I have the same problem

What Node version are you using? Try using v9.7.1 (I suggest using nvm for easier switching between Node versions)

[amiralisahraei]

Thanks for answering but i test this version of node too but nothing changed :(
Has you run this project without any problem ?

我出现这个问题的原因是因为在vue中使用webpack进行初始化项目，代码中 使用require('web3.js'); 就会报错。
大概原因是因为没有解析到扩展运算符（...），所以只需要让程序解析就好了。

我的解决方法是：在build/webpack.base.conf.js文件中，配置：resolve('你的第三方库路径')

 module: {
    rules: [
      {
        test: /\.vue$/,
        loader: 'vue-loader',
        options: vueLoaderConfig
      },
      {
        test: /\.js$/,
        loader: 'babel-loader',
        include: [resolve('src'), 
          resolve('test'), 
          resolve('node_modules/webpack-dev-server/client'),
         resolve('你的第三方库路径')
        ]
      },
      {
        test: /\.(png|jpe?g|gif|svg)(\?.*)?$/,
        loader: 'url-loader',
        options: {
          limit: 10000,
          name: utils.assetsPath('img/[name].[hash:7].[ext]')
        }
      },

例如我web3.js出现了问题，我的修改的配置是：

  module: {
    rules: [
      {
        test: /\.vue$/,
        loader: 'vue-loader',
        options: vueLoaderConfig
      },
      {
        test: /\.js$/,
        loader: 'babel-loader',
        include: [resolve('src'), resolve('test'),
          resolve('node_modules/webpack-dev-server/client'),
          resolve('node_modules/web3-eth-accounts/lib'),
          resolve('node_modules/web3-core-helpers/lib'),
          resolve('node_modules/web3-core-method/lib'),
          resolve('node_modules/web3-eth-contract/lib')
        ]
      },

然后去修改.babelrc文件：

{
  "presets": [
    "stage-2"
  ]
}

我问题就这样解决了
