I'm trying to install n to downgrade node it gives me:

Unsupported platform for [email protected]: wanted {"os":"!win32"} (current: {"os":"win32","arch":"x64"})

If you know how to solve this please let me know.

CodePudding user response：

The official doc says:

n does not work in native shells on Microsoft Windows (like PowerShell), or Git for Windows BASH, or with the Cygwin DLL.

So yeah, your Windows machine is unsupported.
