ng e2e fails because it cannot find type definition file for 'jasmine' and 'node'

[khtan]

Had to add a line :
import {} from 'jasmine';
to the file app.e2e-spec.ts.

Have also invoked : npm install at type/node and npm install at type/jasmine'. ( Somehow editor is not displaying the at symbol properly )

However, ng e2e still failed because it could not find type definition file for 'jasmine' and 'node'.

Below is the transcript from the shell:

ng e2e

When I updated ts-node to ~3.3.0 in package.json, ng e2e started working again
