反应：运行npm时意外的令牌导入开始

Question

我有一个React项目，当我在chrome中打开它的路径时在本地工作。然而，当试图部署到Heroku的（或运行npm start），我得到这个错误：

import React from 'react'; 
^^^^^^ 
SyntaxError: Unexpected token import 

我已经冲刷的StackOverflow和Heroku的支持页面无济于事。

这里是我的package.json：

{ 
    "name": "my-app-name", 
    "version": "1.0.0", 
    "description": "", 
    "main": "index.js", 
    "scripts": { 
    "test": "echo \"Error: no test specified\" && exit 1", 
    "webpack": "webpack", 
    "start": "node ./my-app-name.jsx", 
    "postinstall": "webpack" 
    }, 
    "keywords": [], 
    "author": "", 
    "license": "ISC", 
    "dependencies": { 
    "babel-cli": "^6.24.0", 
    "babel-core": "^6.24.0", 
    "babel-loader": "^6.4.1", 
    "babel-preset-es2015": "^6.24.0", 
    "babel-preset-react": "^6.23.0", 
    "react": "^15.4.2", 
    "react-dom": "^15.4.2", 
    "react-redux": "^5.0.3", 
    "react-router": "^4.0.0", 
    "react-router-dom": "^4.0.0", 
    "redux": "^3.6.0", 
    "webpack": "^2.3.2" 
    }, 
    "engines": { 
    "node": "6.2.1", 
    "npm": "4.4.4" 
    } 
} 

而且我webpack.config.js：

module.exports = { 
    entry: "./my-app-name.jsx", 
    output: { 
    filename: "./bundle.js" 
    }, 
    module: { 
    loaders: [ 
     { 
     test: [/\.jsx?$/, /\.js?$/], 
     exclude: /(node_modules)/, 
     loader: 'babel-loader', 
     query: { 
      presets: ['es2015', 'react'] 
     } 
     } 
    ] 
    }, 
    devtool: 'source-map', 
    resolve: { 
    extensions: ["*",".js", ".jsx" ] 
    } 
}; 

我的节点和NPM版本中的package.json列出的相同。我进行了三重检查，确保所有内容都已正确安装，并且其他StackOverflow答案都没有帮助。当然，它必须是巴贝尔的某种问题（由于它不承认import），但我无法弄清楚它是什么。

Answer 1

my-app-name.jsx不是编译构建。而不是node ./my-app-name.jsx，你需要指出节点开始像这样的运输生成node ./bundle.js
