Question

我试图安装babel和babel预设。但我似乎遇到了一个阻止我安装的严重错误。

我输入以下命令：

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

但它拒绝了我，并出现以下错误消息：

似乎是什么问题？

我还必须为jspm添加一个依赖项，以便正确安装babel-loader。

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