UNMET PEER DEPENDENCY babel-core@5.8.38

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

但它拒绝我以下错误消息:

我还必须添加一个依赖项，jspm以便正确安装 babel-loader。

\xe2\x80\xa6\n"dependencies": {\n    "babel-loader": "^6.2.7",\n    "jspm": "^0.16.48",\n    \xe2\x80\xa6\n}\n
