Windows on Arm

[u9520107]

Any plans or status on windows on arm support?

fnm itself can stay in x86 as the performance is good enough. But on windows on arm machine, trying to install node v20.x that has official windows on arm support now, fnm would still just install the x86 version.

Are there prebuilt binaries for windows arm? I would 100% support a fix for this

I think so. I am assuming you're referring to links like these? I think these are available for v20.x onward.

https://nodejs.org/dist/v20.9.0/win-arm64/ https://nodejs.org/dist/v20.9.0/node-v20.9.0-arm64.msi https://nodejs.org/dist/v20.9.0/node-v20.9.0-win-arm64.7z

That’s perfect. Do you want to contribute? I might have some minutes so send you links. I’m in reserves right now and we have a war so I’m not fully available. But I think that’s a perfect small PR :)

I can fork and try. But my rust is beyond rusty... might take a while.

@Schniz I just realized that with the --arch parameter, it is already possible to install the arm version on windows on arm.

In this case, perhaps it's not a good idea to change the premise that when the system can run multiple architecture, fnm will choose the same arch as the fnm build itself.

I'd say this issue can be closed. An arm64 build of fnm itself is welcomed, but not really necessary in my opinion.

The Node.js architecture can be defaulted to Arm64 using an environment variable.

https://github.com/Schniz/fnm/blob/master/docs/commands.md

--arch <ARCH>
Override the architecture of the installed Node binary. Defaults to arch of fnm binary

[env: FNM_ARCH]

Thanks for the issue and comments. Switching from Node.js installer to fnm.

Here's a PR to build Windows arm64 binaries for fnm: https://github.com/Schniz/fnm/pull/1250
