生产模式下仍然提示“开发模式”

Question

问题描述

在 webpack.config.js 里加上 vue: 'vue/dist/vue.js' 后，npm run build 仍然会出现：

You are running Vue in development mode.
Make sure to turn on production mode when deploying for production.
See more tips at https://vuejs.org/guide/deployment.html

把这句去除后就提示

[Vue warn]: You are using the runtime-only build of Vue where the template compiler is not available. Either pre-compile the templates into render functions, or use the compiler-included build.

webpack.config.js 代码

const resolve = require('path').resolve
const webpack = require('webpack')
const HtmlWebpackPlugin = require('html-webpack-plugin')
const url = require('url')
const publicPath = ''

module.exports = (options = {}) => ({
  entry: {
    vendor: './src/vendor',
    index: './src/main.js'
  },
  output: {
    path: resolve(__dirname, 'dist'),
    filename: options.dev ? '[name].js' : '[name].js?[chunkhash]',
    chunkFilename: '[id].js?[chunkhash]',
    publicPath: options.dev ? '/assets/' : publicPath
  },
  module: {
    rules: [{
        test: /\.vue$/,
        use: ['vue-loader']
      },
      {
        test: /\.js$/,
        use: ['babel-loader'],
        exclude: /node_modules/
      },
      {
        test: /\.css$/,
        use: ['style-loader', 'css-loader', 'postcss-loader']
      },
      {
        test: /\.(png|jpg|jpeg|gif|eot|ttf|woff|woff2|svg|svgz)(\?.+)?$/,
        use: [{
          loader: 'url-loader',
          options: {
            limit: 10000
          }
        }]
      }
    ]
  },
  plugins: [
    new webpack.optimize.CommonsChunkPlugin({
      names: ['vendor', 'manifest']
    }),
    new HtmlWebpackPlugin({
      template: 'src/index.html'
    })
  ],
  resolve: {
    alias: {
      '~': resolve(__dirname, 'src'),
      vue: 'vue/dist/vue.js',
    },
    extensions: ['.js', '.vue', '.json', '.css']
  },
  devServer: {
    host: '127.0.0.1',
    port: 8010,
    proxy: {
      '/api/': {
        target: 'http://127.0.0.1:8080',
        changeOrigin: true,
        pathRewrite: {
          '^/api': ''
        }
      }
    },
    historyApiFallback: {
      index: url.parse(options.dev ? '/assets/' : publicPath).pathname
    }
  },
  devtool: options.dev ? '#eval-source-map' : '#source-map'
})

有一个建议哈，第一呢，可以用老版本的 vue-cli 来创建项目，它会自定给你分环境配置 webpack.config 文件，有 base production dev 等

然后再配置文件里面可以定义：(我猜你用的还不是 webpack4)

new webpack.DefinePlugin({
      'process.env.NODE_ENV': JSON.stringify('production')
    })

如果是 4 的话：配置 mode

module.exports = {
  mode: 'production'
}
