Pull Request

Problem

No arm64 binary found on m1 apple silicon
issue: #641

Solution

If no tarball found on Darwin os with arm64 arch, falls back to building from source tarball, as long as version is above 15.
I have successfully built the following versions:

node/12.22.1
node/13.14.0
node/14.5.0
node/14.16.1
node/15.0.0
node/15.12.0
node/15.14.0

but according to nodejs issue #37309, Support is very unlikely to be back ported to 14.x or before due to requiring a SemVer Major V8 update

ChangeLog

Fallback to building from source if no prebuilt binary found

Related: the nightly builds currently have an arm64 archive, although the index has not yet been updated.

You're right...
I just tried "n nightly" and got the following:

running n after that results in:

So maybe this pull request is not gonna be required...?

Building from source would be a big change and potential support burden with people asking questions about build or even runtime problems. For example, the Node.js building page is rather long.

I'm happy sticking with the pre-build binaries, which are just becoming available (hurrah!). I just saw a tweet this morning that Node 16 coming and featuring Apple silicon binaries:
