Error: TSError: ⨯ Unable to compile TypeScript

Hey guys, I am facing the problem:

My Project is built on Angular4 with typescript

Node v6.10.3

npm v3.10.10

Travis-CI has this error:

run ng e2e, log:

[03:34:54] E/launcher - Error: TSError: ⨯ Unable to compile TypeScript
Cannot find type definition file for 'jasmine'. (2688)
Cannot find type definition file for 'node'. (2688)

e2e/app.e2e-spec.ts (13,5): Cannot find name 'expect'. (2304)

The command "ng e2e" exited with 4.

My tsconfig.json

{
  "compileOnSave": false,
  "compilerOptions": {
    "outDir": "./dist/out-tsc",
    "baseUrl": ".",
    "paths": {
      "*": ["./node_modules/*", "*"]
    },
    "sourceMap": true,
    "declaration": false,
    "moduleResolution": "node",
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,

    ],
    "lib": [
      "es2016",
      "dom"
    ]
  }
}

this is my QS

Any idea about the problem?

Mine is not a new project, I am running an angular2 project with "@angular/cli": "1.2.0". I updated my typescript version from 2.0.3 to 2.7.2 and now I am getting similar issues while running ng e2e. I have updated all the @types/* to latest versions, also updated jasmine-core but still have the same issue. Does anyone know any other solution to this?

EDIT:

I fixed it by updating ts-node to 5.0.1. Versions above this were giving errors like the one below while running ng e2e:

Experimental support for decorators i…

Apart from the above change, I also changed few lines in protractor.conf.js

Changed:

beforeLaunch: function () { require('ts-node').register({ project: 'e2e' }); },

beforeLaunch: function () { require('ts-node/register') }

Please note: I only had to do the above changes, I didn’t upgrade @types/* or jasmine-core
