angular 2未满足的对等依赖项

Question

我有一个通过CLI创建的angular2项目，我的package.json如下所示：

{
  "name": "thesis-proto",
  "version": "0.0.0",
  "license": "MIT",
  "angular-cli": {},
  "scripts": {
    "ng": "ng",
    "start": "ng serve",
    "test": "ng test",
    "pree2e": "webdriver-manager update --standalone false --gecko false",
    "e2e": "protractor"
  },
  "private": true,
  "dependencies": {
    "@angular/common": "^2.3.1",
    "@angular/compiler": "^2.3.1",
    "@angular/core": "^2.3.1",
    "@angular/forms": "^2.3.1",
    "@angular/http": "^2.3.1",
    "@angular/platform-browser": "^2.3.1",
    "@angular/platform-browser-dynamic": "^2.3.1",
    "@angular/router": "^3.3.1",
    "@ng-bootstrap/ng-bootstrap": "^1.0.0-alpha.25",
    "angular2-mdl": "^2.13.2",
    "core-js": "^2.4.1",
    "material-design-lite": "^1.3.0",
    "mdl-stepper": "^1.1.6",
    "ng2-tour": "^0.1.5",
    "rxjs": "^5.0.1",
    "ts-helpers": "^1.1.1",
    "zone.js": "^0.7.2"
  },
  "devDependencies": {
    "@angular/compiler-cli": "^2.3.1",
    "@types/jasmine": "2.5.38",
    "@types/node": "^6.0.42",
    "angular-cli": "1.0.0-beta.28.3",
    "codelyzer": "~2.0.0-beta.1",
    "jasmine-core": "2.5.2",
    "jasmine-spec-reporter": "2.5.0",
    "karma": "1.2.0",
    "karma-chrome-launcher": "^2.0.0",
    "karma-cli": "^1.0.1",
    "karma-jasmine": "^1.0.2",
    "karma-remap-istanbul": "^0.2.1",
    "protractor": "~4.0.13",
    "ts-node": "1.2.1",
    "tslint": "^4.3.0",
    "typescript": "~2.0.3"
  }
}

当我收到以下错误时，我正在尝试安装ng2-tour（https://isaacplmann.github.io/ng2-tour/）：

我到底应该做什么？我不想破坏任何现有的依赖项。

Answer 1

如果不满足package.json文件中指定的一个或多个模块的依赖项，则抛出UNMET PEER DEPENDENCY错误。仔细检查警告并使用正确版本的依赖项更新package.json文件。

然后运行

rm -rf node_modules/
npm cache clean
npm install

这将正确安装所有必需的依赖项。
