需要npm install --save-dev babel-preset-stage-1
然后将根目录下的.babelrc中的"stage-3" 修改为 “stage-1” 就可以使用修饰器了

@javaLuo 这个需要我自己配置吗？ 还是说您已经配置好了 ，我可以直接用？

[wangjunwei910208]

@javaLuo 根据您的提示，修改后，这样编辑，如下：
@connect(
state => ({
num: state.app.num,
}),
dispatch =>({
})
)
class Mytest extends React.Component {
constructor(props) {
super(props);
this.state = {
};
}
render() {
const {num} = this.props;
console.log(num);
return (

)
}
}
运行项目时提示我识别不了@

[javaLuo]

重新npm run dll 试试

[wangjunwei910208]

@javaLuo 还是 报这个错
ERROR in ./src/a_container/test/index.js

[javaLuo]

额...不是吧，我这边测试可以识别@了

[wangjunwei910208]

@javaLuo 我从新拷贝你的项目 然后按您的指示，报如下错误：
ERROR in ./src/a_container/test/index.js

However, if you need to use them you can install the legacy decorators transform with:

npm install babel-plugin-transform-decorators-legacy --save-dev

and add the following line to your .babelrc file:

{
"plugins": ["transform-decorators-legacy"]
}

然后我这样:
npm install babel-plugin-transform-decorators-legacy --save-dev

接着修改.babelrc
{
"presets": ["es2015", "stage-1", "react"],
"plugins": [
"transform-decorators-legacy",
["import", {
"libraryName": "antd",
"style": "css"
}
]
]
}
最后运行时还是报错

[javaLuo]

我更新了代码，重新上传了。你再试试。
暂时取消了eslint代码检测。eslint现在的版本不支持decorator

[wangjunwei910208]

@javaLuo 您好，现在能识别@了，但是运行后会报这个错，如下：
vendor.dll.js:34 Uncaught TypeError: Cannot read property 'location' of undefined

再次麻烦您给指导下了

重新拉一下代码
重新install
那是react-router版本不兼容
暂时没有升级到react-router4.0
