问题描述

已通过npm i nodemon成功安装nodemon，但在VS Code的PowerShell终端执行nodemon命令时提示未识别，终端报错信息如下：

PS D:\my-express-server> npm i nodemon

added 32 packages, and audited 90 packages in 6s

PS D:\my-express-server> nodemon -v

解决方案

用npx直接调用本地包
本地安装的nodemon未加入系统PATH，可通过npx直接调用项目内的nodemon：
```
npx nodemon .\server.js
```
在package.json中配置启动脚本
打开项目的package.json，在scripts字段添加启动命令：
```
{
  "scripts": {
    "dev": "nodemon server.js"
  }
}
```
之后在终端执行：
```
npm run dev
```
全局安装nodemon
若需要在任意终端直接使用nodemon命令，执行全局安装：
```
npm install -g nodemon
```
安装完成后重启VS Code终端，再执行nodemon -v验证是否生效。
调整PowerShell执行策略（全局安装后仍报错时）
以管理员身份打开VS Code终端，执行命令修改执行策略：
```
Set-ExecutionPolicy RemoteSigned -Scope CurrentUser
```
按提示输入Y确认，重启终端后重试nodemon命令。
