错误：缺少类属性转换 [英] Error: Missing class properties transform

问题描述

错误：缺少类属性转换

Test.js ：

export class Test extends Component {
  constructor (props) {
    super(props)
  }

  static contextTypes = {
    router: React.PropTypes.object.isRequired
  }

.babelrc ：

{
  "presets": ["es2015", "react", "stage-0"],
  "plugins": ["transform-class-properties"]
}

package.json ：

"babel-core": "^6.5.1",
"babel-eslint": "^4.1.8",
"babel-loader": "^6.2.2",
"babel-plugin-react-transform": "^2.0.0",
"babel-plugin-transform-class-properties": "^6.5.2",
"babel-preset-es2015": "^6.5.0",
"babel-preset-react": "^6.5.0",
"babel-preset-stage-0": "^6.5.0",
"babel-register": "^6.5.2",

我已经在网上搜索了一下ll fixs around around：升级到babel6，将stage-0的顺序切换为es2015之后。我已经完成了所有这些。

I have scoured the web and all fixes revolve around: Upgrading to babel6, switching the order of "stage-0" to be after "es2015". All of which I have done.

推荐答案

好的，终于弄明白了，在我的 webpack.config中.js 我有：

OK, finally figured this out, in my webpack.config.js I had:

module: {
    loaders: [
      {
        test: /\.js?$/,
        exclude: /(node_modules|bower_components)/,
        loaders: [
          'react-hot',
          'babel?presets[]=react,presets[]=es2015,presets[]=stage-0'
        ]
      }
    ]
  }

'babel？presets [] = stage-0，presets [] = react，presets [] = es2015'

必须以与 .babelrc 相同的方式对待，切换阶段0在es2015之后，它完美地编译。

Has to be treated in the same way as .babelrc, switched stage-0 to be after es2015 and it compiles perfectly.
