lib / lib.d.ts错误找不到名称“对象”

Question

任何人都可以提供帮助，我已经检查了很多次，实际上它在不同的系统中运行，但在我的系统中不工作。

Package.json

{

      "dependencies": {
        "@angular/animations": "~7.1.0",
        "@angular/common": "~7.1.0",
        "@angular/compiler": "~7.1.0",
        "@angular/core": "~7.1.0",
        "@angular/forms": "~7.1.0",
        "@angular/platform-browser": "~7.1.0",
        "@angular/platform-browser-dynamic": "~7.1.0",
        "@angular/router": "~7.1.0",
        "core-js": "^2.5.4",
        "rxjs": "~6.3.3",
        "tslib": "^1.9.0",
        "zone.js": "~0.8.26"
      },
      "devDependencies": {
        "@angular-devkit/build-angular": "~0.11.0",
        "@angular/cli": "~7.1.1",
        "@angular/compiler-cli": "~7.1.0",
        "@angular/language-service": "~7.1.0",
        "@types/node": "~8.9.4",
        "@types/jasmine": "~2.8.8",
        "@types/jasminewd2": "~2.0.3",
        "codelyzer": "~4.5.0",
        "jasmine-core": "~2.99.1",
        "jasmine-spec-reporter": "~4.2.1",
        "karma": "~3.1.1",
        "karma-chrome-launcher": "~2.2.0",
        "karma-coverage-istanbul-reporter": "~2.0.1",
        "karma-jasmine": "~1.1.2",
        "karma-jasmine-html-reporter": "^0.2.2",
        "protractor": "~5.4.0",

        "tslint": "~5.11.0",
        "typescript": "~3.2.1"
      }
    }

错误代码：

export class CityModel {
    name: string = '';

    constructor(values: Object) {
        Object.assign(this, values);
    }
}

here I am getting error
