+# 2018-07-14: BOTH STEPS ABOVE TAKE TIME, but Raspbian (apt offers npm
+# 1.4.21) & Debian 9 (apt offers no npm!) STILL NEED the above
+# nodesource.com approach to get a version of npm that works with Sugarizer:
+# https://github.com/iiab/iiab/issues/798#issuecomment-404324530
+#
+# MORE POSITIVELY: this nodesource.com approach (brings in npm 5.6.0 with
+# nodejs 8.11.3 for now, to any OS) would also work on Ubuntu 18.04, and
+# might even bring about a sane consistency across mainline OS's?
+#
+# BUT FOR NOW: Ubuntu 18.04's apt (approach below) brings in npm 3.5.2,
+# which appears suffic "SO FAR"?  18.04's nodejs 8.10.0 is more reassuring!
+
+# CRAZY IDEA: most versions of npm can upgrade themselves to the latest
+# (6.2.0 for now) using command "npm install -g npm", if that helps us in
+# future, e.g. TK's memory issue etc?  If so, be CAREFUL this puts npm
+# in /usr/local/bin on Ubuntu 18.04 -- unlike Ubuntu 16.04 and Raspbian
+# where it upgrades /usr/bin/npm in place:
