vue搭建安装环境

参考链接：https://www.cnblogs.com/ly-qingqiu/p/10330047.html

1.　　安装淘宝镜像

npm install -g cnpm --registry=https://registry.npm.taobao.org

注： 这里有可能会报错：operation not permitted, 这是因为没有用管理员身份打开终端，用管理员身份打开然后重新安装就可以了

2.　　安装webpack

npm install webpack -g

3.　　安装vue-cli

npm install vue-cli -g

4.　　创建项目

vue init webpack vuetest

5.　　进入新建的项目层

cd vuetest

6.　　安装项目依赖

npm install

7.　　安装vue路由模块vue-router和网络请求模块vue-resource

npm install vue-router vue-resource --save

8.　　启动项目

npm run dev

9.　　安装less

npm install less less-loader --save -dev

10.　　配置webpack config

配置前：

'use strict' const path = require('path')
const utils = require('./utils')
const config = require('../config')
const vueLoaderConfig = require('./vue-loader.conf') function resolve (dir) { return path.join(__dirname, '..', dir)
}

const createLintingRule = () => ({
  test: /\.(js|vue)$/,
  loader: 'eslint-loader',
  enforce: 'pre',
  include: [resolve('src'), resolve('test')],
  options: {
    formatter: require('eslint-friendly-formatter'),
    emitWarning: !config.dev.showEslintErrorsInOverlay
  }
})

module.exports = {
  context: path.resolve(__dirname, '../'),
  entry: {
    app: './src/main.js' },
  output: {
    path: config.build.assetsRoot,
    filename: '[name].js',
    publicPath: process.env.NODE_ENV === 'production'
      ? config.build.assetsPublicPath
      : config.dev.assetsPublicPath
  },
  resolve: {
    extensions: ['.js', '.vue', '.json'],
    alias: { 'vue/pre>: 'vue/dist/vue.esm.js', '@': resolve('src'),
    }
  },
  module: {
    rules: [
      ...(config.dev.useEslint ? [createLintingRule()] : []),
      {
        test: /\.vue$/,
        loader: 'vue-loader',
        options: vueLoaderConfig
      },
      {
        test: /\.js$/,
        loader: 'babel-loader',
        include: [resolve('src'), resolve('test'), resolve('node_modules/webpack-dev-server/client')]
      },
      {
        test: /\.(png|jpe?g|gif|svg)(\?.*)?$/,
        loader: 'url-loader',
        options: {
          limit: 10000,
          name: utils.assetsPath('img/[name].[hash:7].[ext]')
        }
      },
      {
        test: /\.(mp4|webm|ogg|mp3|wav|flac|aac)(\?.*)?$/,
        loader: 'url-loader',
        options: {
          limit: 10000,
          name: utils.assetsPath('media/[name].[hash:7].[ext]')
        }
      },
      {
        test: /\.(woff2?|eot|ttf|otf)(\?.*)?$/,
        loader: 'url-loader',
        options: {
          limit: 10000,
          name: utils.assetsPath('fonts/[name].[hash:7].[ext]')
        }
      }
    ]
  },
  node: { // prevent webpack from injecting useless setImmediate polyfill because Vue
    // source contains it (although only uses it if it's native).
    setImmediate: false, // prevent webpack from injecting mocks to Node native modules
    // that does not make sense for the client
    dgram: 'empty',
    fs: 'empty',
    net: 'empty',
    tls: 'empty',
    child_process: 'empty' }
}</pre>

配置后：

'use strict' const path = require('path')
const utils = require('./utils')
const config = require('../config')
const vueLoaderConfig = require('./vue-loader.conf')
const vuxLoader = require('vux-loader')
const webpack = require("webpack") // const webpackConfig = originalConfig // 原来的 module.exports 代码赋值给变量 webpackConfig

function resolve (dir) { return path.join(__dirname, '..', dir)
}

const webpackConfig = {
  context: path.resolve(__dirname, '../'),
  entry: {
    app: './src/main.js' },
  output: {
    path: config.build.assetsRoot,
    filename: '[name].js',
    publicPath: process.env.NODE_ENV === 'production'
      ? config.build.assetsPublicPath
      : config.dev.assetsPublicPath
  },
  resolve: {
    extensions: ['.js', '.vue', '.json'],
    alias: { 'vue/pre>: 'vue/dist/vue.esm.js', '@': resolve('src'),  //设置让@代表src目录  引用时候用到src目录的地方就可以直接用@代替
      'styles': resolve('src/assets/style'), 'img': resolve('src/assets/img'), 'jquery': 'jquery' }
  },
  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')]
      },
      {
        test: /\.(png|jpe?g|gif|svg)(\?.*)?$/,
        loader: 'url-loader',
        options: {
          limit: 10000,
          name: utils.assetsPath('img/[name].[hash:7].[ext]')
        }
      },
      {
        test: /\.(mp4|webm|ogg|mp3|wav|flac|aac)(\?.*)?$/,
        loader: 'url-loader',
        options: {
          limit: 10000,
          name: utils.assetsPath('media/[name].[hash:7].[ext]')
        }
      },
      {
        test: /\.(woff2?|eot|ttf|otf)(\?.*)?$/,
        loader: 'url-loader',
        options: {
          limit: 10000,
          name: utils.assetsPath('fonts/[name].[hash:7].[ext]')
        }
      }
    ]
  },
  node: { // prevent webpack from injecting useless setImmediate polyfill because Vue
    // source contains it (although only uses it if it's native).
    setImmediate: false, // prevent webpack from injecting mocks to Node native modules
    // that does not make sense for the client
    dgram: 'empty',
    fs: 'empty',
    net: 'empty',
    tls: 'empty',
    child_process: 'empty' }
}

module.exports = vuxLoader.merge(webpackConfig, {
  plugins: [ 'vux-ui', new webpack.ProvidePlugin({
      jQuery: "jquery",
      $: "jquery" })
  ]
})</pre>

11.如果需要使用vux等插件 ，在安装依赖即可，如下：

npm install vux --save

然后安装vux预处理器

npm install vux-loader --save -dev

12.　这一步是为了正确进行语言读取，就是将yaml有效的转换成json

npm install yaml-loader --save -dev         

13. 最后在运行一下项目

 npm run dev
