无效的名字@ angular / common：npm

Question

我正在尝试使用Ionic2，但在尝试为Ionic2安装默认的npm软件包时遇到了一些错误。我尝试运行以下命令并收到以下错误：

npm install @angular/common like here

还尝试了this解决方案，但遇到了同样的错误。

package.json文件内容：

{
  "dependencies": {
    "@angular/compiler": "^2.0.0-rc.1",
    "@angular/core": "^2.0.0-rc.1",
    "@angular/http": "^2.0.0-rc.1",

尝试此命令

npm install -g npm

试试这个可以帮到你： -

npm install @angular/common@2.0.0-rc.1 --save

或者您可以提及您想要的版本
