yarn add ngx-bootstrap import in app.module, as described in docs. ng serve

The log given by the failure

ERROR in ./node_modules/ngx-sharebuttons/index.js
Module build failed: Error: ENOENT: no such file or directory, open '/Users/karp/Documents/git/bgg/geekui2/node_modules/ngx-sharebuttons/index.js'
 @ ./src/app/app.module.ts 32:0-56
 @ ./src/main.ts
 @ multi webpack-dev-server/client?https://localhost:4200 ./src/main.ts

Note that after installation, while there is an index.ts.d file in ./node_modules/ngx-sharebuttons/, there is no index.js.

Here is a stackblitz that works with 4.0.1, can you reproduce the error there?
