Platform

Microsoft Windows NT 10.0.22621.0 x64

Subsystem

No response

What steps will reproduce the bug?

1. 在官网连接：https://nodejs.org/en/blog/release/v24.14.1下载[Window版本的msi格式安装包](https://nodejs.org/dist/v24.14.1/node-v24.14.1-x64.msi)
2. 双击安装node-v24.14.1.msi后，重启终端（默认为powershell7）
3. 输入命令npx -c "hello world", 出现弹窗错误

How often does it reproduce? Is there a required condition?

目前在我的机器上，v22.11之后的版本好像都有这个问题，经测试vmware上的ubuntu22系统安装的node并没有这个问题。

可能的条件：在我的机器环境中我之前已经安装了nvm来管理node，但是在安装隔离node时，我使用了nvm off来关闭了nvm管理的node版本

What is the expected behavior? Why is that the expected behavior?

1. npx -c is normal
2. i hate the error alert window

What do you see instead?

the following argument was not expected: -c
Run with --help for more information

npx -c "hello world"

is an invalid command.

npx -c "echo hello world"

would be a valid command.

This does not look like a bug in Node.js.

Windows build 10.0.22621.0 is for Windows 11 22H2 which is listed as past end-of-support according to https://learn.microsoft.com/en-us/lifecycle/products/windows-11-home-and-pro

Mixing different ways of installing Node.js can cause strange errors. You can try completely uninstalling nvm and Node.js, checking for any left-over paths in environments variables, then re-install.

感谢你的回答，我是需要去了解一些npx与node相关知识了，总结确实不算bug，最开始是我在部署openclaw以及一些使用node搭建的mcp或skills时，可能相关依赖调用了npx来执行一些命令，然后就开始弹出错误的弹窗，这么说的话就是依赖本身调用参数的问题了
