ionic - 关于版本的混淆

Question

这是我从客户那里得到的package.json：

{
  "name": "ionic-hello-world",
  "author": "Ionic Framework",
  "homepage": "http://ionicframework.com/",
  "private": true,
  "scripts": {
    "clean": "ionic-app-scripts clean",
    "build": "ionic-app-scripts build",
    "ionic:build": "ionic-app-scripts build",
    "ionic:serve": "ionic-app-scripts serve"
  },
  "dependencies": {

        "@angular/forms": "4.1.3",
        "@angular/http": "4.1.3",
        "@angular/platform-browser": "4.1.3",
        "@angular/platform-browser-dynamic": "4.1.3",
        "@angular/platform-server": "4.1.3",

        "@types/jquery": "^3.2.6",
        "ajv": "^5.2.2",
        "ionic-angular": "^3.5.0",

        "grunt": "^1.0.1",
        "grunt-cli": "^1.2.0",

        "grunt-template": "^0.2.3",
        "typescript": "2.3.4"
  },
  "cordovaPlugins": [
    "ionic-plugin-keyboard",
    "cordova-plugin-whitelist",
    "cordova-plugin-console",
    "cordova-plugin-statusbar",
    "cordova-plugin-device",
    "cordova-plugin-splashscreen"
  ],
  "cordovaPlatforms": [
    "ios",
    {
      "platform": "ios",
      "version": "",
      "locator": "ios"
    }
  ],
  "description": "online_registration: An Ionic project"
}

当我尝试npm install 时，我收到了这个警告：

npm WARN @angular/animations@4.3.6 需要一个 @angular/core@4.3.6 但没有安装。 npm 警告 @angular/platform-server@4.1.3 需要一个对等点 @angular/animations@4.1.3 但没有安装。 npm 警告 @ionic-native/splash-screen@3.1.0 需要对等 @ionic-native/core@3.1.0 但没有安装。 npm 警告 @ionic-native/splash-screen@3.1.0 需要对等 @angular/core@2.4.8 但没有安装。 npm 警告 @ionic-native/splash-screen@3.1.0 需要一个 rxjs@5.0.1 但是 没有安装。 npm WARN grunt-template@0.2.3 需要一个对等点 grunt@~0.4.0 但没有安装。 npm 警告 ng2-translate@4.2.0 需要 @angular/core@^2.0.0 的对等点，但没有安装。 npm 警告 ng2-translate@4.2.0 需要 @angular/http@^2.0.0 的对等点，但 没有安装。

1. 这有多重要？

2. 然后我查看ionic info：

cli 包：(/Users/xxx/.nvm/versions/node/v6.9.1/lib/node_modules)

@ionic/cli-utils  : 1.9.2
ionic (Ionic CLI) : 3.9.2

全局包：

Cordova CLI : 6.4.0 

本地包：

@ionic/app-scripts : 2.1.4
Cordova Platforms  : android 6.1.2 ios 4.1.1
Ionic Framework    : ionic-angular 3.6.0

它似乎没有跟随package.json，ionic-angular 是^3.5.0。这是正确的吗？

您只需要删除node_modules 文件夹，然后运行npm i。希望一切都会好起来的。
