vue全家桶安装以及修改webpack配置新增vue项目启动方式

一、安装node环境（自带npm）

二、替换下载源

// 淘宝 NPM 镜像

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

三、全局安装vue-cli脚手架

npm install --global vue-cli

四、vue2.* webpack模板下载

vue init webpack vue_project

五、安装vuex

npm install vuex --save

在main.js中注入vuex

// vuex

import Vuex from 'vuex'

Vue.use(Vuex)

六、安装axios

npm install axios --save

在main.js导入并全局使用

// axios请求

import axios from "axios"

Vue.prototype.$axios = axios

七、安装elementUI

npm install element-ui --save

在main.js中引入elementUI

// element样式框架

import ElementUI from 'element-ui'
import 'element-ui/lib/theme-chalk/index.css'

Vue.use(ElementUI)

八、vue项目使用sass

npm install sass-loader --save-dev

npm install node-sass --save-dev

//连写
npm install sass-loader node-sass --save-dev

想要使用sass，需要修改build目录下的webpack.base.conf.js文件，增加以下规则：

{

  test: /\.sass$/,

  loaders: ['style', 'css', 'sass',"scss"]

}

在组件中使用sass语法

<style lang="scss">

  $size:50px;

  html {

    font-size: $size;

  }

</style>

或者外部引用：

<style lang="scss">

  @import "./main.scss"

  // 或者

  // @import url(./main.scss);

</style>

若出现：

Modele build failed: TypeError: this.getResolve is not a function at Object.loader...

是因为sass-loader版本过高，webpack编译不过去，降级即可

"sass-loader": "^8.0.0"，更换成"sass-loader": "^7.3.1",

九、修改webpack配置，新增项目启动方式

以 pred 为例：

1，首先更改package.json配置

2，在build目录下增加pred.js,内容和build.js文件相同，更改以下三处变量即可

3.修改build目录下webpack.prod.conf.js配置，替换如下代码：

'use strict'

const path = require('path')

const utils = require('./utils')

const webpack = require('webpack')

const config = require('../config')

const merge = require('webpack-merge')

const baseWebpackConfig = require('./webpack.base.conf')

const CopyWebpackPlugin = require('copy-webpack-plugin')

const HtmlWebpackPlugin = require('html-webpack-plugin')

const ExtractTextPlugin = require('extract-text-webpack-plugin')

const OptimizeCSSPlugin = require('optimize-css-assets-webpack-plugin')

const UglifyJsPlugin = require('uglifyjs-webpack-plugin')

/** 删除内容

  const env = process.env.NODE_ENV === 'testing'

  ? require('../config/test.env')

  : require('../config/prod.env')

*/

// 替换成

  const ENV_MAP = {

    'testing': require('../config/test.env'),

    'production': require('../config/prod.env'),

    'pred': require('../config/pred.env')

  }

  const env = process.env.NODE_ENV = ENV_MAP[process.env.NODE_ENV];

4.在config目录新增 pred.env.js文件，内容如下

'use strict'

module.exports = {

  NODE_ENV: '"pred"'

}

5.修改config目录下的index.js，复制build对象并修改成pred

build: {

    // Template for index.html

    index: path.resolve(__dirname, '../dist/index.html'),

    // Paths

    assetsRoot: path.resolve(__dirname, '../dist'),

    assetsSubDirectory: 'static',

    assetsPublicPath: '/',

    /**

     * Source Maps

     */

    productionSourceMap: true,

    // https://webpack.js.org/configuration/devtool/#production

    devtool: '#source-map',

    // Gzip off by default as many popular static hosts such as

    // Surge or Netlify already gzip all static assets for you.

    // Before setting to `true`, make sure to:

    // npm install --save-dev compression-webpack-plugin

    productionGzip: false,

    productionGzipExtensions: ['js', 'css'],

    // Run the build command with an extra argument to

    // View the bundle analyzer report after build finishes:

    // `npm run build --report`

    // Set to `true` or `false` to always turn it on or off

    bundleAnalyzerReport: process.env.npm_config_report

  },

  pred: {

    // Template for index.html

    index: path.resolve(__dirname, '../dist/index.html'),

    // Paths

    assetsRoot: path.resolve(__dirname, '../dist'),

    assetsSubDirectory: 'static',

    assetsPublicPath: '/',

    /**

     * Source Maps

     */

    productionSourceMap: true,

    // https://webpack.js.org/configuration/devtool/#production

    devtool: '#source-map',

    // Gzip off by default as many popular static hosts such as

    // Surge or Netlify already gzip all static assets for you.

    // Before setting to `true`, make sure to:

    // npm install --save-dev compression-webpack-plugin

    productionGzip: false,

    productionGzipExtensions: ['js', 'css'],

    // Run the build command with an extra argument to

    // View the bundle analyzer report after build finishes:

    // `npm run build --report`

    // Set to `true` or `false` to always turn it on or off

    bundleAnalyzerReport: process.env.npm_config_report

  }

6，控制台输入 npm run pred，看到如下内容即成功：
