Babel 转码 es6项目问题失败?

Question

全局执行是没有问题

babel ./ -d babel

但是放到script里面就不行了

package.json

//...
"devDependencies": {
"babel": "^6.5.2",
    "babel-cli": "^6.14.0",
    "babel-core": "^6.18.2",
    "babel-eslint": "^6.1.0",
    "babel-loader": "^6.2.7",
    "babel-polyfill": "^6.9.1",
    "babel-preset-es2015": "^6.9.0",
    "babel-preset-react": "^6.5.0",
    "babel-preset-stage-0": "^6.5.0",
    "babel-preset-stage-2": "^6.18.0",
    "babel-preset-stage-3": "^6.17.0",
},
"scripts": {
//...
    "build": "babel ./ -d ./babel"
//...
  },
//...

.babelrc

{
    "presets": [
        "es2015",
        "react",
        "stage-2"
    ]
}

错误提示

Answer 1

试试加一个 compact: false

Answer 2

貌似windows下的路径问题，用标准的babel src -d lib试试。

Answer 3

问题解决了，虽然来回答的人都没能帮我解决，但还是非常感谢能抽空过来回答！
是这样的，我google了一下把babel-cli babel-core都重新装了一遍,然后把bable删除了问题就暂时解决了(有点知其然不知其所以然的感觉,谁知道原理希望不吝赐教)
过程中发现两个问题

1. package.json'生成'的文件不能被正常require(),可以使用babel-plugin-add-module-exports来解决

2. 使用koa + node.js搭建的服务器解析后会出现这个下面错误

var _ref = _asyncToGenerator(regeneratorRuntime.mark(function _callee(ctx, next) {
                                     ^

ReferenceError: regeneratorRuntime is not defined

原因因为阮老师原话:

Babel默认只转换新的JavaScript句法（syntax），而不转换新的API，比如Iterator、Generator、Set、Maps、Proxy、Reflect、Symbol、Promise等全局对象，以及一些定义在全局对象上的方法（比如Object.assign）都不会转码。
解决办法也很简单只要在头部加上require('babel-polyfill');或者import 'babel-polyfill';就可以了

.babelrc

{
    "presets": [
        "es2015",
        "react",
        "stage-2"
    ],
    "plugins": [
        "add-module-exports"
    ]
}

package.json

{
//...
    "devDependencies": {
        "babel-cli": "^6.14.0",
        "babel-core": "^6.18.2",
        "babel-eslint": "^6.1.0",
        "babel-loader": "^6.2.7",
        "babel-plugin-add-module-exports": "^0.2.1",
        "babel-polyfill": "^6.9.1",
        "babel-preset-es2015": "^6.9.0",
        "babel-preset-react": "^6.5.0",
        "babel-preset-stage-0": "^6.5.0",
        "babel-preset-stage-2": "^6.18.0",
        "babel-preset-stage-3": "^6.17.0"
    }
//...
}
