 "@angular/router": ">=5.2.9",
 "ng-packagr": "^3.0.6",
 "rxjs-compat": "^6.2.2"

请将"typescript": "3.1.1"的依赖项添加为：

"dependencies": {
  ...
  "typescript": "3.1.1"
  ...
}

注意：您可以使用任何其他版本

您的package.json应该如下所示：

"dependencies": {
    "@angular/common": "^5.0.0",
    "@angular/compiler": "^5.0.0",
    "@angular/core": "^5.0.0",
    "@angular/forms": "^5.0.0",
    "@angular/http": "^5.0.0",
    "@angular/platform-browser": "^5.0.0",
    "@angular/platform-browser-dynamic": "^5.0.0",
    "@angular/router": "^5.0.0",
    "core-js": "^2.4.1",
    "rxjs": "^5.5.2",
    "zone.js": "^0.8.14"
},
"devDependencies": {
    "@angular/cli": "1.5.0",
    "@angular/compiler-cli": "^5.0.0",
    "@angular/language-service": "^5.0.0",
    "@types/node": "~6.0.60",
    "codelyzer": "~3.2.0",
    "ts-node": "~3.2.0",
    "tslint": "~5.7.0",
    "typescript": "~2.4.2"
