With tests disabled (DEB_BUILD_OPTIONS=nocheck ) I was able to build and install webpack 4.0

While trying to build node-d3-force I got

webpack --config debian/webpack.config.js \     --output-library=d3 \                           index.js build/d3-force.js                                                                      Insufficient number of arguments or no entry found.                                             Alternatively, run 'webpack(-cli) --help' for usage info.                                                                                       Hash: 057b6f22e319e519204a                      Version: webpack 4.0.0                          Time: 88ms                                      Built at: 28/7/2019 5:55:18 pm                                                                  WARNING in configuration                        The 'mode' option has not been set. Set 'mode' option to 'development' or 'production' to enable defaults for this environment.                                                                 ERROR in Entry module not found: Error: Can't resolve './src' in '/home/praveen/forge/node-d3-force'

I think all reverse dependencies will need updating as "mode" seems mandatory.

Feel free to try it out and help with updating reverse dependencies.
