\pouchdb\lib'

I also use pouchdb-find, and tried import * as PouchDB_Plugin_Find from 'pouchdb-find';, got

I have no idea what’s going on ?
