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'.

My tsconfig.json:

{   "compileOnSave": false,   "compilerOptions": {     "outDir": "./dist/out-tsc",     "baseUrl": ".",     "paths": {       "*": ["./node_modules/*", "*"]     },     "sourceMap": true,     "declaration": false,     "moduleResolution": "node",     "emitDecoratorMetadata": true,     "experimentalDecorators": true,     "target": "es5",     "types": [ "node", "jasmine" ],     "typeRoots": [       "./node_modules/@types"     ],     "lib": [       "es2016",       "dom"     ]   } } 

My tsconfig.spec.json:

{   "compilerOptions": {     "sourceMap": true,     "declaration": false,     "moduleResolution": "node",     "emitDecoratorMetadata": true,     "experimentalDecorators": true,     "lib": [       "es2016",       "dom"     ],     "outDir": "../out-tsc/spec",     "module": "commonjs",     "target": "es5",     "baseUrl": "",     "types": [       "jasmine",       "node"     ],     "typeRoots": [       "../node_modules/@types"     ]   },   "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
