nodePackages.vercel: it's not using the system Go for Go cloud functions on vercel dev

[lucasew]

Describe the bug

I am doing a project and running it locally using vercel dev.

This project uses a Golang cloud function on the API folder

Instead of using the system Go or reference it as a dependency it's using the provided go from @vercel/go so it triggers that problem when you run a binary that expects a FHS system but it's NixOS

Steps To Reproduce

Steps to reproduce the behavior:

1. Create a simple project with an HTML file or something like this
2. Add at least one cloud function (using the api folder using go
3. vercel dev

Expected behavior

vercel uses the system available Go, or the one declared as dependency

Please also convert the package to using buildNpmPackage when fixing this issue.

I think I found out the issue.

vercel dev looks for the go version in go.mod to know which go version to get. So the ideal here is to wrap vercel in a FHS environment so it works. Sometimes it's intentional using an older version.

[SuperSandro2000]

They are doing it wrong. The go keyword denotes the language version to use, not the compiler. They should just use the go version from PATH.
