尝试运行项目时在 ng serve 上显示错误

Question

我是 angular.I 的新手，安装了最新的 Node.js 并全局安装了 Angular CLI。我刚刚从 github 克隆了项目并尝试使用 ng serve 运行 angular 项目，但它显示错误：

我的package.json是：

{
  "name": "my-dream-app",
  "version": "0.0.0",
  "scripts": {
    "ng": "ng",
    "start": "ng serve",
    "build": "ng build",
    "test": "ng test",
    "lint": "ng lint",
    "e2e": "ng e2e"
  },
  "private": true,
  "dependencies": {
    "@angular/animations": "^7.0.4",
    "@angular/common": "^7.0.4",
    "@angular/compiler": "^7.0.4",
    "@angular/core": "^7.0.4",
    "@angular/forms": "^7.0.4",
    "@angular/http": "^7.0.4",
    "@angular/platform-browser": "^7.0.4",
    "@angular/platform-browser-dynamic": "^7.0.4",
    "@angular/router": "^7.0.4",
    "core-js": "^2.6.9",
    "rxjs": "~6.3.3",
    "zone.js": "^0.8.29"
  },
  "devDependencies": {
    "@angular/compiler-cli": "^7.0.4",
    "@angular/language-service": "^7.0.4",
    "@types/jasmine": "^2.8.16",
    "@types/jasminewd2": "^2.0.6",
    "@types/node": "~8.9.4",
    "codelyzer": "~4.5.0",
    "jasmine-core": "~2.99.1",
    "jasmine-spec-reporter": "~4.2.1",
    "karma": "~3.0.0",
    "karma-chrome-launcher": "~2.2.0",
    "karma-coverage-istanbul-reporter": "^2.0.6",
    "karma-jasmine": "~1.1.2",
    "karma-jasmine-html-reporter": "^0.2.2",
    "protractor": "^5.4.2",
    "ts-node": "~7.0.0",
    "tslint": "~5.11.0",
    "typescript": "^3.1.6"
  }
}

我不知道什么不匹配，我怎样才能将 angualr CLI 与克隆的项目相匹配？

正如您所说，您只是 downloaded/cloned 从 github 开始并立即尝试运行吗？如果是这样，您可能忘记了运行 "npm install"，这将为 github-项目安装必要的库。
