Incorrect Python version used on Arch Linux

[saghm]

Build is failing on Arch Linux because the default Python version is 3.4 rather than 2.x:

Same issue on Gentoo, python at 3.5.0, I have a version < 3 installed but how do I specify it? Can't find docs with --python switch syntax.

[saghm]

--python is a switch for node-gyp, so I don't think there's any way to pass it directly when running atom update. However, I was able to update since then, although I'm honestly not sure what changed.

[iandoug]

npm install git-utils -g --python=python2

[saghm]

At least on Arch Linux, npm isn't a dependency for atom (at least, not in the binary package). Not that it's that much of a hassle to install it, but for people who don't otherwise want/need it installed, that might not be a preferred fix.

[iandoug]

No problem, I was just sharing a syntax use of --python which worked for me.
