The problem
When running npm install node-sass on OpenBSD, you may see the error below or similar one.
> node-sass@4.12.0 postinstall $APP_DIR/node_modules/node-sass
> node scripts/build.js

The solution
It is because clang++ is required but instead what is actually used is g++.
Therefore, the successful way is:
$ # case npm:
$ env CXX=/usr/bin/clang++ npm install node-sass
$ # case yarn:
$ env CXX=/usr/bin/clang++ yarn install node-sass
It will be successful like this:

Tips
Instead of in-line env, export and alias are also useful.
$ # case export:
$ export CXX=/usr/bin/clang++
$ npm install node-sass
$ # case alias:
$ alias npm='env CXX=/usr/bin/clang++ npm'
$ npm install node-sass
