Error: TSError: ⨯ Unable to compile TypeScript

Question

I am facing the problem:

My Project is built on Angular4 with typescript, e2e testing with protractor & karma.

Travis-ci has this error:

[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 (1,32): Cannot find module './app.po'. (2307)

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/*", "*"]

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

My tsconfig.spec.json:

{
  "compilerOptions": {
    "sourceMap": true,
    "declaration": false,
    "moduleResolution": "node",
    "emitDecoratorMetadata": true,

    ]
  },
  "files": [
    "test.ts"
  ],
  "include": [
    "**/*.spec.ts"
  ]
}

I had met same issue. First I remove ts-node and typescript from package.json. then,

npm install ts-node --save-dev
npm install typescript -g 
npm install typescript --save-dev
