news 2026/1/20 13:18:14

1.安装nodejs

下载链接https://cdn.npmmirror.com/binaries/node/v18.18.0/node-v18.18.0-x64.msi

进入cmd 命令行模式管理员身份运行

输入（node -v）能看到版本号

npm config set prefix "C:\Program Files\nodejs" 默认路径

npm config set prefix " 写你安装的路径 "

切换npm 的淘宝镜像（npm config set registry https://registry.npm.taobao .org）

2.安装vue/cli

输入（ npm install -g @vue/cli ）

出现错误根据错误搜索

安装好了输入（nue ui）

浏览器自动打开（http://localhost:8000）这个网页我们在这里创建项目

桌面创建一个文件夹复制路径 get 关掉

路径改好了输入项目名称点击创建

点击创建就行了

然后刚刚启动vue 的cmd 窗口能看到创建项目

等几分钟完成

启动项目

导入vscode 搜索框输入npm

选择第一个然后就启动了

看到这个已经启动了

打开浏览器输入 http://localhost:8080/然后看到vue的见面

先停掉项目

进入vscode终端按ctrl+c

安装element

vscode 里面项目文件夹（右键）点击（在集成终端中打开）

输入 npm install element-ui@2.15.3

出现错误根据错误搜索

项目文件里看到这个文件 "node_modules\element-ui"已经安装好了

引入elemnt

vue.config.js

const { defineConfig } = require('@vue/cli-service')
module.exports = defineConfig({transpileDependencies: true,devServer:{port:7000}
})

main.js 文件

import Vue from 'vue'
import App from './App.vue'
import router from './router'
// eliment引入的
import ElementUI from 'element-ui'
import 'element-ui/lib/theme-chalk/index.css'Vue.config.productionTip = false
// eliment引入的
Vue.use(ElementUI);new Vue({router,render: h => h(App)
}).$mount('#app')

自己创建一个文件 src\views\名字文件夹的\ElementView.vue 注意大小

app.文件

根据错误提示，在命令行中加入–legacy-peer-deps，由于vue与vue-router版本兼容的问题，需要在安装语句后加入需要下载vue-router版本，不然会下载最新的vue-router版本。

npm install --legacy-peer-deps vue-router@4.0.13

也有可能因为是你要下载的router版本过高，如果下载版本过高，在启动项目时会报错，可以下载低版本的vue-router

npm install vue-router@3.1.3 --save-dev

最后在package.json文件中查看是否下载成功

npm install element-ui@2.15.3

错误

删除node_modules和package-lock.json，然后运行
```
npm install
```
或尝试清除NPM缓存
```
npm cache clean --force
```
或使用--legacy-peer-deps选项运行命令
```
npm install --legacy-peer-deps
```
或使用--force选项运行命令
```
npm install --force

npm install element-ui@2.15.3

错误

执行 npm install npm@latest -g 升级到最新版本（若升级到最新版本还是报错，则还需要再全局更新一下npm，更新后检查npm版本号不会变，内部应该有更新）；
.删除本地node_modules 依赖包；
执行 npm cache clean --force 清理缓存；
npm i 安装依赖；
以上过程，尝试一次不行，可以多尝试几次就OK了

npm i element-ui @xdh/my --legacy-peer-deps

`npm install npm -g` 更新一下

我这里是使用清除npm的缓存解决的（npm cache clean --force）

错误

解决方案：

降级npm到6版本，在终端运行以下命令

npm install --legacy-peer-deps

npm install vue@2.5.17 --save

npx -p npm@6 npm i --legacy-peer-deps

这个错误通常是由于 npm 无法解决依赖关系而引起的。你可以尝试以下几个步骤
1.清除npm 缓存: npm cache clean --force
2.更新 npm: npm install -g npm@latest
3.删除 node modules 文件夹:rm -rf node modules
4.删除 package-lock.json 文件: rm -rf package-lock.json
5.重新安装依赖: npm install
