npm - 未满足对等依赖 babel-core@5.8.38

Question

我试图安装 babel 和 babel 预设。但是我似乎遇到了阻止我安装的严重错误。

我输入了以下命令:

npm install --save-dev babel-core babel-loader babel-preset-es2015 babel-preset-stage-0 babel-preset-react

但它拒绝我并显示以下错误消息:

似乎是什么问题？

我还必须为 jspm 添加一个依赖项为了正确安装 babel-loader。

…
"dependencies": {
    "babel-loader": "^6.2.7",
    "jspm": "^0.16.48",
    …
}
