我在本地计算机上成功安装了nodemon，但是当我运行代码时，它给出了以下错误消息。
这是错误详细信息
The term 'nodemon' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was
included, verify that the path is correct and try again.
At line:1 char:1
+ nodemon
+ ~~~~~~~
+ CategoryInfo : ObjectNotFound: (nodemon:String) [], CommandNotFoundException
+ FullyQualifiedErrorId : CommandNotFoundException
我遇到了同样的问题，简单修复首先检查环境变量路径中是否存在路径
检查
控制面板>系统>高级系统设置>环境变量>双击PATH
现在检查您是否有此路径C:\Users\yourUsername\AppData\Roaming 下午
如果没有，您将看到一些现有路径，只需追加到其中并用分号分隔即可。就是这样！为我工作。
添加路径C:\Users\yourUsername\AppData\Roaming pm 在环境变量路径
在 Windows 上试试这个
打开 PowerShell 并输入以下命令。
A）
Set-ExecutionPolicy RemoteSignedB）
Set-ExecutionPolicy UnrestrictedC)
Get-ExecutionPolicyD）
Exit这对我有用：这应该将策略限制为当前用户。
Set-ExecutionPolicy RemoteSigned -Scope CurrentUser我找到了解决方法，只需进入 package.json （在您输入 npm init 后创建的文件）并在“脚本”下输入
start: "nodemon <filename>" 我全局安装了nodemon并且它开始工作了：
npm install -g nodemon
我也遇到这个问题了
我在本地目录中安装了nodemon并尝试运行
nodemon index.js然后我得到了上面的错误
我运行了
npx nodemon index.js我也遇到了同样的问题，但没有任何效果。花了几个小时终于找到了解决方案。
如果您使用的是 Windows，请按照以下步骤操作=>
如果您使用的是 powershell，那么
打开 PowerShell 并输入以下行。
设置执行策略远程签名
设置执行策略不受限制
获取执行策略
退出
如果您使用命令提示符，那么
在开始菜单中搜索“cmd”，然后右键以管理员身份运行。 现在您将运行管理员命令提示符。
输入这些说明=>
1)PowerShell 设置执行策略 RemoteSigned
2）PowerShell 设置-执行策略不受限制
3)PowerShell 获取执行策略
4)PowerShell 退出
现在尝试nodemon [你的节点应用程序] 现在您的nodemon 应该可以正常工作了。 还要确保你已经全局安装了nodemon npm install -g nodemon。 谢谢！
以下是针对 Windows 用户的一些步骤：
打开PowerShell并输入：
Set-ExecutionPolicy RemoteSigned (yes)
Set-ExecutionPolicy Unrestricted (yes)
Get-ExecutionPolicy
Exit
可能它仍然无法在您的 IDE 中运行。如果发生这种情况，只需关闭并重新打开 IDE，然后尝试再次运行它。
另一种选择是您必须转到终端 (windows + r) 并运行：
npm install -g nodemon
这三个步骤应该可以解决任何情况下的问题。
在 cmd 中输入 npx nodemon server.js 然后它将启动...
例如，
[nodemon] 2.0.15
[nodemon] 随时重启，输入
rsnode server.js这在 Windows 10 上也给我带来了问题。 我的解决方案有效：
npm 我的nodemon --save-dev
“main”：“app.js”，
"scripts":{"watch": "nodemon ./app.js"}
npm 运行手表
