Uncaught SyntaxError: Unexpected token export

Question

我在我的项目中使用了 create-react-app。我收到

错误

Uncaught SyntaxError: Unexpected token export

错误在此代码中

export const ENGLISH = {
  lang: 'en',
  messages: {
      'nav.translatedMessage': 'Social',
  }
};

我尝试安装 babel-preset-es2015 和 babel-preset-stage-0。我还把 babel dict/object 包含在 package.json 作为

"babel": {
    "presets": [
      "es2015",
      "stage-0"
    ]
  },

我仍然遇到错误。

Answer 1

我在 create-react-app 的 README.md 上得到了答案。上面写着

You may create subdirectories inside src. For faster rebuilds, only files inside src are processed by Webpack.
You need to put any JS and CSS files inside src, or Webpack won’t see them.

Answer 2

我认为是因为逗号

export const ENGLISH = {
       lang: 'en',
       messages: {
           'nav.translatedMessage': 'Social'
       }
};

尝试这样做！
