Vue 快速开发模板 - 项目说明书一、环境准备1.1 安装 nvmNode.js 版本管理工具nvm 用于管理多个 Node.js 版本方便切换。下载地址https://github.com/coreybutler/nvm-windows/releases 下载 nvm-setup.exe 安装即可1.2 使用 nvm 安装 Node.js# 查看可安装的版本 nvm list available 安装 Node.js 22.x LTS 版本 nvm install 22 切换到 22.x 版本 nvm use 22.x.x具体版本号 验证安装 node -v # 应显示 v22.x.x npm -v # 应显示 10.x.x1.3 常见问题nvm use 后 node -v 还是旧版本原因PATH 环境变量中有写死的旧版本路径。解决方法 1. 右键此电脑 → 属性 → 高级系统设置 → 环境变量 2. 在 Path 中找到类似 D:\xxx\nvm\nvm\v14.21.3\ 的路径 3. 删除这一行 4. 确认 NVM_HOME 和 NVM_SYMLINK 环境变量存在 5. 关闭所有命令行窗口重新打开 6. 执行 nvm use 22.x.x再执行 node -v 验证1.4 常见问题npm 命令报安全策略错误错误信息无法加载文件 npm.ps1因为在此系统上禁止运行脚本。解决方法以管理员身份运行 PowerShell Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser 输入 Y 回车确认1.5 设置 npm 镜像国内加速npm config set registry https://registry.npmmirror.com1.6 安装 yarnnpm install -g yarn二、创建 Vue 项目2.1 安装 Vue 脚手架yarn global add vue/cli vue --version # 应显示 vue/cli 5.x.x2.2 创建项目# 切换到你想放项目的目录 cd D:\你的目录 创建项目 vue create quick-dev-template2.3 创建时的选项配置第1步选择 Manually select features手动选择功能 第2步勾选以下功能空格键选中回车确认 ✅ Babel ✅ Router ✅ Vuex ✅ CSS Pre-processors ✅ Linter / Formatter 第3步Vue 版本选择 3.x 第4步Use history mode for router?
