vue2.0+element+node+webpack搭建的一个简单的后台管理界面

Posted 2020-10-29 hzp-tt

 1.检查本地是否安装node：node -v  

                      

       如果没有安装从node官网上下载相应的node，安装成功即可。

      2.检查本地npm版本：npm -v，如果版本太低可以通过：npm install -g npm进行升级

                     

      3.全局安装webpack：npm install webpack -g

      4.安装vue脚手架：npm install vue-cli -g

      5.新建空文件夹，根据模板创建项目：

             vue init webpack-simple 工程名字<工程名字不能用中文>

             或者创建 vue1.0 的项目： vue init webpack-simple#1.0 工程名字<工程名字不能用中文>

             会有一些初始化的设置，如下输入:

       Target directory exists. Continue? (Y/n)直接回车默认(然后会下载 vue2.0模板，这里可能需要连代理)

       Project name (vue-test)直接回车默认

       Project description (A Vue.js project) 直接回车默认

       Author 写你自己的名字

       Use sass 小颖的这个demo要用sass所以，小颖选的yes，大家可以根据自己的需求选择yes or no

在你的项目根目录下，运行：npm run dev之后，会自动打开你的默认浏览器：http://localhost:8080/    效果如下：

          

项目目录：

------------------mydemo

--------------------------src

----------------------------------page

--------------------------------------------------menu1

---------------------------------------------------------------------menuTab.vue

--------------------------------------------------menu2

---------------------------------------------------------------------menuTable.vue

--------------------------------------------------404.vue

--------------------------------------------------home.vue

--------------------------------------------------login.vue

----------------------------------App.vue

----------------------------------main.js

----------------------------------router.js

--------------------------favicon.ico

--------------------------index.html

--------------------------package.json

--------------------------webpack.config.js

然后我们将自己想要的页面什么的慢慢加进去：

1.在根目录下添加favicon.ico图标，小颖是直接把：mydemo/src/assets下的logo.png改成favicon.ico。

2.在webpack.config.js中添加以下代码：

                                 

                                

然后我们再执行一次：npm run dev

然后就报错啦报错啦：

解决方法：

     执行npm install html-webpack-plugin -save-v

3.在index.html中引入favicon.ico图标：

<link rel="shortcut icon"  href="favicon.ico"/>

4.新增所需vue文件和js文件：

5.引入所需的npm：element-ui、vue-router、font-awesome、style-loader。

最后呢我们一起来看看具体哪些重要的vue文件和js文件代码是什么样子的。

代码来啦：

webpack.config.js

var path = require(‘path‘)
var webpack = require(‘webpack‘)

                    loaders: {
                        // Since sass-loader (weirdly) has SCSS as its default parse mode, we map
                        // the "scss" and "sass" values for the lang attribute to the right configs here.
                        // other preprocessors should work out of the box, no loader config like this necessary.
                        ‘scss‘: ‘vue-style-loader!css-loader!sass-loader‘,
                        ‘sass‘: ‘vue-style-loader!css-loader!sass-loader?indentedSyntax‘
                    }
                    // other vue-loader options go here    小颖在这里http://www.cnblogs.com/yingzi1028/p/6925387.html

                }
            },
            {

                loader: ‘file-loader‘,
                options: {
                    name: ‘[name].[ext]?[hash]‘
                }
            }
