离子 2 ： "npm install"后发出警告

Question

我使用 Ionic v2.1.8，当我运行命令"npm install"时，我有很多这样的警告：

C:xampphtdocsAppFineMobile>npm install

我的包.json 文件：

  "cordovaPlatforms": [],

}

我不明白，因为我的node_modules文件夹中有这些模块。当我尝试安装其中一个时，我会在另一个 npm 安装中保持警告。

我真的不明白，我不知道如何解决这个问题

您只需要将所有angular packages更新为 2.4.8 。此外，您的ionic-angular包是2.2.0。

改变：

"@angular/common": "^2.4.8",
"@angular/compiler": "^2.4.8",
"@angular/compiler-cli": "^2.4.8",
"@angular/core": "^2.4.8",
"@angular/forms": "^2.4.8",
"@angular/http": "^2.4.8",
"@angular/platform-browser": "^2.4.8",
"@angular/platform-browser-dynamic": "^2.4.8",
"@angular/platform-server": "^2.4.8",

也

"rxjs": "^5.0.1",
"zone.js" :"0.7.2"

在出现问题时清除node_modules文件夹，然后执行以下操作： npm install
