基础环境搭建
下载nvm安装包
安装目录为：C:\Users\admin\AppData\Local\nvm
C:\nvm4w\nodejs
重启，使环境变量生效
安装nodejs:
nvm install 16.12.0
切换到刚安装的低版本,因为有可能装了不同版本，nvm use 16.12.0
验证版本：
node -v
npm -v
将安装的版本设为默认版本（新终端自动生效）
nvm alias default 16.12.0
常用补充命令
命令 作用
nvm list / nvm ls 查看本地已安装的所有 node 版本
nvm uninstall 20.19.4 卸载旧的高版本（切换后可选）
nvm current 查看当前生效的 node 版本
设置淘宝镜像：npm config set registry http://registry.npm.taobao.org/
Npm install
下载vue-admin-template-4.4.0
官方下载地址：https://panjiachen.github.io/vue-element-admin-site/zh/
将它解压到一个没有中文字的路径下（避免出现奇怪的问题）
用VScode打开
进入终端，输入 npm install
注意要在package.json这个同级的目录中执行npm install
安装依赖，然后 npm run dev
更改配置文件：vue.config.js
'use strict'
const path = require('path')
const defaultSettings = require('./src/settings.js')
function resolve(dir) {
return path.join(__dirname, dir)
}
const name = defaultSettings.title || 'vue Admin Template' // page title
// If your port is set to 80,
// use administrator privileges to execute the command line.
// For example, Mac: sudo npm run
// You can change the port by the following methods:
// port = 9528 npm run dev OR npm run dev --port = 9528
const port = process.env.port || process.env.npm_config_port || 9528 // dev port
// All configuration item explanations can be find in https://cli.vuejs.org/config/

}生产和开发环境的配置
文件：.env.development
# just a flag
ENV = 'development'
# base api
VUE_APP_BASE_API = 'http://localhost:9999'文件：.env.production
# just a flag
ENV = 'production'
# base api
VUE_APP_BASE_API = 'http://localhost:9999'在终端中输入打包命令：
-
打包正式环境
- npm run build:prod
会生成dist文件夹。
前后端对接：
User.js，把URL 改成下面的代码：
import request from '@/utils/request'
export function login(data) {
return request({
url: '/user/login',
method: 'post',
data
})
}
export function getInfo(token) {
return request({
url: '/user/info',
method: 'get',
params: { token }
})
}
export function logout() {
return request({
url: '/user/logout',
method: 'post'
})
}
