启动前端

1.下载前端项目：https://github.com/huangyf2013320506/magic_conch_frontend.git
2.切换到项目目录下：cd /home/grad_user/magic_conch_frontend-master
3.执行npm install
报错：zsh: command not found: npm
解决：使用 Node.js 官方二进制文件安装（无需管理员权限）
（1）下载 Node.js 二进制文件：

wget https://nodejs.org/dist/v18.16.0/node-v18.16.0-linux-x64.tar.xz

（2）解压文件：

tar -xf node-v18.16.0-linux-x64.tar.xz

（3）移动到合适的位置：

mv node-v18.16.0-linux-x64 $HOME/nodejs

（4）将 Node.js 和 npm 添加到环境变量：

export PATH=$PATH:$HOME/nodejs/bin

export PATH=$PATH:/home/grad_user/nodejs/bin

（5）验证安装：

node -v
npm -v

再次执行npm install
成功：
