1，安裝vue cli 腳手架，是全局安裝
npm install -g @vue/cli
可以在輸出信息中看到安裝位置，例如：
C:\Users\xiaochangjian\AppData\Roaming\npm\node_modules\@vue
2，查看腳手架是否安裝成功
vue --version
3，cmd 定位到要創建項目的目錄位置
4，vue create 項目名字 如：vue create ruoyi-front-ui

----------------------------------------------------------------------------------------------------------------
選中所有：
Use class-style component syntax? (Y/n) 是否使用class風格的組件語法？
Pick additional lint features？ Lint on save // 保存就檢測
? Save this as a preset for future projects? (y/N) N //是否記錄下，以便下次繼續使用這套配置
Vue CLI v4.4.6
? Please pick a preset: Manually select features
? Check the features needed for your project: Babel, TS, PWA, Router, Vuex, CSS Pre-processors, Linter, Unit, E2E
? Use class-style component syntax? Yes // 是否使用class風格的組件語法？
? Use Babel alongside TypeScript (required for modern mode, auto-detected polyfills, transpiling JSX)? Yes 這個選項的意思是要不要使用 babel 工具自動爲轉換後的 TypeScript 代碼注入 polyfiills 。如果實在搞不清楚具體是什麼意思，可以先不用管，直接選擇 Y ，進入下一步
? Use history mode for router? (Requires proper server setup for index fallback in production) Yes 是不是用history模式來創建路由
? Pick a CSS pre-processor (PostCSS, Autoprefixer and CSS Modules are supported by default): Less 詢問項目的CSS預處理器 選擇LESS
? Pick a linter / formatter config: Standard (詢問項目的格式校驗方式，提供一個插件化的javascript代碼檢測工具 ESLint + Prettier //使用較多)
? Pick additional lint features: Lint on save 詢問項目的什麼時候校驗格式(1是保存時，2是提交時)
? Pick a unit testing solution: Mocha （Mocha 靈活，Jest 安裝配置簡單容易上手）
? Pick an E2E testing solution: Cypress （Cypress E2E功能測試框架 會安裝很長一段時間）
? Where do you prefer placing config for Babel, ESLint, etc.? In dedicated config files 詢問項目的配置文件存放在哪兒（1是獨立文件，2是在package.json）這裏選擇獨立的文件，選擇2在後續配置postcs適配時存在問題。
? Save this as a preset for future projects? (y/N) 是否作爲一個模板配置
