Python 3 support by bumping node-gyp to 6.1.0

[ext]

I know similar pull requests have been declined before because it breaks compatibility.

However the current v4 uses node-gyp@3.8.0 which does not support python 3. Python 2 is now end of life since 1 jan 2020 and major distrubutions are starting to drop it (debian, fedora, ubuntu etc). Python 3 support landed in node-gyp@5.0.4.

This is a problem because node-sass will no longer work for new installations where the precompiled binary cannot be used (enterprise firewalls anyone?). So for this user group (myself included) node-sass is effectively unusable right now.

I've already seen that v5 solves this issue but I don't see a timeline and it doesn't seem to be actively worked on. So my suggestion is to either declare this project dead and force users to use a replacement such as dart-sass or merge this or a similar fix.

Since node-gyp@7.0.0 requires node 10 the minimal node version is bumped here as well. This makes sense since node 10 is the current oldest supported version.

EDIT: downgraded to 6.1.0 to support/require node 6 instead of 10.

Downgrading to "node-gyp": "^6.1.0", would provide compatibility w Python 2 & 3 and also support Node.js >= v6.

I guess that would make a transition easier, I've updated to PR to use node-gyp@6.1.0 instead.

I would like to add a +1 to this PR. We are having problems using node-sass on newer platforms that provide Python3

Any reason this hasn't been merged?

@keithslater Please do the following #2936 (comment)

Any reason this hasn't been merged?

It seems like the maintainers are moving towards deprecating node-sass and libsass in favor of dart-sass, see #2952.
